Back and restore

  • SQL version 2k

    After creating a full backup file and then appending incrementals to it, one of the incrementals fail in the middle of execution. Is the backup file still good? or has this failure corrupted the entire backup file?

    Thanks in advance for any help on this...

  • You can try a RESTORE VERIFYONLY on the file, but I would suggest restoring the full and incrementals on a test server as this would be the best way to know for sure.

  • Thanks for your reply, and yes, that would verify this one, but I have many Db backups and from time to time there will be a failure. What I would like to know is when a failure accures as mensioned above: (1) the backup is bad (2) the backup is fine (3) unknow without testing.

     

  • It would be great if you knew for sure that it was a good or bad backup; however, all backups would fall into your #3 category.  One never truely knows the validity of a backup witout attempting a restore.  I would recommend periodically testing your backup files by restoring as this is the only way to ever know for sure that your backups are good.

  • You can verify the the integrity of the database backup once the backup is complete. This can be done with choosing verify the intgrity of backup after completion if done through enterprise manager or using restore verifyonly with tsql.
