What is the preferable partitioning scheme for RELIABLE snapshots of / as well as /home?
At present I have,
- sda1 —> 300mb — FAT32 — /boot/efi
- sda2 —> Balance (about 922.42GB) — BTRFS — Mounted on /, /home, /run/timeshift/backup, /var/cache, /var/log
- sda3 —> 8.8GB — Swap
At present, I have multiple timeshift snapshots. However, restore to any of them causes broken system.
Here is the output of command inxi --admin --verbosity=7 --filter --width
