fuck yeah monday checkmarks, bitches!
Recently read a comment here: “Think you have a backup? Delete your drives now. If you’re hesitant, you don’t really have a backup.”
As true as that is: I’d be in the “hesitant” category because I only back up my data / containers, not my bare metal system and its config. Do you guys? (Proxmox users will probably do, but what about the rest?)
I actually did that. Or well, I was planning to upgrade the Debian version and instead of doing it in place I replaced the drive (kept the old around for a while just in case) and did a clean install. I didn’t make any new backups or moved configs or anything outside what I already had, the system was back to operations faily quickly. The main reason, I have a markdown file describing every configuration and recovery step needed to get a fresh system to a fully working state in case of a disaster, and my test showed that it worked great. It does take a bit of effort to keep it up-to-date, but as shown, really worth it, and it douples as a small wiki for accumulated knowledge. I do wish to play with Ansible at some point if I have the time, but this works for now.
whenever the self hosting mood strikes, i try so much off the wall shit that it’d all be irrevocably broken if i wasn’t able to scrap the whole day and reload last nights back up!
i keep each group of services in their own lxc so at least only a part goes down if so!
Congrats on becoming one of the 5% of ppl who backup, but actually also test them.
5 %, that many?
There are two kinds of self-hosters: those who backup, and those who will start testing em after their first failed restore.
How do you check?
You reapply/ reload database and do all the recovery procedure on a clean new installation for everything. Disaster recovery is much a thing together with backup. Depends on your infra how to proceed in concrete steps.
rm -rf /(don’t actually do this obv)
Here, you dropped this.
–no-preserve-root
Its OK, root was preserved
Restore a backup and make sure everything is where you left it.
yep! restore a lxc on the backup machine and shut down the main one for a second
Thats good. So many places I see just accept that backup job completed without errors means backups are ok.
What are you using to run backups?
proxmox style
apologies if that is not a lot of info!
Proxmox VM snapshots and backups, plus proxsave I assume?
Huge! Feels good, huh?
