If I do :
- a full backup on Monday at 9am
- a differential backup on Tuesday at 9am
- a differential backup on Wednesday at 9am
- a differential backup on Thursday at 9am
- a differential backup on Friday at 9am and a Transaction Log backup at 9:30am and every 39 mins after that.
Say my database fails at 10:01am
Why do I have to restore the Full back from Monday and the Differential backup from Friday and all Trans log backups as opposed to the Full back from Monday and all Trans log backups i.e. why do I need to restore the latest Diff backup also? The full backup
has the translog changes and my first trans log backup on Friday at 9:30am has all changes to the trans log since the full backup? So why must I restore the latest Diff backup before restoring all the trans log backups?
