Stumbling through getting a proper backup regime in place. I have an unraid system running a proper array, and am trying to setup backups for two separate machines (one windows one debian). I’ve successfully setup a file share, and have duplicati running. Are there disadvantages to just setting the network folder as the destination for the backup? It seems a little hamfisted (and the data rates are terrible).

It seems like there’s probably a better way to do this…

    I think you’re asking about the Samba share? If it works, there’s no real downside except the speed and general wonkiness of the SMB protocol.

    As I would rank the different options:

    1. Rsync+SSH would be fastest if you’re sending entire directories and not packaging first. A bit slower if sending huge files.
    2. NFS would be fastest if sending prepackaged large files, but overall slower if sending a bunch of smaller files
    3. SMB will be slowest in any scenario, but may be easier for you

      SMB isn’t really all that slow these days.

      I have NFS and SMB shares set up (same directory) and copying files to/from them maxes out my gigabit LAN.

      SSH on the other hand is slower, because there’s more CPU overhead.

        All data and benchmarks would disagree with you. If you find something showing that SMB isn’t slower than the others mentioned, I’d love to see it.

          I disagree with the other person, rsync + ssh is faster even in my own benchmarks. But samba is plenty fast enough these days, I can easily have it max out my gigabit network so I don’t need anything faster. So for me (and I would guess the majority of people) speed really isn’t a concern anymore, so I use samba because it’s easy to use and it makes sharing network folders to anything else a breeze.

          It’s like phones. Yeah technically the newest iPhone is faster than this years budget Samsung. But when’s the last time your phone was actually a bottleneck? (Unless you’re one of those people who play games, in which case, actually please respond cause I could use some really nice idle city builders for my phone pls)

      This is really helpful thank you! I think it’s samba share? Whatever Unraid has just baked in and calls “shares”.

      Googling rsync that looks like it’ll work, and faster is better!

      While I do want true backups of a few drives (as in: if a drive fails, restore the backup to a new drive, physically swap it out, and you’re good to go), the majority of the data I’m just looking to have it “backed up” (as in: all of the files are present in more than one location). The majority of the data is ~18TB of media for my plex server. My unraid is: 1x 2TB, 1x 10TB, 1x20TB and 1x20TB(parity). It sounds like Rsync-ing the 20TB drive with my plex media and the 20TB unraid disk would get me what I need?

      Thanks for the pointers, getting a few things to google is incredibly helpful.
