SQL recovery model for ADFS deployment
SIMPLE or FULL recovery model for databases?Sql Server 2008 R2: Simple recovery model with transaction log backupsBacking up SQL Server 2008 database in different recovery modelSIMPLE or FULL recovery model for databases?Is bulk-logged recovery model ever a good choice if point-in-time restore is not needed?Switching from SIMPLE to FULL recovery mode implicationsWhich Log should I start backups with?Concurrent backups (full and transaction) and testing recovery modelAre non 'copy-only' full backups safe to recover from?Setting DB to Simple Recovery then back to Full RecoveryFull backup of Simple recovery model - how much log is backed up if there is an open transaction
We have "AdfsConfiguration" and "AdfsArtifactStore" databases for our ADFS deployment. I keep running into disk space issues due to the full and transaction log backups being taken on the server.
Right now, these two databases are in Full recovery model - but I wonder if I can just switch to Simple. Are transaction log backups going to be important in these two databases?
I have searched a lot but can't really understand whether these DBs need actually need the trans log backups or if just a nightly full backup is good enough.
Also, I understand the general rules of thumb for deciding between the two models (SIMPLE or FULL recovery model for databases?) for I just can't come to and understand on what these ADFS databases are really doing to make the decision.
This is a screenshot of the "restore" GUI screen. it shows how I have log backups taken every 30 min:
This basically means our RPO is 30 min? And then the full backup ensures ALL previous transactions are recoverable if they occurred before it was taken (in other words... I don't need to have log backup files from before the point in time in which the full backup was taken, right?)
I am not using compression (only available in Enterprise Edition right?)
I have thought about daily DIFFs and weekly FULLs. I honestly just seem to read online of a lot of people doing nightly FULLs. All instances I inherited were already set up to do nightly FULLs and I haven't seen any that do daily DIFFs (not that this means I shouldn't make a change of course).
Honestly I'm one of those "accidental" DBAs (am more of a developer). It's been overwhelming to actually try to get up to speed on everything I need to understand and put into practice.

On another topic, hopefully you are running DBCC CHECKDB commands against these databases on a frequent basis so you can be proactive in catching any kind of corruption early enough.

When ADFS is installed using the built-in Windows Information Database (which runs an embedded SQL Server on the AD DC), these databases are installed in SIMPLE recovery model. You could possibly take that as an indication that it would be OK to run them in SIMPLE model in your own environment, but that is up to you.
In general, if you're taking a full SQL backup daily, you should be OK discarding any historical transaction log backups prior to the full backup to save on disk space. But this depends on your need to be able to restore the database to any point in time in the past. If your policy requires you to be able to restore the database to a specific point in time, then you'll likely need to hang onto all those full, diff, and tlog backups that comprise your RPO.
