Your initial performance may be misleading because it could be buffered data.
I would make sure your tuning is in order; and then I would start investigating how the data is getting to the VTL...ethernet or fibre...what is the hardware in between...we ourselves in one instance discovered a 10 G NIC used by an IBM frame that had a performance bug...a 1 TB backup was taking like 5 hours! Now we have it down to 52 minutes. ...so crazy things can happen. -----Original Message----- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of NetCookingTalk Sent: Monday, June 20, 2011 8:14 AM To: VERITAS-BU@MAILMAN.ENG.AUBURN.EDU Subject: [Veritas-bu] Netbackup to VTL fast with first tape then slow thereafter post from Nathan: Thanks, when I checked the bptm logs I can see the throughput but no indicator as to why the second tape crawls. Nathan ============ I've seen some of my jobs start out good and slow to a crawl later. I had not cosidered that it might have changed tape in the process. I will see if that is the case on my end and will be very interested in the solution to this issue.
