When you back up data using disk staging, or copy media using the tapecopy command line utility, duplicates of backup sessions can exist in multiple locations. For example, you can define your staging copy and purge policies such that backup sessions remain on the file system device used for staging for a period of time after the copy to final destination media operation occurs. If the backup session was not purged from the file system device, data will reside on the file system device and the final destination media. If this situation presents itself, you can restore the session by using data that resides on the file system device.
When you copy media, duplicate backup sessions exist on multiple media. If one media remains on site and the other media was vaulted, you can direct CA ARCserve Backup to use the media that is on site to facilitate the restore operation.
To search for duplicate sessions, click the Duplicates button on the Version History dialog. The Duplicates Sessions dialog displays the original backup session and all of its copies. If duplicates for a session exist, CA ARCserve Backup lets you use the session that allows you to restore the session as quickly as possible.
