Description

The Restore-AzSqlInstanceDatabase cmdlet restores an instance database from a geo-redundant backup, a point in time in a live database, or a long term retention backup. The restored database is created as a new instance database.

Examples

Example 1: Restore an instance database from a point in time

Restore-AzSqlInstanceDatabase -Name "Database01" -InstanceName "managedInstance1" -ResourceGroupName "ResourceGroup01" -PointInTime UTCDateTime -TargetInstanceDatabaseName "Database01_restored"

The command restores the instance database Database01 from the specified point-in-time backup to the instance database named Database01_restored.

Example 2: Restore an instance database from a point in time to another instance on different resource group

Restore-AzSqlInstanceDatabase -Name "Database01" -InstanceName "managedInstance1" -ResourceGroupName "ResourceGroup01" -PointInTime UTCDateTime -TargetInstanceDatabaseName "Database01_restored" -TargetInstanceName "managedInstance1" -TargetResourceGroupName "ResourceGroup02"

The command restores the instance database Database01 on instance managedInstance1 on resource group ResourceGroup01 from the specified point-in-time backup to the instance database named Database01_restored on instance managedInstance2 on resource group ResourceGroup02.

Example 3: Geo-Restore an instance database

$GeoBackup = Get-AzSqlInstanceDatabaseGeoBackup -ResourceGroupName "ResourceGroup01" -InstanceName "managedInstance1" -Name "Database01"
$GeoBackup | Restore-AzSqlInstanceDatabase -FromGeoBackup -TargetInstanceDatabaseName "Database01_restored" -TargetInstanceName "managedInstance2" -TargetResourceGroupName "ResourceGroup02"

The first command gets the geo-redundant backup for the database named Database01, and then stores it in the $GeoBackup variable. The second command restores the backup in $GeoBackup to the instance database named Database01_restored.

Example 4: Restore a deleted instance database from a point in time

$deletedDatabase = Get-AzSqlDeletedInstanceDatabaseBackup -ResourceGroupName "ResourceGroup01" -InstanceName "managedInstance1" -DatabaseName "DB1"
Restore-AzSqlInstanceDatabase -FromPointInTimeBackup -Name $deletedDatabase.Name -InstanceName $deletedDatabase.ManagedInstanceName -ResourceGroupName $deletedDatabase.ResourceGroupName -DeletionDate $deletedDatabase.DeletionDate -PointInTime UTCDateTime -TargetInstanceDatabaseName "Database01_restored"

The first command gets the deleted instance databases named 'DB1' on Instance 'managedInstance1'. The second command restores the fetched database, from the specified point-in-time backup to the instance database named Database01_restored.

Example 5: Restore a deleted instance database from a point in time

$deletedDatabase = Get-AzSqlDeletedInstanceDatabaseBackup -ResourceGroupName "ResourceGroup01" -InstanceName "managedInstance1" -DatabaseName "DB1"
Restore-AzSqlInstanceDatabase -FromPointInTimeBackup -InputObject $deletedDatabase[0] -PointInTime UTCDateTime -TargetInstanceDatabaseName "Database01_restored"

The first command gets the deleted instance databases named 'DB1' on Instance 'managedInstance1'. The second command restores the fetched database, from the specified point-in-time backup to the instance database named Database01_restored using input object.

Example 6: Restore a database from LTR backup.

Restore-AzSqlInstanceDatabase -FromLongTermRetentionBackup -ResourceId "/subscriptions/f46521f3-5bb0-4eea-a3c2-c2d5987df96b/resourceGroups/testResourceGroup/providers/Microsoft.Sql/locations/southeastasia/longTermRetentionManagedInstances/testInstance/longTermRetentionDatabases/test/longTermRetentionManagedInstanceBackups/15be823c-7e2c-49d8-819f-a3fdcad92215;132268250550000000" -TargetInstanceDatabaseName "restoreTarget" -TargetInstanceName "testInstance" -TargetResourceGroupName "testResourceGroup"

Restores LTR backup with the given resource ID (which can be found by running Get-AzSqlInstanceDatabaseLongTermRetentionBackup).

Example 7. Restore database from different subscription

Restore-AzSqlInstanceDatabase -FromPointInTimeBackup `
			-SubscriptionId "sourceSubscriptionID" `
			-ResourceGroupName "sourceRGName" `
			-InstanceName "sourceManagedInstanceName" `
			-Name "sourceDatabaseName" `
			-PointInTime $pointInTime `
			-TargetInstanceDatabaseName "targetDatabaseName" `
			-TargetInstanceName "targetManagedInstnaceName" `
			-TargetResourceGroupName "targetResourceGroupName" `
			-TargetSubscriptionId "targetSubscriptionId"

The command restores database backup from instance in one subscription to database targetDatabaseName on instance targetManagedInstanceName to different subscription targetSubscriptionId.

Example 8. Restore database from different subscription using source object and pipping

Set-AzContext -SubscriptionId "sourceSubscriptionId"
$sourceDatabase = Get-AzSqlInstanceDatabase -Name "sourceDatabaseName" -InstanceName "sourceManagedInstanceName" -ResourceGroupName "sourceRGName"

Set-AzContext -SubscriptionId "targetSubscriptionId"
$sourceDatabase | Restore-AzSqlInstanceDatabase -FromPointInTimeBackup `
			-PointInTime $pointInTime `
			-TargetInstanceDatabaseName "targetDatabaseName" `
			-TargetInstanceName "targetManagedInstnaceName" `
			-TargetResourceGroupName "targetResourceGroupName" `
			-TargetSubscriptionId "targetSubscriptionId"

First command gets source managed database object and stores in variable sourceDatabase. Second command executes restore from source to the given target database using point in time restore.
