Time for backup increases significantly suddenly RRS feed

  • Question

  • Dear Sir,
     
    Since some weeks the time necessary for a backup of my system (automatic) increased from about 18 minutes to over 2 hours and 20 minutes.  The backup cocnist of multiple disks. However no hardware or setting changes in this system, nor changes in the server.
    What are the things to look for.
    I use the server for almost a year and no problems at all so far.
     
    Harddisk space of about 75% available on the server.
     
    Thanks for your attention.
    Kind regards,
    Ben van Beek

  • I reinstalled WHS on the server and everything is back to normal. I performed a complete new install including the drivers for the motherboard etc.
    Thanks for all replies. Backups are running smoothly again.

  • Hi, Ben.  I had the same issue with two of my laptops -- seems something the users downloaded corrupted some files in the basic system area (don't know/don't care which ones), so I did a repair reinstallation of Windows and the backup times went right back down to where they were before.  Don't know if that would work for you, but it has worked -- twice -- for me.

    files are shared, workstations are backed up (and occasionally restored) and life goes on...

    Does it happen on only 1 client, or all of them (assuming you have more than 1)?

  • Hi,
    does a defragmentation happen on that system very often? This may lead to increasd times for validating the changed clusters.
    Is the network connection still 1 GBit/s or whatever it was on both ends of the connection? Sometimes Windows Server may reduce the speed, if the connection quality is determined as too bad (cable, plugs, all on the way can play a role).

  • Hello, thanks for the responses.
    It happens on all clients. I need to check the cable connection however that is very short but anyway. The message on the progress pane of the backup from WHS is that the sever is rearranging the data on the server during the backup, this takes during each backup for each drive an enormous amount of time.
    Any further ideas?

    Since it's on all clients, I would assume it's a problem with your server.  For starters, have you tried running chkdsk on your server hard drives?  If not, you could start with that.  Please see the FAQ post:  How to check all the drives in your server for errors for details on how to do that.

    I've got the same problem that started about a week ago Backups that were taking 20 minutes to maybe an hour now take 2-7 hours. All client backups are extermely slow, and it's the "rearranging data on server" that takes forever.

    I'll run chkdsk this weekend as the problem may have occured when I had a power loss to the server (i.e. a no graceful shutdown).
