Eskating cyclist, gamer and enjoyer of anime. Probably an artist. Also I code sometimes, pretty much just to mod titanfall 2 tho.

Introverted, yet I enjoy discussion to a fault.

  • Recently helped someone get set up with backblaze B2 using Kopia, which turned out fairly affordable. It compresses and de-duplicates leading to very little storage use, and it encrypts so that Backblaze can’t read the data.

    Kopia connects to it directly. To restore, you just install Kopia again and enter the same connection credentials to access the backup repository.

    My personal solution is a second NAS off-site, which periodically wakes up and connects to mine via VPN, during that window Kopia is set to update my backups.

    Kopia figures out what parts of the filesystem has changed very quickly, and only those changes are transferred over during each update.







  • It combines capacity without any fancy striping. It can still provide some performance benefit as different blocks of the same file can be stored on different drives, but it doesn’t stripe data across the drives for performance.

    It also allows you to just add more drives later. The drives don’t need to be the same size or type. You can also remove drives, provided there is enough free space to move the data on a drive to the ones that will remain.

    It really just pools the storage capacity into one big volume.

    If a drive fails, it still takes the whole volume with it tho. But as long as you monitor smart, it is fairly simple to try ejecting it from the device group before it takes the whole thing with it.



  • If you just want to combine their capacities, and don’t need redundancy, just use single mode?

    No need to use a raid mode for multi-device btrfs.

    Edit: You could also do two volumes.

    Split each drive in half. Use the first half of each drive for a raid1c2 volume to get 1.5TB of redundant storage for important data.

    Use the second half of each drives for a raid0 volume to get 3TB of faster storage for games.
