Different Parts of an SQL Backup Program

This is why anyone who regularly uses a database should have an SQL backup program in place. There are several options available, but make sure a dependable recovery plan is chosen just in case data corruption or system failure takes place.

For one, you need to pick a recovery model that works for you. Whether it is the simple mode that backs up everything recent or the full backup that saves the transaction log and creates a complete database backup, there are options. Once you decide on the method that works best for you, it is important to decide how the backup options should be configured. These are things like the Enterprise Manager, T-SQL commands, or Maintenance Plan Wizard.

If you mainly use the database method, this is guaranteed to create full copies of the database, which means a complete snapshot of everything at that time. You will receive a copy of the active log, which works in conjunction with the database backup. Whenever successive logs become created, you will receive a new set of transactions.

The differential method will only copy the pages of the database that have been changed since the previous backup. If successive ones are saved, you will get the most recent copy. This is good to use with a full backup, which is helpful because you won't have to do a complete backup each time.

When thinking about using an SQL backup program, there are a lot of things to consider. However, many believe it is guaranteed to protect your data.
