[Update: I’m now researching ZFS and LVM so I’ll hold off on btrfs for now.]
AMD Ryzen 7 laptop. I may soon wipe out my Ubuntu 21.10 ext4 and do a fresh install of Ubuntu 21.10 btrfs. I’ve got a full Clonezilla clone of my system drive (including all my user data files). I’ve backed up all my user data to 2 different drives (one with FreeFileSync and one with Restic).
I’m somewhat new to Linux. What should I watch out for and be aware of when making this change from ext4 to btrfs? What subtle or not-so-subtle problems could arise when I make this change?
I mainly use Ubuntu to do simple stuff; web browsing, email, documents, spreadsheets. Nothing fancy. I’m not a coder or dev or admin.
I’ve been using Ubuntu ext4 for about 9 months; been working great. Main reason I’m switching is so I can take advantage of all the snapshot goodness offered by btrfs.
Some apps I use regularly are Syncthing (sync to my Android), Cloudberry Backup (B2) and VirtualBox with guest Windows 10 for some Windows-only apps (HDSentinel and CloudBerry Explorer). I’ve backed up a .vdi and .ova file of my Windows 10 guest (I’m assuming I can import them into my new VirtualBox on the new btrfs system).
