  • Cikk

Applies to: SQL Server 2016 (13.x) and later versions

Configures automated or custom scheduling options for SQL Server managed backup to Microsoft Azure.

Transact-SQL syntax conventions

Syntax

EXEC managed_backup.sp_backup_config_schedule
    [ @database_name = ] 'database_name'
    , [ @scheduling_option = ] { 'Custom' | 'System' }
    , [ @full_backup_freq_type = ] { 'Daily' | 'Weekly' }
    , [ @days_of_week = ] 'days_of_the_week'
    , [ @backup_begin_time = ] 'begin time of the backup window'
    , [ @backup_duration = ] 'backup window length'
    , [ @log_backup_freq = ] 'frequency of log backup'
[ ; ]

Arguments

[ @database_name = ] 'database_name'

The database name for enabling managed backup on a specific database.

If @database_name is set to NULL, the settings are applied at instance level (applies to all new databases created on the instance).

[ @scheduling_option = ] { 'Custom' | 'System' }

Specify System for system-controlled backup scheduling. Specify Custom for a custom schedule defined by the other parameters.

[ @full_backup_freq_type = ] { 'Daily' | 'Weekly' }

The frequency type for the managed backup operation, which can be set to Daily or Weekly.

[ @days_of_week = ] 'days_of_the_week'

The days of the week for the backups when @full_backup_freq_type is set to Weekly. Specify full string names like Monday. You can also specify more than one day name, separated by the pipe symbol (|). For example, N'Monday | Wednesday | Friday'.

[ @backup_begin_time = ] 'begin time of the backup window'

The start time of the backup window. Backups aren't started outside of the time window, which is defined by a combination of @backup_begin_time and @backup_duration. Format: hh:mm.

[ @backup_duration = ] 'backup window length'

The duration of the backup time window. There's no guarantee that backups will be completed during the time window defined by @backup_begin_time and @backup_duration. Backup operations that are started in this time window but exceed the duration of the window won't be canceled. Format: hh:mm.

[ @log_backup_freq = ] 'frequency of log backup'

This determines the frequency of transaction log backups. These backups happen at regular intervals rather than on the schedule specified for the database backups. @log_backup_freq can be in minutes or hours and 0:00 is valid, which indicates no log backups. Disabling log backups would only be appropriate for databases with a simple recovery model. Format: hh:mm.

Note

If the recovery model changes from simple to full, you need to reconfigure the @log_backup_freq from 0:00 to a non-zero value.

Return code values

0 (success) or 1 (failure).

Permissions

Requires membership in the db_backupoperator database role, with ALTER ANY CREDENTIAL permissions, and EXECUTE permissions on the sp_delete_backuphistory stored procedure.

Examples

The following example configures managed backups for database Test, performing daily full backups beginning at 4am, with a maximum backup duration of 2 hours, and log frequency of 15 minutes.

USE msdb;
GO

EXEC managed_backup.sp_backup_config_schedule @database_name = 'Test',
    @scheduling_option = 'Custom',
    @full_backup_freq_type = 'Daily',
    @backup_begin_time = '04:00',
    @backup_duration = '02:00',
    @log_backup_freq = '00:15';
GO
