I know there are a bunch of questions on here regarding disk space and Timeshift, but I feel as though disk space issues can be pretty individualized, so - as a total novice - I wanted to check in before I break anything.
I am running Linux Mint 18.3 dual booted onto a Lenovo Thinkpad Yoga 260 - 8 GiB of RAM. I really only use this computer for programming and regular internet stuff - I don't make a ton of system configuration changes at this point (not since I first set it up in March and a few periodic changes and updates since then). I have Timeshift running backups, and until recently, my Schedule was set to keep 5 daily backups and 5 boot backups. This is clearly far too much since I rarely make system changes, so I changed the settings to just keep 1 daily and 1 boot.
Also, when I initially set up this system, I wanted to install Spotify, and I did so via snap, which was pretty unnecessary.
Timeshift seems to be wreaking havoc on my disk space, and snap is saving things to /dev/loop devices. Really unclear what that is all about. (See attached screenshots.)
A few questions:
1 - Is it safe to delete old Timeshift backups? Since these are incremental backups, I imagine that deleting an older backup but keeping a new one would leave me missing things. I clearly have too many, and the only sizeable ones are the one from today (10/20) and the one from 3/5. It would be great if I could free up some space there, but I'm not sure what's safe. Can I just make a backup today and save it to a USB stick and delete at least the old backups?
2 - Since I installed snap just to install Spotify, can I uninstall Spotify and snap (
sudo apt autoremove --purge snapd
)? Or is it critical for my setup at this point...not sure what the deal is with snap core, to be honest.Thanks so much for your patience with my beginner questions, and I appreciate any advice in advance!
