Configure mercury volume offsite sync

[geerlingguy]

Probably via ZFS sync, now that I have 500+ Gbps upload from the office. My idea is I can have that directory synchronize between my home and office, maybe with a Pi and a 2 or 4 TB NVMe SSD at home (maybe two in RAID 1?).

Ideally I could edit off either home or office and work that way, but if not, one-way sync to backup at home via ZFS replication would be nice.

I've never had this before for my 'scratch' disk but it would be nice insurance to have, since I have two local backups, but nothing offsite, for works in progress (I do have a manual backup disk I carry with me, but if I have to run out of the building in a fire... I ain't running back in to grab it!).

Another option would be to use a standard S3 bucket (instead of Deep Archive) and sync that way using the same rclone setup from #14, but that would be a little messy since so many files change all the time.
