Re: Backup of databases on OpenShift

Title: Re: Backup of databases on OpenShift
Hi Jens.

We recently set up an OpenShift Enterprise cloud and we're wondering what the best practices are for backing up databases running in an OpenShift cloud. I will focus on PostgreSQL here, but the same goes for MongoDB, MariaDB...

- Should we rely on backups of the persistent volumes (we're using NFS)? This would mean assuming the on-disk state is always recoverable. Which it *should* be, but it does feel like a hack...
- Should we have an admin-level oc script that filters out all running database containers and does some 'oc exec pg_dump ... > backup.sql' magic on them?
- Should we provide some simple templates to our users that contain nothing but a cron script that calls pg_dump?

Please share your solutions?

I like this one.

oc rsh <POD> mysqldump/pg_dump/... > backup_file

Some user use Filesytem back, as you have mentioned

I have seen somewhere out a concept with a sidecar container but I can't find it now

What I have seen in the past is not the backup the problem, the restore is the difficult part.
I have once needed to restore a db (postgresql) and it was not that easy and not automatically!

Kind Regards,
