Which folders and files do I need to exclude from TimeShift?

Also is there a way to also exclude programs installed as .deb ?

I doing this to reduce Backup size as I have limited storage.

100GB - Windows 11
400GB - Storage
400GB - Mint
100GB - TimeShift

    I put /var/lib/flatpak in a separate btrfs subvolume. Timeshift only takes a snapshot of the root and home subvolumes.

      Oh. BTRFS is alien to me man. But a lot of people recommending it to counter the storage constraints. I have to learn it first.

    You can make this work using ext and Timeshift rsync. I have also opted to exclude /var/lib/flatpak/ because it’s quite large. With that, my 5 snapshots currently take up about 34 GB.

    However, I would recommend backing up your deb applications/packages (typically installed under/usr), as those can be critical for your system.

    When I did dual boot (good riddance) I gave Linux <100 GB and rest to Windows. I had additional storage partitions but in long term they made management harder for me so I mounted Windows partition for additional space. Here are my recommendations:

    • Merge “Mint” and “Timeshift” partitions.
    • Use BTRFS if you can. In rsync mode of timeshift, the disk will hold 2 copies of your current system + changes between snapshots. In BTRFS there will be 1 copy + changes. BTRFS also supports compression.
    • System wide flatpaks are in /var/lib/flatpak/app. Flatpak installed for one user only are installed somewhere in ~/.var. Keep in mind that home directory is not backed up by default.
    • If you can, ditch dual boot. If the reason of keeping Windows is MS Office or Adobe apps, you can install them on Wine.

      Merge “Mint” and “Timeshift” partitions.

      I thought (also most people said) keeping the Backup in same partition as root defeats the purpose of Backup and brings certain inconvenience like can’t just delete the partition. Also I don’t know if its possible to restore a backup from a partition to the same partition itself.

      Use BTRFS if you can.

      I’m aware that BTRFS has certain adavantages. But the whole BTRFS is alien to me, as I’m new to Linux. Also I assumed that BTRFS doesn’t have enough community support as ext4 is default on Linux and many people just aren’t bothered to change it.

      If you can, ditch dual boot. If the reason of keeping Windows is MS Office or Adobe apps, you can install them on Wine.

      I only use Windows for DaVinci Resolve Free. And for the possibility of requiring Windows exclusive programs in the future as I’m an Engineering Student.

      System wide flatpaks are in /var/lib/flatpak/app. Flatpak installed for one user only are installed somewhere in ~/.var. Keep in mind that home directory is not backed up by default.

      Thank You.
