View or Configure the backup compression default Server Configuration Option

This topic describes how to view or configure the backup compression default server configuration option in SQL Server 2014 by using SQL Server Management Studio or Transact-SQL. The backup compression default option determines whether the server instance creates compressed backups by default. When SQL Server is installed, the backup compression default option is off.

Limitations and Restrictions

Recommendations

  • When you are creating an individual backup, configuring a log shipping configuration, or creating a maintenance plan, you can override the server-level default.

  • Backup compression is supported for both disk backup devices and tape backup devices.

Security

Permissions

Execute permissions on sp_configure with no parameters or with only the first parameter are granted to all users by default. To execute sp_configure with both parameters to change a configuration option or to run the RECONFIGURE statement, a user must be granted the ALTER SETTINGS server-level permission. The ALTER SETTINGS permission is implicitly held by the sysadmin and serveradmin fixed server roles.

To view or configure the backup compression default option

  1. In Object Explorer, right-click a server and select Properties.

  2. Click the Database settings node.

  3. Under Backup and restore, Compress backup shows the current setting of the backup compression default option. This setting determines the server-level default for compressing backups, as follows:

    • If the Compress backup box is blank, new backups are uncompressed by default.

    • If the Compress backup box is checked, new backups are compressed by default.

    If you are a member of the sysadmin or serveradmin fixed server role, you can also change the default setting by clicking the Compress backup box.
