I use macOS just to get that out of the way. It just works for me. I’ve tried Linux and windows isn’t really an option.

I just want to get your opinions on a redundancy workflow to see if it would satisfy not up time but availability.

So I have a Mac server with a Z2 volume of about 26TB used.

This syncs to my GSuite storage. This then syncs down to my extra soon to be JBOD volume (none of the drives are the same capacity). Would JBOD be permissible for general fault tolerance since I have a Z2 volume backed up to the cloud and then mirrored to the JBOD.

So I have 1 offsite, 1 fault tolerant (up to 2 disks out of 8) and 1 JBOD volume (according to macOS the JBOD volume can have the last disk removed and replaced, currently checking if the disk itself can be cloned in the event of smart failure). I also have separate versioned external drives for the most important stuff for ease of portability and offsite. Also the drive cages that have the ZFS and JBOD volumes have handles for grab and go as well.

Is having a JBOD volume that can loose all data permissible if I have an offsite and a local fault tolerant volume (2 separate Mac servers)?

I’m aware of other options but there are issues in relation to Big Sur that prevent or make some of the options not viable/complex.
