DragonFlyBSD's HAMMER2 File-System Receives Enhanced Improvements and Initial Recovery Support

The HAMMER2 file-system from DragonFlyBSD continues to see new improvements and developments, according to Phoronix. Known for its support of online deduplication, clustering, multiple mountable file-system roots, snapshots, compression, encryption, extensive checksumming, and other features, HAMMER2 has evolved over the past decade and recently received further enhancements.

Matthew Dillon, the lead developer of DragonFlyBSD, has been working on refining HAMMER2 for the next release of the operating system. In the past few days, there have been notable updates to HAMMER2, including improvements to its CPU performance and the addition of a new “hammer2 recover” directive. This recover support allows for the recovery or undoing of single files and provides preliminary support for recovering entire directory structures.

Overall, it’s interesting to see development of alternative file-systems such as HAMMER2.
