Slow Tape Backups

Created: 01 Oct 2013 | 6 comments

I'm running Backup exec 2012 on a new windows 2008 r2 server with dual processors and 16 GB of ram.  It is using a 3 Gb SAS controller to connect to my Overland Neo 400s with two IBM half height LTO 6 SAS drives.  I have hardware compression and encryption turned on.  I am trying to backup two linux  servers, one has 7 TB of data and the other 20.  After 14 hours, one has backed up 1.4 TB of data and the other 400 GB.  It is utilizing both tape drives.

Processor usage stays at 1 - 2% and memory stays at 13%.  

How can I speed this up? At this rate it will take all month to do a full backup.

Hello, 

Make sure any antivirus scan has exclusions for the Backup Exec processes and that your tape drive is using Symantec drivers

There is no anti-virus, it's a brand new server and the only thing I've installed on it is Backup Exec.

It looks like the Overland Neo 400s with two IBM half height LTO 6 SAS drive is not supported. There is support up to LTO 5  See the Backup Exec HCL. http://www.symantec.com/docs/TECH175582

It does support those drives and it is working, it's just going slower than I had hoped.  The drives are expicitly supported under IBM.  I was also told by Symantec when I called in that it was supported.

Yes, you are correct!  I apologize I was looking at an older BE 2012 HCL.

 Do you have all of the most current Live Updates installed?

7TB and 20TB is a lot of data, especially if you have a lot of small files.  Small files will take a longer time to back up compare to a couple of big files, assuming that total amount of data in both cases are the same.

There are also a lot of other factors that come into play like the speed of the remote servers, speed of the NIC's of the remote and media servers and how congested is the network.
