Mirroring & Database backup

  • If the database is configured to mirroring and what will happen if we select the check the option of verify backup finish and check the integrity of the backup

    Some one mentioned that you can't select that while the db in mirroring

  • Verifying the backup is a good way to allow SQL Server to ensure that the backup file is readable once the backup is complete. I have not heard of any reason that you should not use this on a mirrored environment and cannot think of why reading the backup file metadata would affect the mirror. If you are able to keep verify selected then I would encourage you yo keep using that setting.

  • Running a RESTORE WITH VERIFY_ONLY, which is what the backup validation does, shouldn't interfere with log shipping or anything else on your server.

    It also won't verify that the backup's usable, unless the backup was taken with the CHECKSUM option.

    And even then the only way to have 100% assurance is to run a restore.

    But, it still won't hurt existing databases.
