Hello, thank you for reading.
I have a server whose volume of data backed up has not changed significantly, but whose Job Rate has dropped dramatically since April and I cannot figure out why. It is a backup-to-tape of less than 200GB on LTO-4, and it has gone from taking about 2 hours to taking 12+.
The backup is a Duplicate from a local backup-to-disk volume on the backup server. The Elapsed Time and Job Rate on the backup-to-disk job, which is linked to the tape job by template, has not changed significantly. I have gone through the job log and noticed that the generation of each subsequent (4 GB) bkf has taken longer than the previous one as the job progresses, with the first taking about 3 minutes, and the last taking 45 minutes.
I have a Server 2008 Standard x86 SP2 machine running Backup Exec 2010 R3.
I'm attaching a spreadsheet showing the progression of the backup-to-tape job, showing its tenfold decline in three months. The only troubleshooting steps I have taken so far have been to update the backup server, the backed-up server, and the tape drive, and to run a couple cleaning tapes through the drive.
Please help, and thank you!
