Can’t save Snapshot tree, error -1102
My Server 7.7.341 with two Mac 6.3.029 clients ceases functioning during Proactive backup after copying a few MBs. I am able to successfully complete manual backing up. The error details are as follows:
– 9/28/2011 12:44:36 PM: Copying Users on MAC1
Can't save Snapshot tree, error -1102 ( drive missing/unavailable)
9/28/2011 12:48:03 PM: Execution incomplete
Completed: 5 files, 25.3 MB
Performance: 151.7 MB/minute
Duration: 00:02:45 (00:02:36 idle/loading/preparing)
Every time the Proactive backup starts, it produces the same error. All other Mac systems work fine. I tried recreating the backup sets, moving a client to another server, uninstalling and uninstalling the clients etc. The problem reoccurs. How can I solve it?
