    Unanswered: Breaking up sql server backups into smaller files

    Hey guys,

    I'm wondering how most people manage very very large backups. What is the best approach to breaking up the backup files if you're restricted to a drive size (450gig in my case). I unix, you can pipe the backup to gzip and split, I'm not sure how the same thing could be accomplished in windows.

    Thanks,
    -Kilka

    Have you looked into backing up filegroups or doing differential backups?
    “If one brings so much courage to this world the world has to kill them or break them, so of course it kills them. The world breaks every one and afterward many are strong at the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry.” Earnest Hemingway, A Farewell To Arms.

    Hey Thrasymachus,

    I had a look and neither of those two would solve the problem. In order to accomplish either of the two, you do need a full backup to recover from scratch. However, after a little investigation, I found out that you can split a full backup into a set of files, I previously never knew you could do this.

    Check this out:
    restore database warehouse_test FROM
    disk = 'X:\warehouse_test1.bak',disk = 'X:\warehouse_test2.bak'

    Peace,
