1.0 Welcome

Welcome to the CA ARCserve Central Host-Based VM Backup Release Notes file. This document contains the following information relating to use of CA ARCserve Central Host-Based VM Backup:

• System requirements, operating system support, application recovery support, and other information you may need to know prior to installation of this product.
• A list of known issues and limitations that you should be aware of before you use this product.

Note: For information about system requirements, supported operating systems, known issues, and so on for CA ARCserve D2D, see the CA ARCserve D2D Release Notes.

2.0 New Features

This Release Summary describes new features, functional and usability enhancements, and dropped support included with CA ARCserve Central Host-Based VM Backup r16.5.

r16.5 Update 1:

• CA ARCserve Central Host-Based VM Backup is now enhanced to protect non-Windows virtual machines that run on VMware ESX Servers. You can perform full and incremental backups, and can recover VM operations. However, you cannot perform file or application level restore from non-Windows virtual machine backup sessions.

r16.5:

• The application supports the following Microsoft Windows 8 and Microsoft Windows Server 2012 feature:
  • Storage Spaces: Storage spaces is a virtualization layout that can group a quantity of physical disks and create virtual disks on top of the physical disks. With this release, CA ARCserve Central Host-Based VM Backup does not support application level recovery on Windows Server 2012 and Windows 8 systems where storage spaces are enabled, however the entire virtual machine can be recovered.

    Note: Creating storage spaces and virtual disks in BMR is not supported.

• Catalog-less Backup:

  File system catalog generation is a time consuming task. With this feature you can choose not to generate a catalog file with every backup, and still be able to do a file level restore. This reduces the backup time window.

• Microsoft Exchange 2013 Backup/Restore (VSS) is supported.
• UEFI Support:

  You can perform BMR from a backup taken on a UEFI machine to a BIOS machine and from a BIOS machine to a UEFI machine.

• vSphere 5.1 is supported.

3.9 Supported Disks

Different types of disks are supported for CA ARCserve Central Host-Based VM Backup backup source and destination disks. The following table matrix lists the types of disks that are supported for each function.

*Note: FAT/FAT32 cannot hold a single file larger than 4 GB. CA ARCserve Central Host-Based VM Backup creates CA ARCserve D2D files and if the file is larger than 4 GB after compression, the backup fails.

4.0 Known Issues

The following list provides information about issues known to exist in this release of CA ARCserve Central Host-Based VM Backup.

• The following issues relate to changed block tracking (CBT):
  • Backups of virtual machines can fail due to CBT requires a reset after the Preflight Check (PFC) utility reported that CBT is enabled on the virtual machine. This behavior can occur when ESX Server systems restart after the PFC utility completed the analysis of the virtual machine. The process of restarting ESX Server system requires a reset to CBT. There are no corrective actions required to remedy this behavior. After the job fails due to CBT not being enabled, Host-Based VM Backup enables CBT on the virtual machine. The next time the job runs, it should not fail due to CBT not being enabled, unless the ESX Server system was restarted again after the last backup job failed.

    Note: This behavior can also occur when ESX Server systems fail or reboot.

  • Backup jobs fail when the CBT feature is disabled and you have manually created snapshots on the virtual machine to back up. CA ARCserve Central Host-Based VM Backup automatically enables CBT on the virtual machine and you can then create the snapshot again.
• During a Recover VM job for Host-based VM backup, the vDS network configuration is skipped. After VM recovery, the vDS network configuration can be added manually.
• While recovering a VM to a specific ESX Server, if the VM version is not supported by the target ESX Server, the recover VM operation will fail. (For example, if you back up a VM with VM Version 8.0 from ESX server 5.0 and then try to recover to ESX server 4.0/4.1, the recover VM operation will fail because the VM Version 8.0 is not supported by ESX server 4.0/4.1).
• The application does not support protecting virtual machine data that resides on FAT/FAT32 file systems, ReFS volumes, and RAID 5 volumes. The backup jobs skip such volumes when performed on FAT and FAT32 files systems and RAID 5 volumes.
• Due to a known VMware issue, occasionally a snapshot named Consolidate Helper- 0 remains in the snapshot manager after the backup completes. This behavior occurs when you back up virtual machines that contain VMDK files that reside in different directories or LUNs and have identical file names. To delete the erroneous snapshots, turn off the virtual machines.
• The application does not support importing vCenter servers using VMware Linked mode. To protect all vCenter server instances in your Linked Mode group, add each vCenter server instance individually.
• Recovery points do not display immediately on the Browse Recovery Points dialog when you specify a shared folder as the destination for CA ARCserve D2D backups. To correct this problem, do the following:
  • After the Browse Recovery Points dialog opens, wait 30 seconds and click the dates on the calendar. This approach allows the dialog a sufficient amount of time to refresh and display the recovery points.
  • Reenter the credentials required to access the backup destination. To reenter the credentials, click the arrow next to the Select Backup Location field on the Browse Recovery Points dialog.
• The application supports protecting only Windows-based virtual machines running on VMware Hardware version 7 or later. When you import virtual machines from ESX Server and vCenter Server systems, the application skips UNIX-based virtual machines, Linux-based virtual machines, and guest operating systems that are not installed on virtual machines running on VMware Hardware version 7 or later.
• If you are running VMware High Availability (HA) or VMware Distributed Resource Scheduler (DRS), import nodes using a vCenter Server (not ESX) to avoid discovery and backup issues.
• Virtual machine names that contain JIS2004 characters appear in the VI Client as ??????. This behavior occurs only after you use CA ARCserve Central Host-Based VM Backup to recover the virtual machines. To correct this problem, rename the virtual machine using JIS2004 characters in the VI Client after the Recover VM operation is complete.

  To prevent this problem from occurring, name the virtual machine that you want to recover using standard (non-JIS2004) characters in the Recover VM screens while submitting the recovery job. Then, rename the virtual machine using JIS2004 characters in the VI Client after the Recover VM operation is complete.

• When  Catalog generation process failed for a successful HBBU backup check if the activity log show the below message
• When Host-Based VM Backup virtual machine backup jobs complete successfully and the catalog generation process fails, the following message appears in the Activity Log:

  Could not get volume information from virtual machine Guest OS.

  This problem can affect backup jobs that were successful previously. When this problem occurs, CA ARCserve Central Host-Based VM Backup generates the backup session but cannot generate the catalog files that are required to support the backup sessions. The failed catalog condition prevents you from performing file level restores because the catalog does not contain the recovery points that are required for file level restores.

  To correct this behavior, the following corrective actions may solve the problem:

  1. Examine the status of VMware Tools on the PFC dialog. When the status indicates Out of Date, install the latest version of VMware Tools and then resubmit the backup.
  2. When the guest operating system is Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2, provide the built-in or domain administrator credentials to log in to the virtual machine guest operating system.

     Note: Administrator credentials are required for virtual machine guest operating systems to generate catalog and perform granular restore.

• When you recover virtual machines to the original location, and specify the Overwrite existing VM option, Host-Based VM Backup changes the location of the virtual disk when it detects the presence of the original virtual machine. This behavior was designed to help ensure that you do not lose data during the Recover VM process.
• The application cannot send backup failed related alert messages when the CA ARCserve D2D virtual machine proxy system is down or the CA ARCserve D2D service on the proxy is not running.
• CA ARCserve D2D licensing error email messages occur under the following scenario:
  • CA ARCserve Central Host-Based VM Backup was uninstalled and then reinstalled.
  • The CA ARCserve D2D nodes that you were protecting before you uninstalled CA ARCserve Central Host-Based VM Backup were added using the Node screen.
  • The policy was redeployed.

  If you receive email messages that indicate that licensing errors occurred on the nodes, you can ignore the messages.

• When you sort the View Logs list by the name of the Module, the application sorts the list based on a predetermined sort order for the specific language.
• When you try to deploy CA ARCserve D2D to a remote node from the CA ARCserve D2D Home page, a message may appear that indicates that the user name, password, or both specified for the target node is not correct. This problem occurs only when you log in to CA ARCserve D2D from the CA ARCserve Central Host-Based VM Backup Node screen.

  Solution: Open a browser window and log in directly to the CA ARCserve D2D node using the following URL:

  http://<hostname>:<port>.

  From the new browser window, you can deploy CA ARCserve D2D to the target node without encountering the error message.

• CA ARCserve Central Host-Based VM Backup cannot back up USB volumes. If there are any USB volumes included in the backup source, CA ARCserve Central Host-Based VM Backup skips the USB volumes.
• The following behavior applies to backing up data that resides on NFS data stores:
  • When backing up data that resides on NFS data stores using changed block tracking, and you do not use data compression, the size of the first full backup will be at least the same size as the source disk. However, subsequent incremental backups will contain only the changed blocks of data. As a result, the overall size of the incremental backups will be smaller as compared with the first full backup.
  • An alternative approach to backing up virtual machines in NFS data stores is to install CA ARCserve D2D inside the guest operating system and back up the virtual machine in the same manner as you would back up a physical machine.
• If you have a vCenter server that is configured with a custom HTTPS port and then run a backup job using the default HTTP port, the backup job fails.

  To resolve this issue, use the HTTPS port for the backup job.

• To restore data to virtual machines that are implemented using Unified Extensible Firmware Interface (UEFI), ESXi Server 5.0 must be the hypervisor that is installed in the virtual environment. When ESXi Server 5.0 is not installed in the virtual environment, the recovery fails and error messages can appear.
• Backup jobs fail when all of the following conditions are met:
• Microsoft Windows Server 2008 and later contains a User Profile Service that unloads specific registry keys when users log out from the computer.
  • Microsoft SQL Server or Microsoft Exchange is installed on the server.
  • CA ARCserve D2D backup is user generated.
  • You log out from the server after the backup starts, but before it completes.

  To correct this behavior, use the following steps:

  1. Log in to the CA ARCserve Central Host-Based VM Backup server using the Administrator account or an account that is a member of the Administrators group.
  2. Type gpedit.msc in the Run dialog to start the Local Group Policy Editor.
  3. From the Local Group Policy Editor, expand Computer Configuration, Administrative Templates, System, and User Profiles.
  4. From the User Profile directory, double-click Do not forcefully unload the user registry at user logoff, to open the dialog.

     Click Enabled and then click OK.

     Note: The value DisableForceUnload is added to the registry.

  5. Type gpudate.exe in the Run dialog from the CA ARCserve Central Host-Based VM Backup server.

     Ensure that the security policy settings are updated.

• When you schedule an Incremental backup for a virtual machine; and then perform a Storage vMotion, the Incremental backup converts to a Verify backup.
• When you configure backups to always run using the SAN transport mode; backups fail when the SAN is not available. The activity log displays the following error message:

  Unable to open VMDK file %1!s!. VMware reported the following error: You do not have access rights to the file. For more information, see the debug log AFBackend.Log. If necessary, contact technical support.

  To correct this behavior, apply the SAN transport mode to the registry only if the SAN is available.

• When you submit a VMware based virtual machine backup and the backup fails, the following error message appears:

  Could not take snapshot of the virtual machine. ESX Server/vCenter Server reported the following error: Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.

  This is a known issue with VMware and is working to find a resolution. In the interim, we have listed some workarounds in our troubleshooting topic, Backups Fail with Snapshot Creation Errors in the CA ARCserve Central Host-Based VM Backup user guide.

• If you are using Google Chrome as your browser and you click a link from any of the Support and Community Access dialogs and no link opens, perform the following tasks to enable the link:
  1. Verify if there is a pop-up blocked icon displayed in the URL section.
  2. Click the icon and select the "Always allow pop-ups from <YOURSERVERNAME>" option.
  3. Restart Google Chrome. The links from CA ARCserve D2D should open successfully.
  4. If the data is still not shown in the correct format, check if RSS extension for the Google Chrome browser is installed or not.
  5. If not installed, download and install the RSS extension for the Google Chrome browser and reopen the links.
• When you submit or schedule an Incremental backup job for a virtual machine on an ESX 5.0 server; a Verify backup job runs instead. Follow these steps to correct this behavior:
  1. Right-click the virtual machine that is converting Incremental backups to Verify backups.
  2. Select Snapshot and then select the Consolidate option.
  3. When the consolidating process completes, resubmit or reschedule the Incremental backup job and confirm that the backups are not being converted to Verify backups.
• The process of generating catalogs may stop responding when the volume extent is spread across a disk.

  Symptom:

  The volumes extent cannot have more than one logical extent across a disk. This behavior occurs on striped volumes and does not occur on simple, mirrored, and spanned volumes.

  Solution:

  To prevent this behavior from occurring, the volumes extent should be contiguous on a disk.

• Intermittent failures in backup, restore, merge, and other operations are observed if a network share on a "HP StorageWorks D2D4106" device is used as the backup destination for CA ARCserve Central Host-Based VM Backup. It is not recommended to use this device for the backup destination.
• For uncompressed and unencrypted backups, it may not be possible to resume the merge after pausing it. CA Technologies is in the process of resolving this issue.

r16.5

• When you configure storage space on a VMware or Hyper-V virtual machine or when the virtual machine contains applications with data on SMB shares; backing up the virtual machine fails with a snapshot creation error.
• To mount deduplication NTFS volumes, verify that the volume is mounted on a Windows Server 2012 system and the deduplication feature is installed.
• Host-based VM backup jobs have been known to stop responding. When you encounter this condition, configure the application to use the NBD transport mode for backups. For more information, see Define a Transport Mode for Backups in the CA ARCserve Central Host-Based VM Backup USer Guide.
• CA ARCserve Central Host-Based VM Backup does not support protecting virtual machines that are configured as SE (Space Efficient) disks. Volumes that are configured in this manner will be skipped during backup operations.
• When a virtual machine contains SCSI and IDE disks or SCSI disks on different controllers, CA ARCserve Central Host-Based VM Backup fails.
• If you have the combination of Microsoft SQL Server 2012 SP1 (64-bit) and Microsoft SQL Management Studio, uninstall Microsoft SQL Management Studio before installing CA ARCserve Central Host-Based VM Backup. For more information, see Article 770630 on the Microsoft website.
• When storage space volumes reside on virtual disks, the application cannot back up the data that resides on the virtual disks, and the volumes do not appear (listed) on the Browse Recovery Points screen and the Copy Recovery Point screen. You can expect this behavior because volumes that reside on virtual disks that the storage pool created are not listed and protected by CA ARCserve Central Host-Based VM Backup. In addition, the file level restore and the mounting drivers for such volumes are not supported.
• CA ARCserve Central Host-Based VM Backup Catalog job fails intermittently on virtual machines running Windows Server 2003 x64 SP2 Enterprise Edition with the error message "Failed to generate catalog".

  Note: We are working with VMware to resolve this issue. If you encounter this issue and need assistance, contact CA Support.

r16.5 Update 1

• When you perform Incremental backup jobs for VMware virtual machines, the size of the Incremental backup jobs is larger than expected. This is a known VMware issue where it involves Changed Block Tracking (CBT). To correct this behavior, set the following registry:

  [HKEY_LOCAL_MACHINE\SOFTWARE\CA\CA ARCserve D2D\AFBackupDll\<VM instance UUID>]

  "ResetCBT"=dword:00000001

  Example:

  [HKEY_LOCAL_MACHINE\SOFTWARE\CA\CA ARCserve D2D\AFBackupDll\502d3c43-e3c9-9919-78f9-89082ca5e1cc]

  "ResetCBT"=dword:00000001

  Note: After the registry value is set, the next Incremental backup job converts to a Verify backup job and then the subsequent Incremental backup jobs continue to run with the appropriate size.

• When you power on a recovered virtual machine (VM) that contains a virtual flash read cache, the virtual machine fails and displays the following error message, "The available virtual flash resource ('0' bytes) is not sufficient for the requested operation". This error occurs when the target (ESX) host does not have the virtual flash resource or when the target host virtual flash resource is less than the size of the VM virtual flash read cache.

  To resolve this issue, set the virtual flash read cache to 0 in the recovered VM settings and then power on the VM.

• The VMware ESXi server stops working when you use E1000E/E1000 vNIC Adapters on virtual machines that run on VMware ESXi. As an alternative solution, refer to the following VMware Knowledge Base article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2059053

r16.5 Update 2

• With version VDDK 5.5 or later, the Hot Add Transport mode will not work with ESXi level but will work with VC level. When Hot Add Transport mode is selected, the mode is changed back to NBD mode. This behavior occurs in CA ARCserve Central Host-Based VM Backup and CA ARCserve Central Virtual Standby.

5.0 Limitations

The following list provides limitations that are known to exist in this release of CA ARCserve Central Host-Based VM Backup.

• Due to a known VMware limitation, Host-Based Backup does not support application level restores from backup sessions of Windows 2008 or later or virtual machines running on ESX 4.0 or earlier. The application supports file system backups, file system restores, recover virtual machines, and bare metal recovery operations in this type of environment.
• Due to a known VMware limitation, CA ARCserve Central Host-Based VM Backup cannot protect ESXi virtual machines using a free license. To back up these virtual machines, apply a purchased license.
• Due to a known VMware VDDK licensing limitation, the following jobs should not be performed using custom ports (HTTP, HTTPS):
  • The message, "Cannot open VMDK file" is displayed when you try to back up a virtual machine using a VMware vCenter or ESX server custom HTTP port.
  • The message, "Failed to recover virtual disks" is displayed when you try to recover a virtual machine using a VMware vCenter or ESX Server customized HTTP port. This message is also displayed when you try to recover a virtual machine using a VMware ESX Server custom HTTPS port.
• Due to a known VMware limitation, errors in the Activity Log appear in English when the Location is set to a non-English locale.
• CA ARCserve Central Host-Based VM Backup now supports backing up data using Unified Extensible Firmware Interface (UEFI) with ESXi Server 5.0 installed on the virtual machine. If ESXi Server 5.0 is not installed on the virtual environment, the following error message appears:

  The application cannot recover this virtual machine because ESXi Server 5.0 is not installed on the virtual environment.

• Due to a known VMware limitation, there are times where VMware Storage vMotion cannot migrate a virtual machine which is being protected by CA ARCserve Central Host-Based VM Backup. To correct this behavior, see the following Knowledge Base article on the VMware website: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2008957
• Due to a known VMware limitation, when you protect a SQL Server running on a Windows Server 2012 virtual machine (VM) hosted on a VMware server with data stored on another Windows Server 2012 computer, it is required to install Client Agent or CA ARCserve D2D to the VM. CA ARCserve Central Host-Based VM Backup is not recommended as the backup method.
• Due to a known CA ARCserve Central Host-Based VM Backup limitation, the application does not support the following volumes:
  • Catalog generation for both stripped and RAID-5 Volumes.
  • Backup for RAID 5 Volume.

    Note: If the stripped volume contains more than one extent on one disk, then backup is not supported.

• CA ARCserve Central Host-Based VM Backup does not support application level recovery on Windows Server 2012 and Windows 8 systems where storage spaces are enabled, however the entire virtual machine can be recovered.

  Note: CA ARCserve Central Host-Based VM Backup can only protect ESXi virtual machines at the disk level. The application cannot protect the data that resides on the virtual disks that are created by Storage Space at the volume and file levels. The backup job will skip the volumes residing on the virtual disks that are created by Storage Space.

• Due to a known VMware limitation, sparse space efficient (SE) disks are not supported and will be skipped from the backup job. In addition, VMware specifies that the 'seSparse' virtual disk type is intended for internal use only. For more information, see the vSphere Web Services SDK 5.1 Release Notes on the VMware website.

  For information about VMware virtual machines that are configured with space-efficient (SE sparse) disks, see the VMware Knowledge Base article.

• When you manage ESX Server 5.0 and higher with vCenter Server and you try to recover a virtual machine directly to the ESX host, the recovery fails. To resolve this issue, disconnect the ESX server and then resubmit the recovery job to the ESX host.
• Due to a VMware limitation, CA ARCserve Central Host-Based VM Backup does not support Windows Server 2012 virtual machines that have ReFS volumes, NTFS Data Deduplication volumes, or both enabled. However, the application supports virtual machines running on Windows Server 2012 virtual machines that do not have ReFS volumes, NTFS Data Deduplication, or both disabled.

  As an alternative solution in supporting Windows Server 2012 virtual machines that has ReFS volumes, NTFS Data Deduplication volumes, or both enabled, install CA ARCserve D2D inside the virtual machines and perform the backup operations directly from the virtual machines.

  Note: VMware is working to resolve this limitation.

• A data corruption problem may occur when you have machines with Intel 82574L or E1000E vNIC network adapters on your CA ARCserve Central Host-Based VM Backup environment. This is due to a data corruption issue of this model of network adapters when using its TCP Segmentation Offload (TSO) feature.

  To avoid this problem, perform one of the following actions:

  • When creating a virtual machine in VMware, select different network adapters instead of E1000E.
  • For existing virtual machines that contain the E1000E vNIC network adapter; delete it, add a new adapter and connect it to the virtual network.

    Be aware of the following conditions:

    • Ensure that the environment where the CA ARCserve Central Host-Based VM Backup proxy server resides does not contain the Intel 82574L network adapter or the E1000E vNIC in its entirety.
    • If the backup destination is a share, then the computer hosting the share should not contain the Intel 82574L or the E1000E vNIC network adapters.
  • If you must use the E1000E vNIC or if you are using a physical computer with Intel 82574L NIC installed, it is recommended that you disable the TSO feature.

  For more information about this problem, see "Errata 17 - Tx Data Corruption When Using TCP Segmentation Offload" in the following Intel document:

  Intel 82574 Family Gigabit Ethernet Controller Specification Update

• CA ARCserve Central Host-Based VM Backup does not support granular restore for NTFS deduplication volume for the Windows Server 2012 R2 guest operating system.

  This limitation is only applicable to Windows Server 2012 R2 deduplication volumes because VMware has not certified Windows Server 2012 R2 as a proxy with VDDK 5.5. As an alternate solution, install CA ARCserve D2D on to the virtual machines and directly perform the backup operations.

• Due to VMware limitations, HTTP protocol and vSAN beta are not supported.
• In an Exchange Database Availability Group (DAG) environment, CA ARCserve Central Host-Based VM Backup can only truncate logs for the protected Exchange nodes. The following alternatives will result in log truncation on all DAG nodes:
  • Back up all nodes in a DAG.
  • Install the Agent inside the virtual machine on the active nodes by applying the procedure from the following KB article:http://www.arcserve-knowledgebase.com/index.php?View=entry&EntryID=3154.
  • Use CA ARCserve Backup Exchange Agent.
