I have BE 9.0 with patches running on 15 servers. If I try and use the AOFO 90% of the servers backup no problem but always when the backup gets to 1 server I always receive 00000079 HEX, The Semaphore timeout period has expired. If I disable AOFO the server backs up with skipped files. I am runnging BE 9.0 on NT4 SP6a. Compaq various servers and 3 LTO 100 gig Drives. I have swapped the drives around just in case but still same problem. Any Ideas ???
