MySQL semi-sync cluster backups

Last update:

With MySQL semi-sync Managed Databases, backups are created automatically—you don't need to configure or monitor them yourself.

The WAL-G tool is used to create cluster backups. Point-in-Time Recovery is performed using binary log entries (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 day;
  • binlog files are created regularly or when a certain amount of changes have accumulated.

Backup retention period

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

Backups of deleted clusters are stored for 7 days from the moment of creation. From a backup, you can restore the cluster.

Restore cluster

You can restore a cluster from a backup to any point in time within the last 7 days.

When restoring, 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. You cannot change the DBMS type or version.

  1. In the Dashboard, on the top menu click Products and select Managed 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. You will be redirected to the new cluster creation page. Change cluster settings if necessary (see the Create a cluster instructions for details) and click Create cluster.
  6. After the cluster is restored, the node addresses will change—update them in the application that connects to the cluster.
