File Compression Server 2008

Have a 2008 File server that is using and EMC NS-120 for iscsi shares.  Several shares are spanned drives with file compression turned on(I didn't do)  Backups are taking an extraordinary amount of time with slow throughput (600mb/s) I would like to turn off file compression but don't want to screw anything up.. Am I ok to do this?

What is in those folders ?
You could create a new Folder and move data as this too will help with Uncompression as if its on that folder :)

Uncompressing the data will simply take lots of time and increase disk usage. I mean it will reduce available space on the drive. Nothing will be screwed up. As far as I understood you are using NTFS compression on this drive - right?

yes its just NTFS compression, but I'm thinking it might be a reason the backups are taking such a long time...am I wrong with that train of thought?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

What backup software are you using? NTFS compression should not affect the speed of the backup. If you simple xcopy the same data without using backup - does it take the same long?

backupexec 2010 R3.  I wonder if the issue might be the software raid/spanned drives. But it takes a really long time...see attached..almost 30 hours

Was it always so or did it start recently taking so long?
What about simple Windows xcopy of the same data to the storage that you take backups to? This will let you check if the problem is on hardware or in backupexec settings.

its backing up to a tape device..and yes its always taken this long

If you can afford this then try to backup to some other device such as internal HDD and see the difference. IMHO the cause could be in driver that is responsible for writing data to tape drive.

the other jobs to same tape library get 1800-2100mb/s throughput

Jobs from the same shares or from different sources?

different sources

Then I would try to create a new job for part of the shares then uncompress them and see if you have the difference. Although I would also suspect the HDD amd scsi interface you are using.
