Hello. I need your thoughts on what to do for backup on a pure Linux laptop (no Windows or dual boot).
My setup
- a 2.5" SSD
- a mSATA SSD
- this laptop can get connected to a docking station with its own hard drive (caddy via optical drive). This can be HDD or SSD.
I carry the laptop around 60% of the time, the dock is only when I need to use the monitors. I.e. the 2.5 inch SSD and mSATA SSD are often on the move, the dock's drive stays at 1 place.
What I need
I need to backup my personal files in /home. I do have cloud storage but I want to keep an offline backup of things.
I want to somehow backup my system settings. So the: /home/user/.config and other important libraries and settings in /. So in case of a kernel bug and I need to reinstall (very rare but just in case), I can just restore the settings quickly.
My approaches
Keep the OS on one drive, preferably 2.5" SSD for speed. The mSATA is for system files backup, via Timeshift. The dock HDD is for heavy media like movies => I use Dejadup for this. So I can set it up to backup whenever the dock is connected.
Split up the drive: mSATA for root and everything else is in the 2.5" SSD. All backups (Timeshift and Dejafup) will be via the dock's HDD.
Appreciate any inputs. I have no preferences for filesystem (currently everything is EXT4), but would like to know what is best too.
