About backups¶

You can backup your data in two ways:

On-demand. You can do them manually at any moment.
Scheduled backups. Configure backups and their schedule in the deploy/cr.yaml . The Operator makes them automatically according to the specified schedule.

To make backups and restores, the Operator uses the Percona Backup for MongoDB tool.

Backup storage¶

You can store Percona Server for MongoDB backups outside the Kubernetes cluster using the following remote backup storages:

Backup types¶

The Operator can do either logical or physical backups.

Logical backup means querying the Percona Server for MongoDB for the database data and writing the retrieved data to the remote backup storage.
Physical backup means copying physical files from the Percona Server for MongoDB dbPath data directory to the remote backup storage.

Logical backups use less storage, but are much slower than physical backup/restore.

Warning

Logical backups made with the Operator versions before 1.9.0 are incompatible for restore with the Operator 1.9.0 and later. That is because Percona Backup for MongoDB 1.5.0 used by the newer Operator versions processes system collections Users and Roles differently . The recommended approach is to make a fresh backup after upgrading the Operator to version 1.9.0.
