What's the difference between Ext4 + SnapRAID and btrfs?

  • Right now my setup is a Raid1 with Ext4, and I was thinking about converting it to a btrfs pool. However, it looks like the SnapRAID plugin can provide all of the file integrity needs I have, without the implicit risk of changing filesystems. Is this correct?

  • IIRC you are the one running now with mdraid RAID-1 with ext4 on top thinking about a replacement?


    If I understood the SnapRAID concept correctly you won't have luck with just 2 disks (but I might be wrong) and you need to copy your data around anyway since SnapRAID on top of mdraid is most probably nothing that makes any sense.

    Yeah, that's me. Also, I got my setup (mostly) upgraded, so thank you.


    Thanks for letting me know. I noticed I had it installed when I upgraded, but I couldn't tell whether it was doing anything and if it was, if I needed to replace it.
