The mechanism has features that other file systems with snapshot functionality don’t own.Ī great many snapshots can be taken without degrading performance with the ZFS file system while allows snapshots to be used prior to risky system operations and software changes, or an entire production file system to be fully snapshotted several times with a single hour. The complete control of the storage system is used to ensure that every step, no matter related to file or disk management or not, is verified, confirmed, corrected if necessary, as well as optimized in a way that storage controller cards and separate volume and file managers can’t achieve.Īs for ZFS file system advantages, also, it contains a mechanism for dataset and pool-level snapshots and replication, including snapshot cloning that is described by the FreeBSD documentation as one of its most powerful features. The ZFS file system is designed to make sure, subject to suitable hardware, that data stored on hard disks can’t be lost due to physical errors or wrong operations by the hardware or OS, or bit rot events and data corruption that may happen over time. Thus, the ZFS file system has complete knowledge of both the physical disks and volumes, including their condition/status and logical arrangement into volumes, as well as all the files stored on them. The other aspect means the management of files saved on those logical block devices, a file system, or other data storage.īe different from other storage systems, ZFS is unusual for it unifies both of the roles and plays as both the volume manager and the file system. One aspect refers to the physical volume management of one or multiple block storage devices like hard drives and their organization into logical block devices as seen by the OS, which usually involves a volume manager, suitable device driver, RAID controller, or array manager. There are two aspects for storage managing. originally developed the ZFS file system and Solaris operating system was first used with it. Q: What company originally developed the zettabyte file system and what OS was first used with it?Ī: Sun Microsystems Inc. OpenZFS is widely applied in Unix-like systems. OpneZFS manages and maintains the core ZFS code while organizations making use of ZFS to maintain the specific code and validation processes needed for ZFS to integrate within their systems. In 2003, OpenZFS was founded to coordinate the development of open-source ZFS. In 2010, the illumos project forked a recent version of OpenSolaris to continue its development as an open source project including the ZFS file system. From 2005 to 2010, the ZFS opensource version was ported to Linux, Mac OS X (continued as MacZFS), as well as FreeBSD. Later, Oracle Corporation acquired Sun in 2009/2010 and put Solaris under a closed source license. Large parts of Solaris OS including ZFS were released under an open-source license as OpenSolaris for about 5 years since 2005. It began as part of the Sun Microsystems Solaris operating system (OS) in 2001. ZFS file system, previously known as zettabyte file system, is a kind of file system with a volume manager.
