Restore a PostgreSQL Cluster

With IONOS DBaaS, you may roll back your PostgreSQL clusters to a previous point in time or use it to create a new cluster. This reliable function prevents data loss and downtime in unexpected situations.

For example, consider that certain values were accidentally deleted from your cluster around 11 hours today. The easiest way to recover missing data is to restore a backup before 11 hours.

Note: You can restore only one backup at a time, and you must wait for the restoration process to finish before restoring another backup.

Prerequisites:

  • The backup must belong to the PostgreSQL cluster to be restored.

  • The cluster must be in the AVAILABLE state.

To restore a cluster, follow these steps:

1. In the DCD, go to Menu > Databases > PostgreSQL.

2. Select a cluster from the list by clicking on its name. Alternatively, click Details in the OPTIONS column.
