Description

The Set-AzSqlDatabaseBackupShortTermRetentionPolicy cmdlet sets the short term retention policy for this database. The policy is the retention period, in days, for point-in-time restore backups and differential backup frequency, in hours.

Examples

Example 1

Set-AzSqlDatabaseBackupShortTermRetentionPolicy -ResourceGroupName resourcegroup01 -ServerName server01 -DatabaseName database01 -RetentionDays 6 -DiffBackupIntervalInHours 24

ResourceGroupName ServerName DatabaseName RetentionDays DiffBackupIntervalInHours
----------------- ---------- ------------ ------------- -------------------------
resourcegroup01   server01   database01   6             24

This command sets the short term retention policy for database01 to 6 retention days and 24 differential backup interval hours.

Example 2

Get-AzSqlDatabase -ResourceGroupName resourcegroup01 -ServerName server01 -DatabaseName database01 | Set-AzSqlDatabaseBackupShortTermRetentionPolicy -RetentionDays 5 -DiffBackupIntervalInHours 12

ResourceGroupName ServerName DatabaseName RetentionDays DiffBackupIntervalInHours
----------------- ---------- ------------ ------------- ------------------------
resourcegroup01   server01   database01   5             12

This command sets the short term retention policy for database01 to 5 retention days and 12 differential backup interval hours via piping in a database object.

Example 3

Set-AzSqlDatabaseBackupShortTermRetentionPolicy -ResourceGroupName resourcegroup01 -ServerName server01 -DatabaseName database01 -RetentionDays 7

ResourceGroupName ServerName DatabaseName RetentionDays DiffBackupIntervalInHours
----------------- ---------- ------------ ------------- -------------------------
resourcegroup01   server01   database01   7             12

This command sets the short term retention policy for database01 to 7 retention days only. DiffBackupIntervalInHours is unchanged.
