September 7, 20232 yr My plan is to use SATA SSDs for my main storage pool (ZFS/RAIDz1), and run a regular auto-backup job (clone, not incremental) to a large enough hotswap HDD used as a standalone unassigned drive, i.e. I don't want to use an attached USB hard drive for my on-site backup. I want to format the destination drive as ext4, so in case there's a hardware failure with the server/NAS, I would still be able to access my data on a Mac using the Paragon Linux FS drivers. (Afaik OpenZFS isn't stable enough on macOS.) The HDD would be in a hotswap bay, so I could use alternating HDDs, with one always stored safely off-site. Is this possible?
September 7, 20232 yr Community Expert UD plugin can mount ext4 drives, not sure it can format the, but worst case you can format elsewhere if needed.
September 7, 20232 yr Author Thank you. That would answer part of the question. With Paragon's extFS for Mac, I'd be able to erase/format the drive before adding it to the server. The other part of the question is, how the backup task would work with alternating drives. Those drives would have different IDs, I assume, so does that mean that I would need to create two backup tasks? Meaning that Unraid will run only ever one of the two tasks depending on which HDD is currently mounted via the UD plugin?
September 7, 20232 yr Community Expert Solution You can create a script for each UD drive, as soon as you plug it in it will run the backup, see the UD plugin support thread for more info.
