Hi everyone,
I need to create a copy of a few datasets in another FreeNAS server and keep them synched... if they synch overnight that is sufficient.
The objective is (1) protection from accidental deletion (not using snapshots, see below), (2) protection against loss of pool, (3) doing all of that while doing the synch only on metadata when possible — i.e. when moving a 10 TB directory tree from /foo/mine to /bar/mine I would want only the inode (the zfs equivalent) to be updated as opposed to triggering a 10 TB copy. Same when renaming bob.tar to bobby.tar.
On a side note, I have been afraid to use snapshots because of item (3) above. Not sure what the impact would be on the disk usage. And it seems that replication is only available on snapshots.
All data changes (moves, renames) is done from windows machines.
Thoughts?
Thanks!
