Arcserve Backup uses the following different naming conventions for mount points:
Arcserve Backup creates a mount point directory (snapshot) on the backup proxy system when it executes a VDDK backup. Arcserve Backup names the snapshot using the convention that follows:
After the backup is complete, Arcserve Backup deletes the snapshot from the backup proxy system. If the backup does not complete successfully, the snapshot remains on the backup proxy system until you delete it from the ESX Server system. Subsequent backups are not affected by snapshots that remain on the backup proxy system.
