I just setup a Rpi 4, 4gb and two External, self powered USB3 WD 4GB drives. My goal was to do Raid 0 as I don't really need performance or mirroring. Its simply for weekly backups, large files. No media streaming, etc. Gigabit network connected. I found in the setup you cannot do raid 0 on the Pi hardware without add-ins.
I am hoping to create one large volume (4g x 2 + ~8gb) or disk to be used for both Timemachine and Acronis image backups. Acronis backups will have a folder and Time machine another folder.
What is the best format for this use case and how can I join both disk to appear as one volume. After that, can I tell Timemachine to only use a folder on that volume and limit its size.. (I know, more of a mac question).
Thank you in advance. I will be reading the various other posts but its getting confusing quickly
Maybe I did not need to use Rpi4 for this application of OMV?
