This page provides an overview of data backup and restore solutions available to
AlloyDB Omni database clusters.
Because AlloyDB Omni is PostgreSQL compatible, various backup
solutions developed and supported by the PostgreSQL community are also available
to AlloyDB Omni databases. Any solution that lets you back up
from and restore to a PostgreSQL cluster running in a Docker or Podman container
also works with AlloyDB Omni.
Single-server backup solutions
If you run AlloyDB Omni in a container on individual servers, we
recommend you use pgBackRest. pgBackRest performs
physical database cluster backups.
pgBackRest has the following distinct features:
Perform full, incremental, or differential backups
Write to local disk, remote disk, or cloud storage destinations
Parallelize and encrypt backups
Compression and checksums (done in-stream) options
Automatic management and expiration of backups
The AlloyDB Omni container includes the pgBackRest utility, which
lets you perform the following tasks:
Perform physical backups and restorations of your database clusters.
Build clone clusters, either to a current or to a specific point in time.
Perform selective restores of specific databases from within your database
cluster.
If you have deployed AlloyDB Omni onto a Kubernetes cluster, then
the AlloyDB Omni operator provides backup and restore methods without the
need for any further configuration.
