![]() ![]() ![]() ![]() It creates two copies of metadata and verifies the checksums during each data read process to detect corruption. If the database gets corrupted or any other issue occurs with your data, you can browse the snapshots like a regular directory and easily restore a previous copy of a file when the snapshot was taken.īTRFS employs checksums for maintaining the metadata and data. The snapshots are lightweight and copied to the backup destination. It offers a powerful snapshot feature, which creates point-in-time read-only copies of the entire file system. Implementing the BTRFS file system in Synology NAS RAID volumes brings multiple benefits to its users, including: Designed to address the limitations of previous file systems like ext4, the BTRFS file system has several benefits listed below. Separate commands in BTRFS carry out other filesystem tasks like scrubbing or balancing.īased on the COW principle, it writes new data to a new location whenever data is modified instead of overwriting the existing data. The file system can carry out multiple filesystem-level tasks, such as resizing, level setting, displaying space stats (used space divided by usable space), and defragmentation. The file system combines the functionality of a RAID array manager, a logical volume manager (not Linux's ideal LVM), or more. It is usually pronounced as better F S or butter F S. It is based on the copy-on-write (COW) principle. What is BTRFS?īTFS (B-TREE File System) is a new-generation file system in the mainline Linux kernel. However, you need first to understand how the BTRFS file system works and then take the right approach for data recovery. Despite these features, there are chances where you may lose access to your files stored on this file system.įortunately, there are ways to restore your BTRFS file system data. It offers fault tolerance, volume management, and data protection to maintain data integrity. The file system intends to address the lack of features like snapshots, checksums, pooling, and multi-device spanning in other Linux file systems. BTRFS is a modern file system used by some selected Synology NAS models and several other brands. ![]()
