![]() ![]() In fact, users will save more space when using Btrfs’ transparent compression. When copying a file, Btrfs does not write new data until you actually change the old data, saving space. Corrupt data is never given to your programs, and it won’t replicate into your backups to be discovered another day (or year).ītrfs uses a “copy-on-write” model: your data and the file system itself are never overwritten. Fontforge faster turn off verification#Btrfs safeguards your data with checksums, and performs verification on every read. Data can be corrupted by a multitude of physical factors, even cosmic rays from the sun! Before an SSD fails outright, often it will return either zeros or garbage, instead of your data. Btrfs solves this problem by avoiding it.Īs a techie, you may have heard of bit rot, and memory bit flips. The previous default layout placed constraints on disk usage that can be a difficult adjustment for novice users. The switch to Btrfs will use a single-partition disk layout, and Btrfs’ built-in volume management. What does this mean for me?ītrfs is a stable and mature file system with modern features: data integrity, optimizations for SSDs, compression, cheap writable snapshots, multiple device support, and more. Btrfs will replace ext4 as the default filesystem in Fedora 33. The Fedora Project is changing the default file system for desktop variants (Fedora Workstation, Fedora KDE, etc), for the first time since Fedora 11. Changing the default file system is not a change to make casually. ![]() Whether it’s source code for the next big release, family pictures, a music library, or anything else, you want it to be safe.
