I wanted to test it as a backup solution. Maybe that's crazy in

Basically, once a week detach the 'backup' pool from the mirror,
replace the drives, add the new raidz to the mirror and let it
resilver and sit for a week.
Since you're already "spending" the disk drives for this that get
detached, it seems safer to me to just 'zfs send' to a minimal backup
system, and remove the extra drives from your primary server. Less
overhead and the scrub can validate your backup copy at whatever
frequency you choose.
You don't even need the same pool layout on the backup machine.
Primary can be a stripe of mirrors, while your backup can be a wide
raidz2 setup.
