Introduction:
BTRFS is a modern copy on write (COW) filesystem for Linux aimed at implementing advanced features while also focusing on fault tolerance, repair and easy administration. Its main features and benefits are:
- Snapshots which do not make a full copy of the files
- Built-in volume management, support for software-based RAID 0, RAID 1, RAID 10 and others
- Self-healing – checksums for data and metadata, automatic detection of silent data corruptions
In some cases, we see that users simply start installing BTRFS because they think it’s new, fast, fancy, the next big must-have, or whatever. That’s a link to trouble! If you do not have any clue about the four points described beforehand, you should not use BTRFS, at least not without first reading about what exactly it is and how it basically works, as it is different from traditional file systems in many ways.
Tips and Tricks:
To handle BTRFS there is a nice GUI tool you can install:
