Time for my daily stupid SQL question!
We currently have 3 backup schedules on SQL Server 2012:
- Full backup at 10pm
- Full backup at 7am
- Transaction backups between 7:30 & 20:00
The full backups all run at around 22GB, as does the first transaction backup of the day. Every transaction backup after that runs at around 70-100MB per 30 mins.
To my mind, the first transaction backup should be tiny. Pretty much nothing happens between 7:00 & 7:30.
It seems that it's not taking into account that we're taking a full backup at 7:00, and is instead doing a transaction backup for everything that's happened since 20:00 the previous night.
Is there any way to confirm that?
