SBS backup taking too long after reboot - from 2 hours to 15 hours

This has happenend before. We are backing up only 22GB of data each night. Normally takes just under two hours to complete. I powered the server down over the holiday weekend and when it ran its first backup it took 15 hours. Today's backup is currently running and the system is quite slow.

The logs are attached. They do not reveal any insights, just document that the process time increased almost seven-fold. Some folks have suggested that I hack the NtBackup exe file to prevent a verify, but this is not the issue...we need to know why the backup magically takes much longer for no apparent reason.

Could it be that my USB2 device has slowed down to USB1 ? I've have not changed ports, but I have seen this happen on my XP boxes. I plan to test that when the backup ends.

Any ideas? Logs attached. Regular run plus slow run.

Thanks,
Keith

What are you backing up to? Could be worth reloading the drivers.

Hello rowek,

are you using ntbackup or the built in SBS backup software?

To answer both individuals:
I am using a HAMMER USB2 hard drive. There are no drivers to load. The O/S sees it as a USB device and installs it automatically.

We are using the built in SBS backup software. I am sorry if I mispoke on the ntbackup, old habits die hard.

Backup is still running. When it completes I will unplug the drive and reattach. It should tell me "This device could run faster if a USB2 port is used" or something like that. Keep in mind my DELL server only has USB2 ports, but I have seen on XP Pro where it only recognizes it as USB1 (very slow).

Backup will run for two more hours so I will go silent for a while. Thank you for writing back.

Hi,

The backup took almost 7 hours for the c drive backup

Backup started on 7/7/2008 at 8:02 PM.
Backup completed on 7/8/2008 at 3:06 AM.
Directories: 8106

Bytes: 22,348,789,357
Time: 7 hours, 4 minutes, and 10 seconds
and the verify operation another 6 horus

Verify Status
Operation: Verify After Backup
Active backup destination: File
Active backup destination: E:\SBS_Backup\Backup Files\Small Business Server Backup (05).bkf
Verify of "C:"
Backup set #1 on media #1

Where as the earlier backup on 07/03/2008 took only 1 hr 30 mts

Backup Type: Normal
Backup started on 7/3/2008 at 8:02 PM.
Backup completed on 7/3/2008 at 9:31 PM.
Directories: 8104
Files: 60839
Bytes: 22,332,979,607
Time: 1 hour, 29 minutes, and 23 seconds

the change in the amount of data that has changed is 15809750 bytes only. But the time difference of 6 hours is not justifiable.

Can you please check if any windows updates have been applied or any other changes. Yes the issue might also be with your USB drive and you can certainly upgrade the USB drivers to the latest.

Thank you both for commenting. The backup has now stopped. I did plan to pull the USB2 drive and plug it in again. If I get a msg that it could run faster I will reinstall the drivers. I think it thinks is a USB1 device. We will see. This will take some time, I will check back in the morning. Thanks, Keith

Okay, here is the latest: I had a newer USB2 drive and I replaced the former drive. The backup ran very fast but failed early. I am not sure how to award points on this one.

The article in the end of this log is not helpful for my situation.

I awarded points to this Expert because I was having a hardward problem. I now have another problem which I will post as a separate problem.
