BE 2012 SP2 LTO 5 Speed Questions
I have had no formal training in Backup Exec products and most of my knowledge comes from experimentation and reading forums, so please forgive me for any glaring mistakes I may have made so far.
With that out of the way, I was wondering if anyone could give me some advice on avg. speeds I should be getting with LTO 5 tapes. I have a Dell Poweredge R710 hooked up by miniSAS to a OverlandStorage Neo100s tape drive. I use the Neo100s to back up 1 file/print server as well as an iSCSI disk from a NAS unit. The speeds I get for a full and incremental backup avg out to be 1000MB/Min. I have read other posts about fine tuning LTO performance, and I have tried changing my Block Size around and the high water count. Neither of these have seemed to do much in terms of changing the speeds I'm getting. I have tried doing backups for data located solely on media server, and data located on the iSCSI drive. The speeds I get then are 2100~MB/Min and 500~MB/Min respectively. I do incremental backups on weekedays and run a full backup on the weekend. The incrementals finish fast enough (40-50GB in an hour or two), but the full takes almost a whole day to do 1 TB of data. I also have made sure that the Symantec drivers are the drivers being used for my backup device. I have also reinstalled BE 2012 once before.
Does anyone have any helpful advice as to what I can do to possibly bolster the speeds?
Thank you for time
