We recently powered down a Windows 2008 server for a weekend as the building power supply was being worked on.
Right up until this shutdown, the backups have been happily running daily every day since they were first configured.
Today, we realised that the backups haven't run since the last night before the shutdown, and when we checked the backup scheduler it said there were no backups.
Why would this have happened?
Addendum: I can't be sure that this was the first time we powered down the server since setting up the backups.
