  • sbs2003 backup to NAS problems

    Hello,

    i do some support at a small company with 8 users.
    we got a sbs 2003 server i a perimeter network.
    on the inside lan we got a Dell Powerconnect 2724 switch.
    The server, workstations and Promise NS4300N NAS are connected at 1GB speed.
    The NS4300N is a member of AD, so the rights are set with AD groups.

    i set the sbs backup location to the NAS, bud it takes 7 1/2 ours to finish a backup of 38GB, before i had the backup location to a USB-disk, it took about 1 our and 20 min.
    if i copy the backup of 38GB to the NAS by hand, it takes about 50 min, so it looks like it is not the network that gives problems.

    anny sugestions about this problem or were to look for a sollution ?

    Thanks,
    Fred

    Defragment everything just in case,
    turn off the AV
    make sure the server is fully patched and the backup software the same
    make sure you have up to date firmware on everything.
    make sure the server/switch/nas are all set to 1Gbit or 100Full etc.
    run a packet sniffer like wireshark to see what is happening
    any event logs?
    cheers

        Andy,

        thanks for the reply,
        i`am gona set eveything on 1000/full, gona do that next week because i am not gonna do that remote, to big a risk, bud the NAS only supports AUTO settings, cant set it to 1000/full.
        The server and the NAS ar up-to-date with patches and firmware.

        i think i am gona use the sniffer to see if there is somthing wrong.
        the permissions on the NAS are DomainAdmins, full control.

        Thanks

          The service permissions was Mike Shanks' note.

          I would change the network cables as well just in case.
          Please let us know how you get on
          cheers

            Make sure there's nothing else hammering the network while the backup is running.

              Re: sbs2003 backup to NAS problems

              i have the same issue with nss4000 series boxes and the san devices from storage central.

              direct copy is fast but nt backup is 4-8 times slower.
              no change i have made, even putting on the same gigabit switch locally makes any difference.

              i have also tried various reg keys for disk performance in ntbackup and this improved it but not substantially.

              i now do a local backup, then copy the file to the nas device at all sites where i have sufficent room to do so.

              concurrent nas accessing doesnt effect it, (ie ensureing the backup is the ONLY thing being done to the nas)

              i cant give any positive insight but i can confirm a variety of methods that failed to improve the situation and it is the same over multiple nas & san device backup methods when using NTbackup.

                Out of interest, is your test the same, direct copy to NAS of a single file or a backup of the same non-changing file to the same location?

                  Found the Problem on anouther forum,
                  looks like the NTbackup from server 2003 uses a STATFS command that gives the NAS CPU a lot of work, i copiet the NTBACKUP.EXE from a XP station to the server, that doint use the command, bud gives problems with open files and shadowcopy, however this is the problem because the XP NTBACKUP only toke 1.22 hour to backup the information store, it toke the Server 2003 ntbackup 6.40 hour.
                  bud i caint use the XP Ntbackup, because of the errors.
                  looks like i need to use a third party program for the backup

                  Thanxs

                    Very interesting, thanks for posting back.

                    There is an interesting read here too (I realise it is for a specific product but it is still relevant):

                        It gave impressions there was a firmware update that could help, maybe restricting the free space check somehow? I'm only taking from what I read. Can you speak to the manufacturers of your device. I feel it would be beneficial to all if there was a "solution". Please let us know how you get on.
                        cheers
