Backing up zvols?

Added by Dan Swartzendruber about 1 year ago

So I have my esxi datastore on a zvol on the nexenta box. Being CE, I only have auto-tier, not auto-sync, which is what I really want (e.g. I want to have the zvol backed up at a block level to an esata drive). Being stuck with auto-tier, is there even any way to do this (using auto-tier), or do I need to somehow roll my own?

well, enterprise will let you, but not community.

rolling your own would involve writing a script to zfs send the blocks.

hey are you doing a poc?

leading to an enterprise deployment

so you can pretty easily write a script which does this.. I asked because this would be "voiding" the warranty of enterprise setups

You can easily make a script that does a zfs send localsnap | ssh remotehost zfs recv /path/tosnap

Then the incremental looks like..

zfs send –i localsnap1 localsnap2 | ssh remote host zfs recv /path/tosnap

You could put it in a cron and have it run on a regular basis..

Hi Linda,

Do we need to get 2 enterprise license if we intend to use auto-sync. Or can we just purchase 1, i.e. the commercial edition auto-syncs to the community edition.

Two. Community Edition cannot be the target of an Auto-Sync, it is not supported. Both sides need to be Enterprise Edition if you wish to use Auto-Sync plugin to replicate data.
