Can't restore differential backups in SQL Sever 2012
Posted on 2016-08-22
I have a SQL 2012 server with a maintenance plan that takes full backups daily, differential backups every 3 hours and transaction log backups every hour.
Up until last month, everything was working fine, I could restore any full and differential or transaction log backup to the test server with no issues.
Came back from vacation, and for some reason I can't restore a full + differential backup anymore. Restoring the full backup works fine, or full backup + transaction log back ups works. But if I go to restore, select device and choose both the full and differential backups, normally it would show the Full and Differential backups as two line items, but instead it only shows the Differential, and I can't restore it.
Any ideas on what could cause this?
