Syncing directories between unraid servers - best way? (aussie.zone)

G'day,

tl;dr - have two unraid servers in geographically independant locations, want to use them as duplicate / redundancy storage of some shares.

Unraid server at home, 120TB of storage but only need to sync ~10TB total which is spread over 3 shares.
Bare metal Ubuntu server at work, 12TB of storage, but only need to sync ~6TB total over the equivalent of a single share.
Have a second Unraid server with 26TB of storage I plan on taking to work. I want to backup my ~10TB from home to work, and my ~6TB from work to home.

Currently have Crashplan running on both ends which keeps up fine with the work data size, but will take literally years to upload home volume as it is so dang slow (~3Mbps, constantly stopping to rescan millions of files) so want something else in place ASAP. Will leave Crashplan running too. It'll catch up eventually.

Home has 400Mbps upload, work has 100Mbps upload so speed shouldn't be the issue.

Is Syncthing the answer? Was thinking of doing a read-only share on the sending end.

So I did some digging, and it's less clear than I thought.

I come from the embedded development world, where bare metal has been in use for a long time. Pre-2000s, this is exclusively what the term meant. Sometime around the mid 2000s, the virtualization services starting coopting the term.

So I guess it does indeed mean both, but being a stickler for tradition it doesn't sit right with me. The term just makes more sense when you're applying it to the hardware; bare. No middleman, and that includes an OS.
