good evening,
i was reading about rados dropping support for ceph plugin
(https://www.bareos.com/bareos-22-release/), this means that i cannot do
anymore backup of ceph rbd based vms (for example openstack)?
As most Ceph applications (like RBD) require special precautions and
knowledge of what data you're handling, there is no real use-case for
backing up raw RADOS objects. Thus we decided to remove it.
Essentially you could never sanely back up RBDs with that plugin. Wheter
or not you're actually able to restore a consistent state is mostly pure
luck.
To properly back up an RBD, one would need to implement RBD Incremental
Backup https://docs.ceph.com/en/latest/dev/rbd-diff/ which can probably
be done in a rather simple python plugin.
Best Regards,
Andreas
