I just created a new post when I became aware of this one…
I am using “Windows Components” to backup a number of SQL Server databases.
A couple of weeks ago I tried restoring a database using the “Restore Components” feature.
I first deleted the DB
restored the appropriate DB from the “components” and re-attached the DB
(!) received an error about Urbackup not being able to replace some file, asking to reboot(!)
Since I couldn’t just restart at that time it took another four weeks until I rebooted the server (ever since receiving the request for reboot).
After rebooting MOST OF MY PRODUCTION DATABASES WERE GONE!!!
Only the restored DB and another DB created in the past four weeks still existed after the reboot.
I would assume that Urbackup rolled back some VSS snapshot and made all other DBs disappear.
Luckily I had backups of the DBs in question but it was a very scary experience nonetheless.
