Two separate Raid 1 on OMV 6 with 4 slots HAT on RPI4

good morning

I managed to pair an 8GB RPI4 with a Radxa SATA HAT 4 slot. 
The first two slots are occupied by two mirrored disks (Raid 1) and do daily rsync without problems (OMV 6)
The other two slots are empty for the moment.
My idea, to use them, would be to add two more disks in raid 1, and use rsnapshot to create and manage monthly / yearly snapshots. 
In this way, I should have a reliable backup. 

Is it possible to create another additional raid 1 and backup with rsnapshot on these? 
what do you think? anything I should keep into consideration?

thanks for support
Vincenzo

It is a waste of disk space to have long term backups on a raid. Use the two as seperate disks an do the backups alternating between the disks.

That sata hat is usb as well. raid over usb is not supported by OMV.

Hi both

thanks for the info.

ryecoaaron : I know that OMV does not support USB devices. But up to now.. it is working.. in home environment..without issues.

Zoki: good suggestion.. I did not think the possibility to use those disks separately, and alternating the backup. I will make a try..

I hope that putting these 2 disks, will not make noise to existent raid 1 setup..

thanks

Just warning you. I have that hat as well. It is a paperweight now. rsync/rsnapshot to sync two or more disks is much more reliable.
