Backups taking longer and longer

Hi,

We have a customer who has a Windows 2003 SBS server running Backup Exec Version 10.0 Rev. 5520 who has a strange problem their backups keep taking longer and longer to run. they started off taking 9:11 hours to back up 84.8Gb of data and now 4 days later thay are taking 12:37 hours and yet the data has only gone up to 84.9Gb.

The backups run over night and we recently had the tapes and tape drive replaced so the usual cuplrits have gone, the server is fully updated with Windows Updates and there are no real errors in the event log.

Has anyone come across this sort of thing before?

Thanks for any help at all.

    I finally sorted this, what had happened was the UPS had been replaced with a different brand but the software had not been removed so it was running both UPS's software and this was causing the issue.

    I removed the redundant version and everything has returned to normal.

    Is there anything running at the time of the backups? Such as anti-virus software? Either on the source or the media server?

    you need to check which resourse is taking too much of time (you can find that from the job log )
    check if you are backing up any remote server which is too much of time

    Hi,

    As an update this is  a SBS server and is only backing up itself the job rate slows down from 233Mb on the 9 hour backup to 168Mb on the 12 hour one, so far last nights backup has taken over 14 hours and is still 60% of the way through the verify.

    The only scheduled task I can find is for the Shadow Copy, the virus checker was set to do an update at 3am I have now moved this to 10am but apart from that nothing.

    To me it is as if a cache some where is filling up and so the backup is slowing down.

    Thanks

    just check if the removeable storage services is disabled ....as i have seen many time the RSM services caused the backup job to run slow

    Remember that a server w/ a lot of small files can drastically slow you backup

    here we have a server w/ IMSS (Trend)  there is a directory that contains 10.000 small files that server blows my backup windows everyday

    so I put that directory on the exclude list and ZIP that directory to another location.


    problem:
              When you need to restore a single file tat is in the zip file. you will have to restore the ZIP file.

    The trouble is this is a cumaltive slow down over several days. I am trying a reboot tonight to see if this helps at all.
