Mount points not available when restoring files from a Linux virtual machine
For Linux virtual machines, only the ext2, ext3, ext4, and XFS file systems are supported for individual file restore. If a partition is formatted with some other file system, the backup succeeds but NetBackup cannot map the file system addresses of the files. As a result, NetBackup cannot restore individual files from that partition. Only the files that were on ext2, ext3, ext4, or XFS partitions can be individually restored.
Note:
To restore individual files from their original mount points, the "/" (root) partition must be formatted as ext2, ext3, ext4, or XFS. If the "/" (root) partition is formatted with a different file system (such as ReiserFS), the mount points cannot be resolved. In that case, you can restore ext2, ext3, ext4, or XFS files from the /dev level (such as /dev/sda1). You cannot restore the files from their original mount point level.
