I just got my home server up and running and was wondering what you guys recommend for backups. I figure it will probably be worth having backups on cloud servers tjay are external, are there any good services yall use for that?

      Ehhh I would say then you have probabilistic backups. There’s some percent chance they’re okay, and some percent chance they’re useless. (And maybe some percent chance they’re in between those extremes.) With the odds probably not in your favor. 😄

      Not so much about testing, but one time I really needed to get to my backups I lost password to the repository (I’m using restic). Luckily a copy of it was stored in bitwarden, but until I remembered it, were perhaps one of the worst moments.

      Needless to say, please test backups and store secrets in more then one place.

    I use Restic + Resticprofile to back up everything and store it on my local HDD.

    Then, I use Rclone to sync the local repository to Backblaze B2.

    Here’s my general setup:

    Resticprofile doesn’t let me run other shell commands on a schedule, and because I wanted everything in a single configuration, I just created two new profiles which call the backup command. I then made the shell commands run before Restic, and then finally killed the instance before it got to actually run, which effectively does what I needed.

    Borgbase with Borgmatic (Borg) as the Software. As far as I know the whole Borgbase Service is from a Homelab guy (with our needs in mind).

    Also 3-2-1 rule!

    I use Duplicati connected to Storj with data volumes that incrementally get backed up once per month. My files don’t change very often, so monthly is a good balance. Not counting my Jellyfin library, those backups are around 1 TB. With the Jellyfin library, almost 15 TB.

    Earlier this year, I recovered from a 100% data loss scenario, as I didn’t (and still don’t) have space for physical backups. I have a 25 TB allowance, so my actual cost was €0. If I had to pay, it would have been under €1.

        Definitely 25 TB. I’ve used the service for a long time, since before they accepted credit cards. I attached my credit card one day and got a bump to 25 TB. Since that happened, I pay basically nothing and my account is still 100% storj token funded.

        Edit: I dug up screenshots I sent someone recently

          my account is still 100% storj token funded

          That seems to be the key bit, since everyone can use up to 25TB (if they can pay for it). Are you also hosting a node to earn credits tokens?

      I hate to ask the scary question, but have you tried to restore your backups before? I used Duplicati and discovered that none of my backups were usable and ended up switching to Duplicacy.
