So I’m wondering if an upgrade is safe because
Imho that’s the wrong question. Without backup nothing is safe whether you pate the OS or not. Anything can happen (the disk can die, the computer can be stolen,…) and, yes, most upgrades should go without any issue but then one won’t go well and then what? You need to do backups, we should all ;)
I’m currently using Proton and still have to move to another service
I’ve moved to Filen (German end-to-end encrypted cloud you can rent (or buy) for a year or… a month (maybe worth the cost at least for a month when you will upgrade) and it works real nice for me on Mint 22.1
Depending the storage you need, you can get from 10 to 50Go for free: 10 base *+10 if you use crate your account using this affiliate link (no string attached, it’s real free storage) and up to 30Go more if you also share your own affiliate link. If you’re wondering, I use their 2To lifetime plan.
2/ Related to the first question: I’m using a old laptop (asus zenbook from 2015 or 2016, can’t remember), so would I be find with an old hardware such as mine?
It’s not that old, you should not worry much ;)
Hi & welcome from a fellow Mint user.
It’s a stable distribution that comes with a lot of things preinstalled (so less extra stuff to install, but also a lot of stuff you might not need)
I would add to that:
On that topic,I’m not much of a geek (a 50-something dude and a 35+ years Apple customer) but I did learn to use git to keep a backup of my config folder. So, when I screw up something (so far, Mint has not once screwed up anything by itself, the few issues I had to deal with were all me-related) , I know I can revert back to the previous version of whatever settings I’ve just damaged without difficulty. Learning the basic of Git is not hard, it’s just…odd, and it works great. If it was compatible with LibreOffice files I would love to use if for that too…
