[DISCUSS] Disaster Recovery solution for CloudStack
Hi forks,
I'm looking for a Disaster Recovery solution on CS. Looking around I found
an article showing some great informations but not enought. Personally I
think:
+ Host: CS already implemented migration, which can move VMs to another
pearful host
+ Database: we have replication
+ Management Server: we can use multi MS
+ Primary Storage: it's the important component when Disaster Recovery
happen. It contains ROOT and DATA volumes and nobody happy if they're lost.
We need mirror (or replicate) solution here. Many distribute file system
can help (GlusterFS, Ceph, Hadoop..). An interesting solution I found on
XenServer is Portable SR, which make the SR become fully self-contained. We
can detach it and re-attach to a new host. Nothing lost.
+ Secondary Storage: Easy to backup.
How do you think? Did you have a plan to do Disaster Recovery?
Thanks,

Replication is not enough. Your database with CloudStack is key, it's
your most precious metadata, so make sure you have GOOD, very good
backups of it.
The best would be a dump of the database every X hours and have binary
logs as well to be able to go into into point in time with your database.

CloudStack can't tell you anything about how safe the data is on your
primary storage, so you just want to make sure you never loose data on it.
Ceph is a great example (I'm a big time fan!) of how you can store your
data on multiple machines. But even when not using Ceph, just make sure
you don't loose data on it.
ZFS with zfs send|receive is a great way to backup your data to a
secondary location in case something goes wrong and you need to restore.
