I am currently experiencing a similar problem, Retrospect is unable to backup Exchange server 2007 storage groups, when running the backup we receive the following error:
+ Recycle backup using OneOff at 26/02/2009 11:17 (Execution unit 1)
To Backup Set SecondStorageOneOFF...
26/02/2009 11:17:00: Recycle backup: The Backup Set was reset

Remaining: 2 files, 9.1 GB
Completed: 0 files, zero KB
Performance: 0.0 MB/minute
Duration: 00:00:32 (00:00:07 idle/loading/preparing)
We have two servers:
File server â€“ Windows Server Standard 2003 R2 32bit
Exchange server â€“ Windows Server Standard 2003 R2 64bit + Exchange Standard 2007
Retrospect is installed on the File server, version:
Current version: 7.6.123 single server
Hotfix version: 220.127.116.11
Client Version: 7.6.107 (on Exchange server)
The storage group backup was working until we installed the 18.104.22.168 driver and hot fixes update, it fails to backup the storage groups but can backup the individual user mailboxes and all public folders.
We have tried un-installing and forgetting the backup client then re-installing the backup client and re-connecting but the error still occurs.
Any help would be most appreciated.
