- CA ARCserve Backup cannot recover data at file level granularity when you back up VHD volumes mounted inside the VM.
Be aware of the following considerations:
- This limitation applies only when using the raw (full VM) backup mode with the Allow file level restore option specified.
- This limitation does not apply to backups executed using the Client Agent for Windows. CA ARCserve Backup cannot recover data at file level granularity using only the Client Agent for Windows.
- CA ARCserve Backup does not support using VSS to back up nested VHD volumes that contain more than one level of data.
Consider the following example:
- Disk 0 contains drive C:\.
- Drive C:\ contains mounted volume drive V:\.
- Drive V:\ contains mounted volume drive W:\.
CA ARCserve Backup cannot detect the .vhd file that resides in drive V:\.
To protect data files that reside in drive W:\, you must submit the backup using Client Agent for Windows with CA ARCserve Backup Agent for Open Files.
- CA ARCserve Backup creates separate backup sessions for mounted volumes that contain VHDs.
Consider the following example:
- A server contains physical disk (C:\) that contains VHDs D:\ and E:\. VHD files (D.vhd and E.vhd) that reside in C:\ are mounted as drive D:\, and drive E:\. Drive D:\ is mounted to C:\MountD, and drive E:\ is mounted to C:\MountE.
- If you back up C:\MountD and specify the Traverse Directory Junctions and Volume Mount Points option, CA ARCserve Backup creates separate backup sessions for drive D:\ and C:\MountD.
- If you back up C:\MountE and specify the Traverse Directory Junctions and Volume Mount Points option and the Backup Mount Points as Part of the volume that they are mounted on option, CA ARCserve Backup creates separate backup sessions for drive E:\ and C:\MountE.
Note: The following options are located on the Backup Manager, Global Options, Advanced dialog:
- Traverse Directory Junctions and Volume Mount Points
- Backup Mount Points as Part of the volume that they are mounted on
