Compression - Speed up jobs?

Created: 11 Mar 2014 | 4 comments

Good afternoon,

I am looking at a couple of ways to speed up the back-ups we do with Symantec Back-up Exec 2012 and im wondering whether or not somebody can confirm if compressing back-up jobs will speed up the time taken to complete?

Also, is hardware compression the best route?

We use an Ultrium HH5 Tape machine.

I know I could test this out myself one night, but im cautious about making changes without doing a little research first.

If someone could advise I would greatly appreciate it.

Kind regards,

It very likely will, but a no one is capable of a guarantee.

Compression will definitely slow down your job due to the extra processing compressing the data. Using hardware compression offload the work to the tape drive so the slowdown is minimized but there will still be a slowdown
