Protect All Forms of Data With An SQL Backup

When using an SQL backup program, you will discover it provides three different database recovery methods. They all have similarities in how they protect information, but they also have differences. The one you use depends on the importance of the data and what would happen if it was lost. It isn't uncommon to have different levels in your business. For instance, financial data or special formulas would be classified as top secret and extremely important. You also wouldn't want client information leaking out.

The basic recovery method is the simple model, as data is only recovered according to the differential backup or the most recent full backup. Unfortunately, the incremental changes or the transaction log backups won't be available in this method, but it is easier to manage. Most people can maneuver themselves around this option, but if disaster would strike, your data isn't as protected as other methods. You could lose more database transaction log information, even when a check point is provided. This would be the kind of SQL backup you would use for low priority information.

A full backup method makes sure to copy transaction logs and database backups. It saves everything, providing full protection against disaster. If even one data file is damaged, the backup will recover all committed files and transactions using the transaction log backups and what is on the databases. This recovery method will provide the ability to recover everything right up to the time of failure or a specific time. You will be able to recover all data, even the Create Index, Select Into, and bulk loading data.

If you use the bulk-logged model, you receive the best protection and performance. However, not everything can be recovered. This is why you must choose between the methods, going according to the data's importance.
