remote cloak
I'm quite new to arch, so far my system has worked just fine.
But, I have become increasingly worried about how to secure my system if it ever breaks.
I heard timeshift is a good option.
Additionally I manually backup my personal files to a seperate HDD. I wonder if there is a way to automate this process or make it easier, maybe actively mirroring any changes live using syncthing?
I'd appreciate any input for what is reasonable to worry about.
Also is it feasable to preconfigure your archinstall based on an existing system configuration? So that I don't have to reconfigure everything if I were to reinstall my os?

For offsite backup, you can set up a restic (or rustic) service and a systemd timer to do this automatically.
[Unit]

# only run if the backup drive is online and mounted
ConditionPathExists=/dev/disk/by-uuid/xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx

timeshift was meant for system restore. use dejadup for backups

to be clearer: timeshift et al are for snapshots, which store previous copies of your system on the same drive
this is useful for undoing changes, but if the drive dies it all goes poof, so it’s not a real backup
as for backing up your files to an HDD, restic is a good suggestion
heavy tartan
so does dejadup
mossy forge
dejadup just uses restic behind the scenes, doesn’t it?
so sure, use that if you’re not familiar with using the CLI
as for automating it, unfortunately there’s a trap here
if you want to fully automate it the drive has to always be plugged in, which makes it more vulnerable to the various antics you might do on your computer
but if you keep it detached most of the time, you will have to remember to plug it in for backups, which makes it not automatic anymore

no, YOU specify the harddrive in timeshift, in my case external drive for backups and snapshots
also, you canadd personal folder in timeshift settings aswell as autosnap
mossy forge
oh, I didn’t know that actually!
in that case timeshift would be a good backup method as well, but you still have to be mindful about when your drive is connected
