PostgreSQL PGVector cluster backups

In Cloud Databases PostgreSQL PGVector, cluster backups are created automatically — you do not need to configure them yourself and monitor backup creation.

The WAL-G tool is used to create cluster backups. WAL files are used to perform point-in-time recovery (Point-in-Time Recovery).

Backups are stored in isolation from other users' backups.

Backups cannot be downloaded. Automatic backup creation cannot be disabled.

Backup schedule

  • full cluster backups are created once a week;
  • incremental (delta) backups are created once a day. Such backups contain all changes since the previous backup;
  • WAL files are created every 10 minutes or when a certain volume of changes accumulates.

Backup retention period

Backups are kept for 7 days, after which they are deleted.

Backups of deleted clusters are stored for 7 days from the time the backup was created. You can restore a cluster from a backup.

Restore a cluster

You can restore an existing or deleted cluster from a backup. Restoration is available for any point in time from the last 7 days.

During restoration, a new database cluster is created — you can change the name, configuration (with the same or larger disk size), number of nodes, network, and DBMS settings. The location, DBMS type, and version cannot be changed.

  1. In the control panel, in the top menu, click Products and select Cloud Databases.
  2. Open the Active tab.
  3. In the cluster menu, select Restore.
  4. Select how to restore the cluster—from the last available backup or to a specific point in time within the last 7 days.
  5. Click Continue.
  6. You will be redirected to the page for creating a new cluster. If necessary, change the cluster settings — for details, see the Create cluster instructions.
  7. Click Create cluster.
  8. After the cluster is restored, the node addresses will change; update them in the application that connects to the cluster.
