1. Simple Recovery Model:

As the name recommends, it is a fundamental recovery model that causes the client to restore the full and differential backup. In spite of the fact that this model is anything but difficult to manage, it is reliable just when data isn’t critical. This model may not permit us to restore the database to a given point in time. In this way, the client may possibly restore it to the real-time when the full or differential backup has happened. You may lose any modification done in that term.

Along these lines, this Simple Recovery Model is suggested in the accompanying conditions.

1. If the database is for the development and testing needs only.
2. On the off chance that DBA can manage the cost of the opportunity of losing modification in transactions after the backup.
3. If data isn’t critical and can be recreated when required.

Set Simple Recovery Model for your SQL Server in a simple manner using SQL Server Management Studio with these means:

1. Open SQL Server Management Studio on your computer.
2. Go the client database name and right-click on it. At that point select the Properties alternative.

2. Full Recovery Model

It is a solid model when contrasted with the Simple Recovery Model as it assists with restoring the lost data totally. This model permits point-in-time recovery of the database gave the client has all the substantial database backup alongside value-based Transactional log tail backup.

In the full recovery model, you additionally need to back up transaction log file to avoid its growth

Pick the Full Recovery Model in the accompanying cases.

1. In the event that data is critical, and point-in-recovery is required.
2. You are using Database Mirroring, Always on Availability Groups, and so on
3. In the event that bearing data loss isn’t at all an alternative.

You can set the full recovery model as you have set the straightforward recovery model.

3. Bulk-logged Recovery Model

This model is practically like the full recovery model aside from that it utilizes negligible logging (just data required to recover the transaction is logged). It bolsters point-in-time recovery yet helps in lessening the processing time. Be that as it may, this model is somewhat dangerous as the data may get lost in the logs since the latest backup is damaged. All things considered, changes since the last backup must be revamped.

Choose the Bulk-logged Recovery Model for the accompanying conditions.

1. If you would prefer not to perform bulk operations while using critical data that cannot be lost

2. If insignificant logging is required to decrease more log file development
