Supported Functionalities

The agent supports the following functionalities:

• Multistreaming--Arcserve Backup lets you submit jobs using multistreaming at the VM level.
• Staging--Arcserve Backup lets you submit VM backup jobs to disk staging and tape staging devices.

  You can restore data at file level granularity directly from the staging device and from final destination media, such as tape media.

• Deduplication--Arcserve Backup lets you save disk space by eliminating blocks of redundant backup data.
• Multiplexing--Arcserve Backup lets you submit jobs using multiplexing.
• GFS and rotation backups--Arcserve Backup lets you submit GFS and rotation backup jobs.
• Makeup Jobs:
  • Raw (full VM) backups--Arcserve Backup restarts failed jobs at the VM level.
  • Incremental and differential backups--Arcserve Backup restarts failed jobs at the volume level.
• Compression--Arcserve Backup lets you compress VM backup data on the agent system or the Arcserve Backup server.
• Encryption--Arcserve Backup lets you encrypt VM backup data on the agent system or the Arcserve Backup server.
• CRC verification--Arcserve Backup lets you verify data integrity by supporting CRC verification on VM backup data.
• Spanned, Striped, Mirrored, and RAID-5 volumes--Arcserve Backup lets you protect VM data that resides in spanned, striped, mirrored, and RAID-5 volumes.
• Raw Device Mapping (RDM)--Arcserve Backup lets you back up data on volumes that contain Raw Device Mapping (RDM) configured in virtual compatibility mode. Arcserve Backup supports this capability on VDDK-based backups.

  When you restore data using the Recover Virtual Machine method, RDMs that are configured in virtual compatibility mode will be restored as normal virtual disks.

• Hyper-V Dynamic Memory--Windows Server 2008 R2 SP1 and Windows Server 2012 support the capability to adjust the amount of memory available to Hyper-V virtual machines dynamically as workloads on the virtual machines change. To support this capability, Arcserve Backup lets you recover virtual machines that were backed up with Hyper-V dynamic memory specified to the amount of memory that was originally allocated to the virtual machines.
