Option to restore from another cluster's backup

[aleredzz]

Proposal

I came across the restore into a new cluster feature of the PBM here: https://docs.percona.com/percona-backup-mongodb/features/restore-new-env.html

However the same feature is not present in the docs for the Mongo operator
https://docs.percona.com/percona-operator-for-mongodb/

I found out you can force a resync with the backend storage with pbm config --force-resync on the PBM agent running in the cluster. However after trying to restore with pbm restore my cluster was quite unstable with many mongos and cfg and rs pods being unavailable. My cluster was heavily provisioned but still faced the issue. I tired this with a logical backup.

An idea could be:

kind: PerconaServerMongoDBRestore
apiVersion: psmdb.percona.com/v1
metadata:
  name: manual-restore-operation
spec:
  clusterName: mongo-cluster
  backupName: backup-from-another-cluster
  backupSource: external

with backupSource indicating that the backup is not in the perconaservermongodbbackup list but forcing a resync with storage backend.

I this is a use case already covered by any other method, please refer me to it (maybe physical backups and restores)

Thanks

Is this a feature you are interested in implementing yourself?

Maybe

Anything else?

Hi @aleredzz we your backupSource option is wrong, please check this file https://github.com/percona/percona-server-mongodb-operator/blob/main/deploy/backup/restore.yaml#L15

All these options are documented https://docs.percona.com/percona-operator-for-mongodb/restore-options.html#the-backupsource-subsection and we have a doc how to use it https://docs.percona.com/percona-operator-for-mongodb/backups-restore-to-new-cluster.html#without-point-in-time-recovery

Hi @aleredzz does it work for you?

Hi @hors, Thank you so much for the follow up.
The backupSource I put there was a proposal for a solution - since I could not make it work.
I will try it soon and let you know how it goes.
Thanks
