I have a SQL Server 2012 database. It has no more than 6 users. I want to have a backup that allows to restore to a point in time with not more than 15 minutes of data loss.
I am considering automating it as such: Full back up each day at 2 AM, a differential backup each hour, and a Transaction Log backup every 15 minutes.
Quesiton:
1. Does this seem reasonable?
2. After each new Full back up should I set a cleanup task to remove previous days backups (full/differential/log) so that I don’t end up with endless number of files and danger of filling the whole drive?
