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.
I use SyncThing and it works great for my use case but I think it is not the recommended option for backups.
If you are running zfs on both servers you could look at sanoid.
