    Ok, I don’t get it. Can you explain it to me?

    [–] 0x4E4F@infosec.pub 53 points 1 year ago (19 children)

    Timeshift works only with BTRFS subvolumes, thus, if you wanna have backups (snapshots), you have to have subvolumes and not install in the root of a BTRFS filesystem πŸ˜”.

    Timeshift

    Oh okey so if I have Snapper already, nothing I need to worry about?

    [–] valveman 3 points 1 year ago (1 children)

    Snapper also uses btrfs subvolumes to create snapshots, so if you did create them during your installation process, nothing to worry about.

    I don't remember if there is a way to create them after the installation, neither if it's a tough process tho. I used to simply reinstall when I messed up with the subvolumes.

    [–] backhdlp@lemmy.blahaj.zone 2 points 1 year ago (1 children)

    sudo btrfs subvolumes create /path/to/subvolume

    If you don't configure anything, root will already be a subvolume.

    If you wanna make a used directory a subvolume, you have to move the contents first, and move them back after creation.

    The only thing that takes time here is the move

    [–] 0x4E4F@infosec.pub 1 points 1 year ago* (last edited 1 year ago) (2 children)

    Yeah, but Timeshift uses the Ubuntu style subvolume naming, @ for root, @home for /home, so you have to create them that way, otherwise, it won't work. It can work if you tell it to ignore home, but checks for @ as root on start up.

    [–] backhdlp@lemmy.blahaj.zone 2 points 1 year ago (1 children)

    Wasn't aware of that, using snapper for my snapshotting needs.

    [–] 0x4E4F@infosec.pub 1 points 1 year ago* (last edited 1 year ago) (1 children)

    I haven't tried it. Does it have like daily, weekly, monthly snapshots setup?

    [–] backhdlp@lemmy.blahaj.zone 2 points 1 year ago

    You can have hourly, daily, weekly, monthly and yearly. I also use snap-pac to make snapshots before and after pacman transactions.

    Check out https://wiki.archlinux.org/title/Snapper

    [–] domi@lemmy.secnd.me 2 points 1 year ago* (last edited 1 year ago) (1 children)

    Check out Btrfs Assistant. It does what Timeshift does with a similar UI but works with any subvolume layout.

    Hm, will check it out, thanks for the suggestion πŸ˜‰.
