My clients use multiple USB drives that are rotated daily M-F. They are accustom to doing a full image on each disk and having it overwrite the existing image the next time each drive is used. This has never been a problem and follows the same paradigm as a tape backup that overwrites a tape each time a backup is run. In Backup & Recovery 10 the introduction of Vaults and Backup Plans has made this simple and extremely common way of backing up impossible. Many of my customers can only fit one backup on a disk and need it to overwrite each time it is used. In the past an archive (i.e. servername.tib) could be created and overwritten each week. Now you tell Acronis that you want to create a full backup with an archive named servername.tib and it will create something like "servername_2009_08_03_20_00_05_913D.TIB". Appending this timestamp information to the archive name makes each backup unique. The next week when the disk is used again it does not overwrite the previous weeks file. Instead it creates a new one with a unique name. In the backup plan setup you can identify retention settings to delete archives that are a certain number of days old or limit the size of the total archive. However, when you do this it creates a MANUAL Cleanup Task that does not run before the backup job. You would need to manually run the cleanup task every day to delete anything off of the backup disk. We manage and monitor backups for our clients and they just rotate disks. They are not going to go in every day and run manual cleanup tasks. This is horrendously inefficient for us if we have to remotely connect and run manual cleanup tasks daily on all of our client's servers. If you delete the previous archive on the disk manually then it starts creating archives with names like "RecreatedArchive_89C380CC-4731-4761-A453-CDB3E27BFF77_2009_08_06_19_04_52_447D.TIB". These will never get overwritten either. There is absolutely no way to simply rotate a disk each day and have a full backup image written to the disk overwriting the existing image if present. This is the most basic and logical way to do a nightly backup and Acronis Backup & Recovery 10 has removed this functionality from it's product. This has rendered it useless in all of my installed base. I have contacted support and the rep didn't have a clue about this monumental shift in functionality. He acknowledged that he could not figure out any way to do a basic full backup in a nightly disk rotation that didn't require manual intervention to remove the previous image. He said he will email me when he has a better answer.
