SQL Server 2012 Enterprise.
Am currently looking into why backup jobs are taking longer than usual.
Looking through the SQL logs I see the DBs being backed up one by one (I use this to do so - https://ola.hallengren.com/
- so is a single "job")
Looking through I see DB backed up, DB backed up but then I see entries saying Starting up database <dbname> several times and then some more DB backup messages. Then another few start ups and a transaction rollback message (in other words, interspersed between backup notifications are messages that look like a server start up!)
Databases are *not* set to auto close.
Any ideas what could be causing this?
