    Default backup netapp NDMP node with TSM...failure

    TSM rel. 6.2.2

    Pro’s,

    I try to backup a part of a netapp (nearstore) volume with TSM NDMP. The volume is 6 TB and the actual data size of the volume is 700 GB. The problem I have is that the backup process now have backed up over 10 TB of data. How can this be possible?
    If I check the volumes that TSM have used so far, there are no qontent on the volumes. Does anyone know how NDMP backup from a netapp works and shall be setup? Below you can see how I’ve setup my site…

    Hi,

    Somehow... the volume I ran the backup command on has increased dramatically since I started the backup. I think I was little bit to quick to post this question...

    But I have one remaining question:
    Why can't I see any data when I type "q cont VOLNAME" ? Does the backup need to finish before I se the data on the allocated tapes?

    Output from my netapp:

    storry*> df -h storry_sbd_vol1
    Filesystem total used avail capacity Mounted on
    /vol/storry_sbd_vol1/ 6144GB 4805GB 1338GB 78% /vol/storry_sbd_vol1/
    /vol/storry_sbd_vol1/.snapshot 0GB 483GB 0GB ---% /vol/storry_sbd_vol1/.snapshot
    storry*> df -sh storry_sbd_vol1
    Filesystem used saved %saved
    /vol/storry_sbd_vol1/ 4805GB 7191GB 60%

    Hi,

    from the output you provided it is obvious - you are using deduplication, so the volume is 6TB in size, but contains 4805+7191=11996GB.
    Yes, backup of the given object (in any backup/archive mode) must be completed before it appears in "q content".

    In a case of a complete restore you have to have a 12TB+ volume available.

    friend,

    The first is FULL NDMP backup, the total size allocated on the server, not used. If you have only 6 TB allocated it will not do 10 TB backup, use the command "q fi storry.xxx / orabackup" to know the actual size allocated.
