If I read lsblk correctly, I am using ext4 for my whole drive. I have used linux for some years now, but I never bothered to learn more than “next next next done” when installing my OS.
Does BTRFS popOS allow BTRFS? Should I bother for a daily driver?
Unraid turned me on to BTRFS, but in the end, you have to want to use the features to make it matter.
Only have one HDD and using a laptop, ext4 has been working well enough so far. I only wonder if there is something else I should use for my home drive for better disaster recovery.
It really depends on the disaster. Snapshotting isn’t strong disaster recovery protection. It’s more like I’m about to do something stupid and need to undo. If you need real disaster recovery slap an NVMe in an external enclosure and sink them up occasionally. Or set up sync thing or something like that.
In practice BTRFS is a bit faster and on a Distro like Fedora or Opensuse they already integrate it to do system backups while running (copy on write).
In practice it just works and you dont use all the fancy possibilities, because a majority of the Linux world still sticks with ext4 for whatever reason, so Filemanagers and backup tools wouldnt reach everyone.
Its a perfect example of Linux slowing down itself by desperately refusing to change
- Xorg
- old Desktops
- old software, system packages, damn appimages
- no automatic updates
- ext4 instead of something modern
Ext4 is from 2008. BTRFS is even older from 2007, but was only declared stable in 2013. More innovation, more testing time, more “dont use it yet, it is unstable”. Ext4 probably never was as they didnt try that much.
