  2. Proxmox Backup Server - Wikipedia

    en.wikipedia.org/wiki/Proxmox_Backup_Server

    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 ]

  3. ZFS+ - Wikipedia

    en.wikipedia.org/wiki/ZFS+

    ZFS+ is a combined file system and logical volume manager software subsystem initially released under the Common Development and Distribution License (CDDL). It is based on ZFS, originally developed by Sun Microsystems, with proprietary data deduplication features added by GreenBytes and subsequently made proprietary for a storage system product. [1]

  4. ZFS - Wikipedia

    en.wikipedia.org/wiki/ZFS

    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.

    As the FSF (Free Software Foundation) claimed that there was a legal incompatibility between the CDDL and the GPL in 2005, Sun's implementation of the ZFS file system couldn't be used as a basis for the development of a module in the Linux kernel, couldn't be merged into the mainline Linux kernel, and Linux distributions generally did not include it as a precompiled kernel module.

  6. Data deduplication - Wikipedia

    en.wikipedia.org/wiki/Data_deduplication

    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.

  7. Kernel same-page merging - Wikipedia

    en.wikipedia.org/wiki/Kernel_same-page_merging

    KSM performs memory deduplication by scanning through main memory for physical pages that have identical content, and identifies the virtual pages that are mapped to those physical pages. It leaves one page unchanged, and re-maps each duplicate page to point to the same physical page, after which it releases the extra physical pages for re-use.

  8. GFS2 - Wikipedia

    en.wikipedia.org/wiki/GFS2

    In computing, the Global File System 2 (GFS2) is a shared-disk file system for Linux computer clusters. GFS2 allows all members of a cluster to have direct concurrent access to the same shared block storage , in contrast to distributed file systems which distribute data throughout the cluster.

  9. zFS (z/OS file system) - Wikipedia

    en.wikipedia.org/wiki/ZFS_(z/OS_file_system)

    z/OS File System (zFS) (official name: z/OS® Distributed File Service zSeries® File System) is a POSIX-style hierarchical file system for IBM's z/OS operating system for z System mainframes, a successor to that operating system's HFS. [1]
