I have a Dell server 2008R2 with repos and a SAS Dell tape library Ultrium 5.
Veeam 9.5 SP1
VMware 2D Jobs:
All disk jobs are forever forward incremental. Repo would be holding 4 to 9TB's
Files backups run's perfect at around 90-130MBs
A Tape backup using "Job" or "repository" and not selecting "archive incremental" run's perfect at around 90-130MBs
Looking at performance monitor I see 1 to 4 files open (usually the same VBK being access by different services).
If I enable "archive incremental" the job might run fast for a while but then drops below 25MBs making the job run for days..
Looking at performance monitor I see 10-30 files open (VBK and most of the VIB's). So looks like a Tape synthetic backup going to tape.
I have a local DAS SAS repo and an iSCSI 10GB Ethernet repo. both give the same very slow performance.
system has lasts firmware, tape drivers and have tried with and without native SCSI commands.
Is this normal behaviour?
I'm looking to backup the repo from the most resent full and all inc on day one of the week and then pick up the daily incremental every other day of the week. I also need the option to restore a single VM from the tape backup so using file mode won't work.
Without having to do a VBK backup every day of the week what options do I have?
