Recovery Model Changes

  • I have a couple fairly large (5.25 GB +-) databases that are currently set up with a simple recovery model. 

    I would like to change to a full recovery model so we can do transaction log backups throughout the day rather than just a nightly backup. 

    Can anyone think of a problem with just changing from simple to full?  I always just create databases with a full recovery model when I know they are going to get big.  I've never tried changing recovery models once the database is created.

    Thanks muchly,

  • Not sure what your concern is but it's not a problem to change it, go for it.

  • Changing it is no problem. Just remember to schedule transaction log backups. (And 5.25 GB isn't a large database in SQL Server - my main database is currently over 200 GB).

    At one point my main database was around 300GB and I had to change it from FULL to SIMPLE and back to FULL again in one day. I didn't have any problems. The thing I had to remember (since I went from full to simple and back) was that going to SIMPLE broke my log backup chain, so once I went back to full mode I had to do a full backup.
