If you’re doing a health check, run sp_Blitz. The backups don’t necessarily happen exactly on the hour, so developers are left scratching their heads as to why seemingly simple queries suddenly just freeze every now and then for no reason. To make things worse, sysadmins just check boxes in tools like Azure Site Recovery and Veeam and tell them to take backups once an hour. (I’m guessing, based on the blocking storms I’ve been seeing lately, that the backup_start_date and backup_finish_date date/times don’t really correspond to the exact VSS freeze/thaw times.) Finally, they all “finished” at 8:08:10, but even that is a little tricky – in this case, they didn’t all thaw at the exact same time. See how the backup_start_date and backup_finish_date are 40-50 seconds apart? That’s because SQL Server was slowly, gradually stepping through the snapshots of each database. You just find out when your SQL Server suddenly feels like it’s locked up, with tons of blocking issues.įor example, here’s a screenshot from a client’s table when Azure Site Recovery was trying to snapshot hundreds of databases all at once: We recommend that you create a snapshot backup of fewer than 35 databases at the same time.īackup apps like Azure Site Recovery and Veeam don’t warn you about that, though. This can take some time, and while databases are frozen, you’ll see blocking chains for writing queries (which can in turn block readers, too, depending on your isolation level.)īecause of that one-at-a-time problem, KB #943471 says: SQL Server freezes databases one at a time, serially, until it’s got them all frozen. It sounds like witchcraft, but it really does work, and it’s worked for years.

These snapshot backups show up in system tables like because when used successfully, they’re like full backups.

To pull it off, they use the Windows Volume Shadow Copy Service to do snapshot backups – often referred to as VSS snaps. They let you quickly replicate a virtual machine to somewhere else without knowing too much about the server’s contents.
