Backups on dev.endevour

Practice your restore strategy

Thu, 21 Dec 2023 00:00:00 +0000

My homelab set up is a production node, (pve-prod1) a backup production node (pve-prod2) and a development machine (pve-dev1). They are all G2 800 minis, but pve-prod1 has a i7 6700T and 32GB RAM, where as the other two are i5 6500T with 16GB. My thinking is that the older two can easily share the workload of the main production machine for disaster recovery. Everything is virtualised on top of Proxmox, so sharing up the VM’s and containers is trivial.

Docker volume backup is more complicated than it should be

When I set up my first Docker container (I think for Uptime Kuma ), I had read around and understood there were two choices for persistent; bind mounts (where the data inside the container is effectively a symlink to a location on the local file system) or name volumes where Docker abstracted that away a bit, so you didn’t have to worry where it was - I sort of understood Docker ‘managed’ it.

Proxmox LXC backup to NFS share failing

I was doing updates on all my nodes and VM’s today, and backing up the VMs that aren’t already on a backup schedule. On my dev machine I have a Debian LXC container that I mostly just use for trying out Linux commands and playing around. I used to have a backup of it that I used a lot - after playing around I like to set it back to a fresh install plus my ssh keys - but I lost it somehow when moving the VM to new metal.

Using NAS for Proxmox backups

Mon, 10 Apr 2023 00:00:00 +0000

A few weeks ago , I was very excited to be able to take a snapshot of a virtual machine, copy it across the network from that Proxmox node, copy it back across the network to a different Proxmox node, start it there, and have it up and running, without it noticing it was actually on different hardware.

Backing up a VM is pretty simple, you just click on the node, choose Backup and click the Backup Now button. The ease, and completeness of backing up a VM is one of the main reasons I’m using Proxmox for my systems.

Proxmox Backup Files

I’ve got some extra RAM to drop into the HP 800 G2 mini that I use as my production server. I feel like that’s a low risk change, but since it’s easy to take VM snapshots I shutdown the VM’s and did that, and wanted to just copy them off the local storage.

I’m moving towards having these backups (and the ISOs) on the NAS rather than locally, but have not implemented that. So to get my backups I need to SSH in and find them.

Moving a VM between two Proxmox hosts

Thu, 16 Feb 2023 00:00:00 +0000

So, the very small datacentre has undergone a major hardware upgrade today. The HP 800 G1 is joined by an HP 800 G2. Four core i7 vs the old two core i5. Double the RAM to 16GB, four times the disk. The old machine will become a dev/play machine - still virtualised, and the new machine will run the production apps, mostly in Docker containers.

Since everything is containerised, I did consider running Unbuntu Server on the bare metal of the new machine, but running it on Proxmox will give me some flexibility, and since we’ve stepped up the underlying hardware resource so substantially, performance will be well in front anyway. Plus it will give me some flexibility if needed in the future.
