Working with Recovery Models: SIMPLE

Hi experts:

I understand about Recovery Models: SIMPLE
1. Does not permit or require log backups
2. Automatically truncates log to keep space requirements small

in that case I set it up? when should I use it?

Sorry I am not understanding the question. . Simple Mode is what I am mostly used to. From my experience most production systems if they are supporting a major company application Full may be best practice but that may depend on resources as well.

First off, for your reference, make sure to read the docs on this: https://msdn.microsoft.com/en-us/library/ms189275.aspx

When you run in Simple recovery mode, you lose the ability to perform a point in time recovery.  The only option you have for recovery in the event of a disaster is going back to your last full or differential backup.

Full recovery mode allows you to perform a backup (ideally) right up to the point of failure.

I always run my production databases in full recovery mode with regular transaction log backups.

When to use Simple?  I use simple on anything that's not production (Dev, Test, Training).

If you need the ability to recover from a failure to as close to the point of failure as possible, then you better be in Full recovery mode.

As been said, Simple recovery model only allows Full and Differential backups. Doesn't allow a recover in point.
When to use it? When the business doesn't requires a recover in point solution. Mostly this is for non Production databases but even in Production environment you can have databases with Simple Recovery mode, mostly databases that are feed from other sources so you can recover the data by running the import process again.
The bad side from Full Recovery mode is the need for more disk space and that's why you need to chose wisely between Full and Simple recovery mode.
