The files and folders restore fails for original location

When attempting to restore files and folders to their original location in a guest VM, the operation may fail due to an unsupported root file system on the client.

Cause:

The root file system on the client is Btrfs, which is not supported for mount point mapping during restore operations. As a result, NetBackup maps files using the device path (for example, /dev/sda3/...) instead of the actual mount point. Since the restore process cannot create files directly on device paths, the original location restore fails.

In the Activity Monitor, you may see:

Error bpVMutil: Failed to restore the selected files and folders.: SYM_VMC_CONNECT_ERROR
Info bpVMutil: Finished restore operation in guest VM.
Info bpVMutil: Successfully deleted VM <temporary_VM_ID>
VMware policy restore error(2820)
In the nbtar_rt log (if AGENTLESS_KEEP_STAGING_LOCATION = 1 is set in bp.conf), you may find:
ERR - Failed to create parent directory /dev/sda3/sanyukta. [Not a directory]

Resolution:

Perform an alternate location restore instead of restoring to the original location. This bypasses the unsupported device path issue and allows the restore to complete successfully.
