Ignorance and hubris are consequences of youth. The fact is that your parents do probably know quite a few things that you don’t, if for no other reason than they have more lived experience. That shouldn’t necessarily make you feel foolish. Part of growing older is realizing that you possess a microscopic fraction of all the knowledge in the universe. Meaning that most people know things that you don’t and you could learn something from them. That’s wisdom. Some adults never embrace that, seeing their ignorance as an asset and turning their hubris into blind arrogance. Those people should feel foolish because they are fools. But they probably don’t.
I don’t agree with every decision my parents made. But in my mid thirties, I do now understand why they are the people they are and why they made some of the decisions they made. They were far from perfect parents. But they did ok, especially in light of the incredibly shitty examples they both had for parents.
My advice is avoid tape backups. The cost, risk of media degredation, and management overhead make them not worth it, especially for a homelab.
Also, restoring an entire VM is almost easier than recovering a single file, just because of the sequential nature of reading data from a tape. Data recoveries are pretty slow in general.
I backup to an external hard drive with regular copies to iDrive S3. Been doing it that way for a number of years with no problems.
