Release Notes: This release fixes several important bugs in the 3.0 version, making it more stable. In addition, automatic scaling of compression buffers based on compression level has been added. This improves compression ratio for the simple usage modes.
Release Notes: This release fixes several issues, including some corner case crashes and a couple of buffer overflows. Data Deduplication can now be done using blocks as small as 2KB, providing a much higher dedupe ratio than virtually any other deduplication software. Similarity based deduplication performance has been improved. Free memory detection accuracy has also been improved.
Release Notes: This release fixes a few bugs and provides several improvements in efficiency and performance. The Similarity detection effectiveness for similarity based near-exact deduplication has been improved. At the same time memory requirements for the index has been reduced. Accuracy of data partitioning between threads has been improved. Chunking and indexing performance have been improved and the KMV Sketch computation is now more accurate. This release moves all the core functionality into a shared library in preparation for an API interface that will be introduced in future releases.
Release Notes: This is primarily a Bugfix release. It fixes some crashes with invalid input and build problems on Debian6 and older non-SSE4 processors. The Min-heap based Similarity matching for Delta Encoding has been improved and made faster and more accurate. Accuracy of scalable Segmented Global Deduplication has been further improved to be greater than 95%. More testcases have been added.
Release Notes: This release adds many bugfixes and performance improvements. Accuracy in finding duplicates in Global Dedupe has been improved. SHA256 is now the default block hash algorithm for dedupe, with the ability to change it separately from the chunk verification hash. Overall, many performance improvements have been made, with better parallelism, more SSE vectorization, and faster sorting and improving the segment hash list file handling, resulting in smaller I/O and fewer random accesses. Bugs in calculating in-memory index size has been fixed to avoid overflowing free RAM and swapping to disk.
Release Notes: This release introduces a bunch of fixes and optimizations along with more tests for error conditions. Security has been improved with IPSec-style message authentication and header CRC32 checksums in plain non-crypto mode. Zlib(gzip) compression has been made slightly faster. The rolling hash has been tweaked to improve block size distribution and chunking behavior of deduplication, resulting in an improved dedupe ratio. The compressed archive version has been bumped while retaining compatibility to decompress older non-encrypted versions.
Release Notes: This is a small update release that adds a few fixes and moves to a multiplicative rolling hash as its biggest change. This change improves the hash distribution and generates better dedupe block boundaries for different types of data. This in turn improves dedupe ratio.
