hmm... i'm having Thoughts on how to handle self-hosting stuff locally for friends & taking good backups...

• toss good NVMe drives and ECC (unbuffered) memory into an Optiplex Micro box. 10th gen or newer probably, both for recency and just Stronker than older gens

• build a small but capable box to run Proxmox Backup Server on (not sure if I'd go with RAID 1, RAID 5/6, or RAID 10 but later me problem)

• take regular (daily or twice-daily) encrypted backups from micro box to PBS box via container-level suspend-mode backups

• store last few backups locally on the box itself (if that's like. possible with PBS integration)

• store more backups on the PBS box. copy those same backups to Backblaze B2 & keep them in constant sync (whatever PBS has, B2 also has). though try to avoid that going the other direction (PBS can only remove its own backups, and B2 removes its own backups as well, neither should influence the other)

It might just be enough? The PBS box would be pretty basic, just a few core Ryzen chip with enough storage space & network speed to accommodate the throughput of backups coming in (which should be MORE than enough unless I can get like, an M.2 E-key to 10Gbps plug shoved into a box). The Optiplex box would be handling most of the heavy lifting, so i might bias towards an i7-based unit for some extra compute power when it comes to taking, compressing, and encrypting the suspend-mode backups before making them the PBS server's problem. who then gets to deal with shoving it to Backblaze as well.

the PBS server would really just be doing that and sitting idle most of the time, just making sure it keeps the girlies together. I don't think? it'd really need all that much power in the grand scheme of things. the fleet of Optiplex boxes could all run their own set of tasks, I could get a 12th-gen box for my personal stuff (Jellyfin included) and re-purpose my current 10th-gen box as the host device (swapping out the WiFi E-key for a faster wired network plug) and put in more robust storage (and swap the memory for at least decent ECC stuff, so long that the Optiplex Micro's support it).

The PBS server should? at least support un-buffered ECC DDR4. From what I'm seeing, Asrock and Gigabyte B550 boards typically do across the price range, so that should be OK there. Toss an Intel X550 network card for 10GbE local backup network to guarantee only the read/write process is the bottleneck. I'd probably have the Optiplex box built-in 1GbE port be the actual service network? At least keeps the two separate so you can't physically interfere with the backup comms? IDFK here lol this is theoretical.

Anyways I think that might be the best? way to go about things. I could build in a Jonsbo N4 and get even more hard drives, but IDK more hard drives = more cost and more (idle) power draw, and since shit is backed up in like, twelve spots anyways it should be OK to have a smaller box whose whole job is backups?

shrug
