I am working on setting up a home server but I want it to be reproducible if I need to make large changes, switch out hardware, or restore from a failure. What do you use to handle this?

I use snapshots, once a month an image is made of the entire drive, and I have Duplicati that backs up to cloud. Whatever choice you make tho, remember 3,2,1, and backups are useless unless tested on a regular basis. The test portion always gives me anxiety.

    I'd really like to know if there's any practical guide on testing backups without requiring like, a crapton of backup-testing-only drives or something to keep from overwriting your current data.

    Like I totally understand it in principle just not how it's done. Especially on humble "I just wanna back up my stuff not replicate enterprise infrastructure" setups.

    You can use qemu utilities to convert your Linux disk image to VDI which you can then import into VM Workstation or Virtualbox:

    qemu-img convert -f qcow2 -O vdi your-image.qcow2 your-image.vdi

    One thing you might run into is that Ubuntu server images often use VirtIO drivers, So you may have to make adjustments for that. Or you may run into the need for other drivers that VM Workstation or VirtualBox don't provide.

    ETA: There is also StarWind V2V Converter
