SnapManager stores backup data in backup sets. A backup set consists of all data that you need to be able to perform a restore process.
A backup set contains these components regardless of whether the data exists on the same LUNs and volumes or not.
SnapManager backup set names are displayed in the SnapManager Restore window and in the SnapManager Restore wizard. Backup set names include the name of the server and management group, as well as a timestamp.
