Configure the media retention Server Configuration Option

This topic describes how to configure the media retention server configuration option in SQL Server 2014 by using SQL Server Management Studio or Transact-SQL. The media retention option specifies the length of time to retain each backup set. The option helps protect backups from being overwritten until the specified number of days has elapsed. After you configure media retention option, you do not have to specify the length of time to retain system backups each time you perform a backup. The default value is 0 days, and the maximum value is 365 days.

Limitations and Restrictions

  • If you use the backup medium before the set number of days has passed, SQL Server issues a warning message. SQL Server does not issue a warning unless you change the default.

Recommendations

  • This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.

  • The media retention option can be overridden by using the RETAINDAYS clause of the BACKUP statement.

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.
