Btrfs Filesystem
Btrfs is a copy-on-write (COW) filesystem that focuses mainly on ease in repair and administration. Btrfs eliminates the risk of corruption of data and inaccuracy in data. It is extent based filesystem with huge file size support up to 2 powered 64 (2^64) bytes. It has dynamic inode allocation because of which we can create as many files as we want until we have free space. Also, its name comes from B-trees, which the filesystem uses to store internal file structures for efficient processing of files.
Note:
- After Btrfs filesystem gets fully developed or maybe in a few years when all its features are stable, Ext4 might get replaced by it.
- Creating a file or directory with the name ‘.’ and ‘..’ in both the Ext4 or Btrfs filesystem is not possible.
Difference Between Ext4 VS Btrfs Filesystems in Linux
In simple terms, the filesystem is a database containing physical locations of files and data for easy retrieval at the time when it is needed. With the help of the Filesystem, the operating system controls how the data is stored and retrieved. File System usually contains files separated into groups known as directories which can hold files and furthermore directories in them. Also helps the system to store the files in the most efficient way possible.
Example:
- Ext4 and Btrfs Filesystems are pretty much well known for their performance in Linux environments.
- NTFS and FAT are known in Windows environments.
