It supports fast incremental update by adding only files whose last-modified date has changed since the previous update. It compresses using deduplication and several algorithms (LZ77, BWT, and context mixing) depending on the data type and the selected compression level. To preserve forward and backward compatibility between versions as the ...
In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.
Starting from version 1.3.2 (October 2017), zstd optionally implements very-long-range search and deduplication (--long, 128 MiB window) similar to rzip or lrzip. [ 6 ] Compression speed can vary by a factor of 20 or more between the fastest and slowest levels, while decompression is uniformly fast, varying by less than 20% between the fastest ...
FreeArc uses LZMA, prediction by partial matching, TrueAudio, Tornado and GRzip [7] algorithms with automatic switching by file type. Additionally, it uses filters to further improve compression, including REP (finds repetitions at separations up to 1gb), DICT (dictionary replacements for text), DELTA (improves compression of tables in binary data), BCJ (executables preproccesor) and LZP ...
The Data Domain Corporation was founded by Kai Li, Ben Zhu, and Brian Biles in 2001 as a company specializing in target-based data deduplication products for disk-based backup. [ 1 ] [ 2 ] [ 3 ] Hugo Patterson joined as chief architect 3 months after initial funding.
Proxmox Backup Server (short Proxmox BS) is an open-source backup software project supporting virtual machines, containers, and physical hosts. [3] The Bare-metal server is based on the Debian Linux distribution, with some extended features, such as out-of-the-box ZFS support and Linux kernel 5.4 LTS. [4]
In August 2018, Pure Storage made its first acquisition with the purchase of a data deduplication software company called StorReduce, [32] for $25 million. [33] In April the following year, they announced a definitive agreement for an undisclosed amount to acquire Compuverde, a software-based file storage company.
ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
