Tool: restore_cluster
Restores an AlloyDB cluster from a given backup or a source cluster and a timestamp.
Requirements
- Depending on the source type, the requirements are different.
- For a backup source, the backup resource must exist. The backup resource can be created on-demand or from an automated system.
- For a continuous backup (also known as PITR) source, the source cluster must exist and have continuous backup enabled.
- For a backup and disaster recovery source, the backup resource must exist inside the backup vault.
- For a backup and disaster recovery point in time recovery source, the data source must exist inside the backup vault.
Usage
- Call
create_backupto create an on-demand backup if needed. - Call
restore_clusterto restore a cluster from a given backup or a source cluster and a timestamp. - This will return a long-running operation that indicates the progress of the cluster restoration. The time taken for the operation to complete depends on the size of the backup or the source cluster.
- You can poll the status of the operation using the
get_operationtool. - Once the long-running operation is complete, the new cluster will be in a READY state.
