Not exactly self hosting but maintaining/backing it up is hard for me. So many “what if”s are coming to my mind. Like what if DB gets corrupted? What if the device breaks? If on cloud provider, what if they decide to remove the server?

I need a local server and a remote one that are synced to confidentially self-host things and setting this up is a hassle I don’t want to take.

So my question is how safe is your setup? Are you still enthusiastic with it?

    Absurdly safe.

    Proxmox cluster, HA active. Ceph for live data. Truenas for long term/slow data.

    About 600 pounds of batteries at the bottom of the rack to weather short power outages (up to 5 hours). 2 dedicated breakers on different phases of power.

    Dual/stacked switches with lacp’d connections that must be on both switches (one switch dies? Who cares). Dual firewalls with Carp ACTIVE/ACTIVE connection…

    Basically everything is as redundant as it can be aside from one power source into the house… and one internet connection into the house. My “single point of failures” are all outside of my hands… and are all mitigated/risk assessed down.

    I do not use cloud anything… to put even 1/10th of my shit onto the cloud it’s thousands a month.

      It’s quite robust, but it looks like everything will be destroyed when your server room burns down :)

        Fire extinguisher is in the garage… literal feet from the server. But that specific problem is actually being addressed soon. My dad is setting up his cluster and I fronted him about 1/2 the capacity I have. I intend to sync longterm/slow storage to his box (the truenas box is the proxmox backup server target, so also collects the backups and puts a copy offsite).

        Slow process… Working on it :) Still have to maintain my normal job after all.

        Edit: another possible mitigation I’ve seriously thought about for “fire” are things like these…

        Or those types of modules that some 3d printer people use to automatically handle fires…

          Yeah I really like the “parent backup” strategy from @hperrin@lemmy.world :) This way it costs much less.

            The real fun is going to be when he’s finally up and running… I have ~250TB of data on the Truenas box. Initial sync is going to take a hot week… or 2…

            Edit: 23 days at his max download speed :(

            Fine… a hot month and a half.

              I’m doing something similar (with a lot less data), and I’m intending on syncing locally the first time to avoid this exact scenario.

      Absurdly safe.

      […] Ceph

      For me these two things are exclusive of each other. I had nothing but trouble with Ceph.

        Ceph has been FANTASTIC for me. I’ve done the dumbest shit to try and break it and have had great success recovering every time.

        The key in my experience is OODLES of bandwidth. It LOVES fat pipes. In my case 2x 40Gbps link on all 5 servers.
