I'm still trying to get a good backup strategy. I am currently using Duplicati but I cannot get the before script execution to work. I will eventually look at Kopia.
What kind of hardware are you using for a mini lab? I want to switch from a raspberry pi 5 to a small form factor Intel based system so I can run Proxmox. I was looking at the Lenovo m920q or an Optiplex 79xx series machine.
Do you have any recommendations for backups or the hardware switch I mentioned?
I use cron schedules to run scripts that backup my important stuff to s dedicated backup drive, then copies the backups to a different external drive, then upload the backups to a dedicated backup cloud storage account. Then it deletes any backups older than a month.
Have a look at Backrest for Restic. It works great with pre/post scripting and supports healthchecks for monitoring status and stats.
Also is a nice easy to use WebUI which is great for servers.
I'll look at this again. I had it before and did not stick with it though I don't remeber why now.
I don't know Duplicati or Kopia, im mostly just using VM snapshots as backups. I store them in an NFS Share on my NAS.
I just posted my Minilab, check my history - I'm also using tiny Lenovos. m920q should be able to do anything you want it!
If you do make a switch to Proxmox, then Proxmox Backup Server is where it’s at for backups. Its de-duplication feature is incredible. I backup all my Proxmox VMs/LXCs with it, as well as my non-Proxmox hosts (laptop, etc.), with
proxmox-backup-client.Personally, I’m using a few of those tiny Beelink PCs (a couple Mini S12 and an EQ12) with the N100 processor, as well as a couple larger rackmount PCs I built for situations where I needed to add an HBA or some other PCI-Ex device. I do recommend something like a Beelink before building, though - they run Proxmox fine, they’re inexpensive, efficient, quiet, and each one can run a handful of VMs.
Yeah, I heard about Proxmox backup and that sounds really nice. Love the idea of being able to take a snapshot before any major changes to a VM and then if it goes south restore from snapshot very quickly.
