Hello !
I am currently looking for a way to build a NAS with OVM on a rapsberry pi 4.
The NAS would have 2 disks (one disk for storage, the other one as backup of the first one)
It looks pretty simple to do, but I just want to know if there is any way to do automatic backups of the first disk on the second one.
If any of you have some advices for me, it would be a pleasure ! 
RAID0 is stripped.
You surely mean RAID1 which is mirrored.
But RAID via USB is not permitted on OMV.
What you can do is run a rsync job from one disk to the other.
There's some instructions on the forum guide section.

yes I meant RAID1, sorry !
Okay I will take a look at rsync
It will be more than enough.
Many on the forum use Pis as their NAS (me inclusive)
Of course, just don't expect it to be a power house.
For file serving and running some containers, it won't break a sweat.
See my signature to see what I use them for.
You might want to have a look at rsnapshot. If gives you a versioned backup. That way you can restore older versions of a file.
There is plugin for rsnapshot.

To be fair, if you leave the delete trigger off on the rsync job.. it does the same thing.
file, file(1), file(2), etc. If you need to restore a previous version, just use the command line to copy the "old" version back to the source.
Then once a month, or however often you need, just log in, enable the delete trigger, run the job manually, and the old versions are gone.
And more generally, do you think it is relevant to use the rp4 to build a NAS ?
I'll go against the grain here... I know a lot of folks use Pi's, etc. for a NAS.. but I'm not a fan. I think SBC's have their place (I use one for a backup server) but for every day home use, I prefer 64bit.

I don't think it is working that way. Disabling "delete" just prevents deleting a file on the target which is not on the source. But in any case an updated file on the source will overwrite the target and previous version is lost.

Weird... I know for a fact in previous versions this happened as I frequently would get just what I said.. file.txt(1), 2, etc.. when I had multiple copies of a file.
Interesting. This might make me have to rethink some things.
Thanks for pointing this out.
Can the RP4 supply the two 2TO SSD which will be plugged in USB3.0 ports ?
Or do I need to supply them separately ?
You should get yourself a self powered box to hold the 2 drives.

Do you have any model to recommand ?

Again, check my signature to see what I use.
Icybox is a good brand and the boxes use asmedia chipsets which are very rock solid.

Tell me if i am wrong, but new rapsberry pi 4 are 64bits, aren't they ?

64bit ARM...
I'm refering to amd64 architecture (probably should have been more clear on that). There's a big difference. One won't run on the other. For instance, I believe most of the new podman plugins votdev has been putting out in OMV 6, are only available for amd64, so they will run on a 64bit PC, but not on a 64bit ARM device like a Pi.
This can sometimes be an issue when looking for containers you want to use. Some may be only available for amd64. Granted, usually if you keep looking you'll eventually find the container has been ported to arm64 or whatever.. it's just kind of a pain (one reason I like Linuxserver containers, all of their containers have multiple images.. so they are pretty ubiquitous across all platforms)
Oh nice really cool ! I did not know about all these cards
But can I install OVM and Dockerwith some containers on it , regarless of the card ? Because I will probably install some apps like Plex, Radarr, Sonarr etc.. So do these kinds of apps are like "generic" and can run on pretty much all cards, or do they need to be developped specifically for a card ?
I will take a look at all these models, looking for one with 2 SATA (for 2 data disks), and one SATA (or nvme) for system disk

It goes by architecture, not brand or type. You can check the architecture on hub.docker.com. Images might or might not be available for
arm
arm64
amd64 (x86-64)
x86
