CA ARCserve D2D for Linux provides the following backup features:
Block Level Incremental Backups
Ad-hoc Backups
Backup Status Monitoring
CA ARCserve D2D for Linux provides the capability to monitor:
Job Status Monitoring
CA ARCserve D2D for Linux provides the capability to monitor:
RESTORE
CA ARCserve D2D for Linux provides the following restore features:
Types of Restores
CA ARCserve D2D for Linux provides the following types of restores:
Restores any backed up files/folders.
LIVE CD
Live CD is used to boot a bare-metal machine for a BMR job using the IP address. Live CD lets you access the CA ARCserve D2D for Linux user interface (UI) without installing the product. You can use this option if you want to explore and use the product without installing the software. You can perform all the tasks of CA ARCserve D2D for Linux using the Live CD. You can also install CA ARCserve D2D for Linux from the Live CD. The advantage of installing from the Live CD is that you do not have to install the restore-utility package separately.
WEB-BASED CENTRAL MANAGEMENT UI
The CA ARCserve D2D for Linux UI lets you centrally manage all the nodes, jobs, backup storage locations, and D2D Servers. You can access the UI from any computer using the URL of CA ARCserve D2D for Linux.
D2D Server Management
CA ARCserve D2D for Linux provide the capability to manage several D2D Servers from a central interface.
Node Management
CA ARCserve D2D for Linux provides the capability to manage the nodes from a central interface. You can add nodes, delete nodes, and modify nodes.
Job Management
CA ARCserve D2D for Linux provides the capability to manage all the jobs from one interface. You can run multiple backup jobs simultaneously. You can run, modify, cancel, and delete jobs from the interface. You can create job groups by adding multiple nodes to one job. The job group reduces the number of backup jobs to manage. You can easily manage multiple job groups instead of managing an individual job for each node.
Backup Storage Location Management
CA ARCserve D2D for Linux provides you the capability to manage your backup storage locations. You can add, modify, and delete backup storage locations. CA ARCserve D2D for Linux supports Common Internet File System (CIFS) and Network File System (NFS) backup storage locations. Apart from the CIFS and NFS, you can also store your backup data to the Local disk of your backup node.
Encryption/Decryption Support
CA ARCserve D2D for Linux provides the capability to encrypt and protect (with encryption passwords) your sensitive data and also decrypt the encrypted data after recovery.
The encryption uses Advanced Encryption Standards (AES) to protect your data.
INTEGRATION
CA ARCserve D2D for Linux provides you utilities to integrate with your existing IT environment.
Pre/Post Scripts
CA ARCserve D2D for Linux lets you run your script at specific stages of a running job. All pre/post scripts are centrally managed in the D2D Server.

Pre-Release (Alpha/Beta/Release Candidate) Considerations:
Note: Upgrading from any pre-release build of CA ARCserve D2D for Linux r16.5 to the Generally Available (GA) release build is not supported.
The following issues that are related to CA ARCserve D2D for Linux are known to exist in this release:
Consider the following third-party software limitations that can affect the performance of CA ARCserve D2D for Linux:
Symptom:
You have provided an NFS server version 4 as your backup destination and the host name of the NFS server is not registered to DNS. When you run the backup job, the backup job fails.
Solution:
Register the host name to DNS.
Symptom:
You have provided some version of Data Domain NAS using NFS as your backup destination. When you are performing a backup to that backup destination, the backup fails. The reason is that some versions of Data Domain NAS do not support the file locking mechanism of NFS. Such NFS shares cannot be used as a backup destination.
Solution:
To avoid this problem, use CIFS as your backup destination. If the backup job still fails when you provide CIFS as the backup destination, follow these steps:
echo "0" > /proc/fs/cifs/LinuxExtensionsEnabled
You can now submit the backup job for the node.
Symptom:
When you back up the RHEL 5.1 node, the setroubleshoot system service uses the system memory for the backup process. If you perform multiple backup jobs, the setroubleshoot service generates multiple alerts in the /var/log/messages file and it uses all the system memory. After many backups, the backup node memory is full and it does not have any free memory.
Solution:
To avoid this problem, stop the setroubleshoot system service on the backup node using the following command:
service setroubleshoot stop
