How to make a clone to a second NAS
Hi All, I have a 316 NAS with some share and many snapshot, I need to clone all the share with snapshot contend to a second 316 NAS because the first has problem on btrfs (crash during balance). ...
The key here is your requirement to migrate the snapshots to the clone. That requires ReadyDR. But a ReadyDR backup destination is not a normal share, so you don't end up with a clone - you end up with a ReadyDR backup.
You can try using ReadyDR on a share on the old NAS, and then restore the ReadyDR backup to a local share on the new machine. You'll want to do that in stages (ReadyDR backup, restore to local share, delete ReadyDR), unless you have a lot of free space on the volume (keeping all the ReadyDR backups and the local shares simultaneously would require 2x the space).
Another approach might create ReadyDR backups for everything on the new NAS, then factory reset the old one, and restore the backups to the original. That has more downtime of course.
If you can relax your requirement on preserving snapshots, then rsync is more direct than using ReadyDR.
Hi StephenB,
your solution is good if starting from zero with 2 nas.
But I've the first nas with data + snapshot and I'm finding a solution to move all to the second.
I'll study various settings with rsync and readydr.
If was possible to move all snapshot in the readydr share under a normal share, this will be the solution.
Thanks, Giuseppe
