Hello,
Does someone know any tool/method to replicate the VMS from a "Production"
Cluster to "Secondary" Cluster, to provide a DR solution without Storage
replication dependency or Gluster Storage.
Like Veeam, Zerto toosl do with other hypervisors.
Is there anyway, tool, product to do it!?
In all fairness, most of your "likes" play some roulette. Taking snapshots and
copying is fine and dandy, but cannot insure application data integrity. Some
might have agents for popular databases, but not necessarily everything (see
next paragraph).
Ideally "writers" have to be quiesced (suspend write actions in a good way)
somehow so that the data on disk prior to snapshot is integral. Now, with that
said, the roulette wheel is definitely slanted in your favor. Just noting that
the techniques that many things do aren't as fool proof as they might have you
believe.
(btw, I think I just hinted as to the common recipe that is used to pull this
off (with the stated flaws), at least part of it)
