Btrfs RAID Recovery with NAS Data Recovery Software [Solved]

What Is Btrfs

Btrfs, also known as the B-Tree file system, was created to address issues that arise frequently in enterprise storage systems, such as fault tolerance, complex data management and protection. As a modern file system that has been developed by a number of different parties, it is now supported by multiple Synology NAS models.

Benefits of Btrfs:

Stability:

Over the past few years, Btrfs has been greatly improved. Now it is mature enough to be used in most simple cases, even for different RAID levels. The latest Btrfs version can fix typical errors in a Btrfs Raid-5 file system.

Enhanced data availability:

Maintaining metadata integrity is critical in any storage system because it contains important data such as folder structures, filenames, access permissions, and the location of each file. In the storage process, Btrfs stores two copies of metadata on a volume, which offers help for data recovery if the hard drive is damaged or has bad sectors.

Data protection and snapshots：

The snapshot feature of the Btrfs file system allows you to create a real-time copy of a shared folder. As a result, you can easily recover lost data to the point when the snapshot was captured if important files are deleted or lost.

Efficiently save drive storage:

For Drive's file versioning and history data, Btrfs does not require double the storage space. When you use Drive, you can keep historical versions of files without worrying about running out of storage space.
