# MySQL sync cluster backups

In MySQL sync Managed Databases, cluster backups are created automatically—you do not need to configure them yourself or keep track of backup creation.

The WAL-G tool is used to create cluster backups. Point-in-Time Recovery is performed using binary log entries.

Backups are stored in isolation from other users' backups.

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

## Backup schedule \{#backup-schedule}

* full cluster backups are created once a day;
* binlog files are created regularly or as a certain volume of changes accumulates.

## Backup retention period \{#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 a cluster](#restore-cluster).

## Restore cluster \{#restore-cluster}

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

Restoration creates a new database cluster; 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.
