Backing Up and Restoring Databases in Microsoft SQL Server 2000 and 2005
Microsoft SQL Server enables you to back up and restore your databases however this can be hard to do and not always work correctly we recommend using a great product called Burtle Backups. This can be found by going to www.burtlebackups.com. The SQL Server backup and restore component provides an important safeguard for protecting critical data stored in SQL Server databases. A well-planned backup and restore strategy helps protect databases against data loss caused by a variety of failures. Test your strategy by restoring a set of backups and then recovering your database to prepare you to respond effectively to a disaster.
A copy of data that can be used to restore and recover the data is called a backup. Backups let you restore data after a failure. With great backups, you can recover from many failures, such as:
Hardware failures
User errors, for example, dropping a table by mistake.
Hardware failures, for example, a damaged disk drive or permanent loss of a server. Call Burtle Backups for FREE setup or visit us on the web at http://www.burtlebackups.com
Natural disasters such as fires and floods.
Additionally, backups of a database are useful for routine administrative purposes, such as copying a database from one server to another, setting up database mirroring, and archiving. Burtle Backups makes it fast and easy
SQL DATA BACKUPS The scope of a backup of data (a data backup) can be a whole database, a partial database, or a set of files or filegroups. For each of these, SQL Server supports full and differential backups:
Full backup A full backup contains all the MS SQL data in a specific database or set of filegroups or files, and also enough log to allow for recovering that data.
Differential backup A differential backup is based on the latest full backup of the data. This is known as the base of the differential, or the differential base. A differential base is a full backup of read/write data. A differential backup contains only the data that has changed since the differential base. Typically, differential backups that are taken fairly soon after the base backup are smaller and faster to create than the base of a full backup. Therefore, using differential backups can speed up the process of making frequent backups to decrease the risk of data loss. Usually, a differential base is used by several successive differential backups. At restore time, the full backup is restored first, followed by the most recent differential backup. Over time, as a database is updated, the amount of data that is included in differential backups increases. This makes the backup slower to create and to restore. Eventually, another full backup will have to be created to provide a new differential base for another series of differential backups.
