    Default Btrfs / Snapper: Amazing Stuff!

    I gave btrfs a try when assembling a small desktop with a i3-4130 with 8 GB RAM and a WD20EZRX 2 TB 'Green' HDD. I did a LEAP 42.1 default install and gave it to a Linux newbie. Performance of btrfs was poor and it did not work out at all: https://forums.opensuse.org/showthre...orrupted-BTRFS

    Now I gave btrfs another try on a i3-4130 with 16GB RAM and a SSD 850 EVO 250GB. Installing Tumbleweed on the machine with doubled RAM and SDD instead of HDD resulted in a totally different experience during the last year:




    Current status after running some massive 'zypper dup', deleting all but the last snapshot and running btrfs-balance.service:

    Code:
    linux-udd7:~ # btrfs filesystem usage /|head -6
    Overall:
        Device size:                  40.00GiB
        Device allocated:              7.54GiB
        Device unallocated:           32.46GiB
        Device missing:                  0.00B
        Used:                          6.92GiB
    linux-udd7:~ #
    Given this pleasant experience I decided to further maintain the system as a backup and gradually add the software installed on the primary system using ext4. When done I plan to use btrfs as the primary system and ext4 as a backup.

    I was not an early adapter of btrfs, but since I have my current laptop I've used it without any issues. And I do use the rollback feature a lot: install software to help support others, when done, rollback and I have my own clean TW back.

    That made me try 'snapper rollback 2'. After rebooting changes made to network configuration were perfectly undone without any hassle whatsoever.

    I will speed up my efforts to fully configure btrfs backup system and switch to using it as my primary system.
