I experienced Timeshift with LMDE about 2 or 3 years ago. (Linux Mint Debian Edition) when I heard about it I immediately re-installed using BTRFS to try it out. I gotta say snapshot backups are very fast. It really surprised me. I tried out some config changes and restores and it went very smoothly. If you can leverage Timeshift in grub then I need to watch the video and set that up asap. Nothing more annoying than trying to diagnose a failed boot or giving up and reverting to a previous kernel. (Spoiler: It’s always nvidia kernel modules)

Space is vast. Just like dat ass.

Ethernet speeds historically were measured in 10/100. In my past life I worked for an a small rural isp. And part of my learning I was taught that cat5 was 8 strands of wire, or 4 twisted pairs. I got very familiar with crimping patch cables. If one strand were cut a network card would negotiate down to its lowest speed and still work at 10mbps. Operating on 4 wire or two pairs. It’s possible with those numbers you had a bad connection, or a broken strand in the cable and it auto negotiated down to 10mbps. To this day I still crimp my own cables, and I own a cheap cable tester to make sure the crimps and cables are good.

I’ve had very bad luck with raspberry Pi’s and SDCards. They just don’t seem to last very long. I swapped to usb storage and things got somewhat better. I just had a usb drive die after 3 to 4 years of use. When I was still using SD it seemed like multiple times a year. Heat. Power loss, you can only punch holes in silicon so many times before it wears out. Whatever the reason.

My approach for this is configuration backup not the entire os. I think this approach is better for when it’s time to upgrade the os or migrate to a new system.

For my basic Pi running WireGuard and DNS, I keep an archive of documentation on steps to reconfigure the system after a total loss. Static configs are backed up once, and If there are critical configuration items that change then I back those up weekly. I’ve got two systems (media related servers, not Pi’s) that I keep ansible playbooks to configure 90% of the system from scratch so it’s as hands off as it can be.

Assuming the boot partition is still there and mounted. Just empty. If it were me I would try to reinstall grub2 and kernel packages. I don’t know what errors I would encounter trying it, so that would be the next hurdle.

Old I.T. Proverb: Documentation is like sex. Even bad documentation is better than no documentation at all.

As long as we’re taking the “high road” and kicking someone in the gut for the way they look could someone link to who this is and what they said?

Some of those apps are available through the community package center. If not then you can run a docker environment or a virtual machine on the DS and run whatever you want. It’s got a lot more horsepower than a single board computer, but I still recommend separation of duties and let the NAS be a NAS. Put your services on a server or separate virtual environment.

Influxdb is a “time series” database for storing metrics. Temperatures, ram usage, cpu usage with time stamps. Telegraf is the client side agent that sends those metrics to the database in json format. Prometheus does pretty much the same thing but is a bit too bloated for my liking, so I went back to Influx.

Grafana, influxdb, telegraf agents. Easy to setup. Barely any configuration required. Everything you asked for in the default telegraf agent config. There are dashboards with plenty of examples on grafanas website.

I know of a better one. https://youtu.be/jcAbYczBgsU
