Why use the BTRFS File System

UPDATED: December 9, 2018

When dealing with large-scale data storage, organizations require a solution that prevents data corruption, while providing scalable and flexible backup tools. The next-generation Brtfs file system brings these tools to servers, allowing businesses and companies to reduce maintenance overhead and efficiency store their data.


What is a Btrfs?

Btrfs file system is designed to meet the expanding scalability requirements if large storage subsystems. Besides, the Btrfs file system uses a B-trees in its implementation.

Btrfs file system provide the following important features:

-Copy-on-write functionality: This functionality allows users to create both writable and readable snapshot. Besides, the snapshot allows roll back the file system to a previous state.

-Has a checksum functionality that ensures data integrity

-Transparent comprehension that helps in saving disks by creating two copies of metadata.

-Has an integrated logical volume. This allows you to implement RAID system on your storage.

-Has a transparent defragmentation that help improves performance.


What are the benefits of using Btrfs?

Implementing Btrfs file systems on any network attached storage has various benefits to organizations including.


Metadata Mirroring

In most cases if not all, storage systems keeping metadata intact is essential since it includes information such as access permissions, filenames location, and folder structures. Btrfs is capable of storing two copies of metadata on different volumes. This allows easy data recovery whenever the hard drive suffers from bad sectors or is damaged.


Btrfs file self-healing

In traditional storage, the system might experience errors that go unnoticed, hence, it may result in corrupt data being provided to an application with no warning or error messages. In order to avoid such errors, Btrfs offers checksums for metadata and data, generate two different copies of the metadata and then verifies it the checksum during any reading process. Once a mismatch is discovered, the Btrfs file system is capable of auto-detecting corrupted files with mirrored metadata and recover broken data using a supported RAID volume.


Data Protection and Snapshots

This file system has a powerful snapshot feature; that allows you to create a point-in-time copy of an entire shared folder. In that manner, if there is any human error, you can easily restore the data back to the previous time at which the snapshot was captured. Additionally, taking snapshots consumes a small amount of space while at the same time exerting slight control on system performance, thanks to the Btrfs copy-on-write architecture.


Efficient Drive Storage

Compared to an ext4 volumes, Btrfs file system does not require a double storage space for drives file versioning and history data. Besides, it assist you in retaining historical versions of the files when using the drives without having to worry too much about the storage space.

Data consistency of Backups

Traditional data backup procedures requires a lot of time to copy files and data from one drive to another, possibly leading to unreliable data if files are modified during the backup process. Notably, Btrfs solves this problem by taking snapshots before any backup process starts and then copying then copying the snapshot data to the backup destination. With Btrfs, when moving files, you need not to worry about files being modified or deleted while being moved to a new location.


Quotas for Shared Folders

When using a Btrfs file system, you can specify a storage limit for an individual shared folder. Thus, the storage space is not consumed by any other particular shared folder. This is assists when multiple teams or departments store files on the same file server.



Btrfs offers better service than ext4. Besides, it addresses the challenges of scalability and redundancy that is experienced by some of the file systems. Even more, the snapshot capability allow this type of file system to gain fame among most users since it provide a smooth flow of moving files from one drive to another. Moreover, the file system is stable and can be used in large data organizations.
