why does my backup run for 8 hours straight

I have a backup set for 9pm every night monday to Friday. On some days i come into the office at 8am and my backup is still running causing my server to lag. How can i make the backup process faster. Im only backing up 200GB each night?

Only 200GB? That can take quite a long time, depending on the backup media you are using. You could do incremental backups which would be a lot faster. For example full backup Friday night (when time is not an issue) and incrementals M-T.
To what media  are you backing up?

a 300GB maxtor USB 2.0 external drive

To USB that is slow. In theory it should take about an hour, in practice perhaps twice that, and then if you have verify enabled worst case scenario twice the duration of the backup. That would still only be 6 hours.

The USB drive is USB 2.0 but is the server also USB 2? If the server were USB 1 it could take up to 40 times longer but that seems excessive even for your results.

What are you using for backup software? Does it provide any sort of log that indicates backup time and verify time to help narrow down the bottleneck?

Has it ever been quicker?  What server make/model do you have?  Have you tried plugging the USB cable into a different port on the server?

RobWill's title of "genius" doesn't do him justice.  You are in great hands here.  He has taught me many things about SBS/SQL.  Yo RobWill.

Thanks samiam41, but hardly a Genius, just too much time on my hands. '
Also I'm not a hardware guy, which could be a hindrance here.

Still see modesty is your style.  Very cool.

I happen to like the hardware much more and figured I would throw some advice in for nothing more then to get a chance to work with a legend.  

8 hrs for 200GB could be about right depending on "what" he is backing up.  Open files, mailboxes, entire chunk of data on server, etc...

Really? At 400+Mbps?

My recommendation is to supply a little more info:

Has it ever been quicker?  
What server make/model do you have?  
Have you tried plugging the USB cable into a different port on the server?

You could also plug the backup device into another computer and try copying a large chunk of data.  Time it to see how long it takes.  Then use the same chunk of data on the server and try the test again.  That way you can compare apples to apples.  This would identify a problem with the server, with the USB port or the backup device.

I will try tonight to plug the Maxtor into another USB port.

Rob WilliamsCommented:
Sorry, I lost track of this question.
Have you confirmed if both the server and USB device are USB2.0
If so try copying a simple file to USB and time it. Make it a large file if possible. That way we can try to isolate if it is the transfer speed or the backup application causing the delays.

cmdolcet I have no objection to whomever you wish to award points, but how can you choose a post that is simply a series of questions as the correct answer. One of the reasons messages are not deleted and marked as the solution is to assist other readers in the future. This would be quite confusing for them.
If none of the above helped you can also request your points be refunded and the question deleted. If you wish to make changes click on the "request attention" link.

Its seems as if the issue was resolved by simply changing the USB port on the USB card. When I changed the USB port into another slot on the card, the backup time was as normal.

Rob WilliamsCommented:
Sounds like a bad port.
Perhaps then samiam41's ID:26284475 would be an appropriate solution.
Thanks cmdolcet for attending to this.

No problem, it is just that the solutions are as much for those that read later as for you.
Cheers!

Sorry for getting to the show "late".  I figured with RobWill watching over the question, you were in the best hands possible.  Thanks for the points and I hope that you received the solution you needed for your issue.  

RobWill, always a pleasure to work next to you and hope I get to more often going forward.  Take care.  

ModernMatt, great to see you again.
