I'm currently in the process of setting up a NAS system mainly for backing up my computer and probably also for streaming media files to my devices.
For these purposes, I decided to use OpenMediaVault with two new 4GB drives as it seems that it's a stable running software and that it has all the needed features already built in.
But it's not very clear yet which filesystem to choose. I'm currently tending to go with BTRFS instead of ext4 as I really want to have the "self-healing" as well as simple snapshots.
Apart from that, I would like to set up my drives in RAID 1 so I can benefit from a higher data availability.
Now when it comes to BTRFS, there are two options on how to set up my RAID 1.
Either one is using the standard Linux software raid with mdadm and the other one would be "native" btrfs raid.
What are the advantages/disadvantages of each?
