There does not seem to be a topic here or [specific to this] in the User Guide/help systems. The closest I found was here:
(In case this should be moved there).
It took me a bit of poking around to finally determine that neither product (WDMBL/WDMC) can back up directly to another similar WD device (in a mirroring/syncing/incremental backup capacity). I would have LOVED to just purchase a second MBL or WDMC and point the old one at the new one and say “go” and continually sync each other. Not only is this not an option (like it is with BuffaloNAS products, for instance), but you cannot even push automatic SafePoint backups to another WD device beyond the local network. So. this kind of kills the 321 backup rule (becasue I cannot maintain a WD device off-site without a manual sneakernet solution, or some SSH tunnel trickery).
Anyway, assuming that is all correct, I’m just checking on compatibility of Safepoint backups from/to/between WDBML and WDMC devices. A big reason I purchased a WDMC instead of going back to BuffaloNAS (which again, has a much easier fire-and-forget sync option between location-independent devices), was so that I’d not have to set up everything from scratch while tranisioning [upgrading] from my existing WDMBL to a new WDMC device.
So, I’ve just started creating a SafePoint to an external WD Ultra Passport drive in hopes that the WDMBL safepoint will seamlessly apply to my new WDMC device…
Nowhere does help or forum indicate that this will work (User Guide for MBL only states it works from MBL to MBL). But I’m really hoping this works and I don’t have to copy everything manually…
I haven’t seen any posts blowing up saying it doesn’t work, but that doesn’t seem to be endorsing that it does.
Similarly… since I’m going to keep my old MBL as a backup… I wonder, will a WDMC SafePoint be able to be applied to an older WDMBL device? (say, in the case my WDMC dies and I want to quickly be able to get back up and running on the older hardware).
Thanks for reading and sharing any pointers.
