Currently backups are handled by Bacula on RamNode. This requires substantial disk space and consequently cost for a service that is thoroughly unmaintained, relatively unused and rarely accessed or required.
We can produce a significant cost saving (up to 75% from rough calculations) if we utilise OVH's Public Cloud Archive service.
Given our backup policy is off-site and off-main provider, this work is unfortunately blocked on us moving away from OVH for our main service hosting.
Currently with database backups, we keep a live copy on the server for menial work (accidental data deletion or recovery of deleted databases) which covers a theoretical 99% of our backup usage needs. We could adopt a similar policy for other bacula backups (except gluster?) and use OVH's PCA to long term store backup snapshots for things like disaster recovery. We need to maintain bacula's recovery period, but we might be able to beat it in some instances.
