Backing up microsoft sql server


















Ownership and permission problems on the backup device's physical file can interfere with a backup operation. The SQL Server service should read and write to the device. The account under which the SQL Server service runs must have write permissions to the backup device.

Problems in the backup device's physical file may not appear until the backup is used or a restore attempted. Expand Databases , and either select a user database or expand System Databases and select a system database. Right-click the database that you wish to backup, point to Tasks , and then select Back Up In the Back Up Database dialog box, the database that you selected appears in the drop-down list which you can change to any other database on the server.

In the Backup type drop-down list, select a backup type - the default is Full. You must perform at least one full database backup before you can perform a differential or a transaction log backup. In the Destination section, review the default location for the backup file in the..

You can use the Back up to drop-down list to select a different device. Select Add to add backup objects and or destinations. You can stripe the backup set across multiple files for increased backup speed. To remove a backup destination, select it and select Remove. To view the contents of an existing backup destination, select it and select Contents. For more information about the various backup options, see General page , Media options page , and Backup options page. After creating a full database backup, you can create a differential database backup or a transaction log backup.

A copy-only backup isn't available for the Differential backup type. On the General page in the Destination section select Disk from the Back up to: drop-down list. Select Add and the Select Backup Destination dialog box will open. Enter a valid path and file name in the File name text box and use. Yes, Comet allows customizable backup scheduling.

We also have 9 customizable retention range policies to choose from and customizable email reporting. Yes, you can run multiple backups on the same machine at the same time. After adding your protected devices, you can choose additional boosters, such as Microsoft SQL. Calculate your monthly usage with our Backup Cost Calculator. Additionally, for the given tape drive, we recommend that you use only tapes recommended by the drive manufacturer.

For more information about how to install a tape drive, see the documentation for the Windows operating system. When a tape drive is used, a backup operation may fill one tape and continue onto another tape.

Each tape contains a media header. The first media used is called the initial tape. Each successive tape is known as a continuation tape and has a media sequence number that is one higher than the previous tape.

For example, a media set associated with four tape devices contains at least four initial tapes and, if the database does not fit, four series of continuation tapes. When appending a backup set, you must mount the last tape in the series. If the last tape is not mounted, the Database Engine scans forward to the end of the mounted tape and then requires that you change the tape. At that point, mount the last tape. The tape device must be connected physically to the computer that is running an instance of SQL Server.

Backing up to remote tape devices is not supported. If a tape backup device is filled during the backup operation, but more data still must be written, SQL Server prompts for a new tape and continues the backup operation after a new tape is loaded.

You can control whether a backup tape is unloaded automatically from the tape drive after a backup or restore operation.

You can control whether SQL Server keeps the tape remains open after the backup or restore operation or releases and rewinds the tape after it fills. To view a list of open tape devices and the status of mount requests, query the sys. This view shows all the open tapes. A logical backup device is an optional, user-defined name that points to a specific physical backup device a disk file or tape drive. A logical backup device lets you use indirection when referencing the corresponding physical backup device.

Defining a logical backup device involves assigning a logical name to a physical device. The logical device name must be unique among all the logical backup devices on the server instance. To view the existing logical device names, query the sys. This view displays the name of each logical backup device and describes the type and physical file name or path of the corresponding physical backup device.

For example, the following statement backs up the AdventureWorks database to the AdventureWorksBackups logical backup device. One advantage of using a logical backup device is that it is simpler to use than a long path. Using a logical backup device can help if you plan to write a series of backups to the same path or to a tape device. Logical backup devices are especially useful for identifying tape backup devices.

A backup script can be written to use a particular logical backup device. This lets you switch to a new physical backup devices without updating the script.
