BSD Operating Systems

The first BSD/OS, originally called BSD/386 was a proprietary version of the BSD operating system developed by Berkeley Software Design Inc. (BSDi) by members of the Computer systems Research Group at the University of California in Berkeley. BSD/386 a UNIX variant was released in 1991 in particular for use as an internet server on PC compatible systems running Intel 386 or later processors.

BSD has a reputation for stability, making it perfectly suited to run in a server environment. BSD/386 was sold with a licence and support, which included source code. The name was changed to BSD/OS after support was added for running the operating system on Sun SPARC based machines. This paved the way for open source versions of BSD, which are in common use mostly for running server systems. There are many active variants which may be seen for data recovery, the best known of these being FreeBSD, OpenBSD, NetBSD and DragonFly BSD with many more being developed, some based on the aforementioned versions. Apple OS X is uses Darwin, which is derived from FreeBSD.

BSD Data Storage

Most variants of BSD include many features usually found at the enterprise level, including iSCSI, filesystem journaling, logical volume management and the ZFS filesystem, which is now used by default. The Logical Volume Manager (LVM) is based on the tools developed for the Linux operating system. This allows a BSD to be set up as a RAID server also allowing data storage to be presented in the form of a SAN or a NAS. It is normal for most versions of BSD to also support a large number of “foreign” filesystems, including FAT, NTFS and Linux Extended FS.

Uses of BSD Operating System

BSD is in use by many large multinational corporations in a variety of different applications, from workstations to server systems. The most common uses are for applications such as data storage solutions, including NAS and SAN systems and firewalls. BSD variants are seen in a number of devices as an embedded operating system, such as the Playstation 3 and 4.

BSD and Data Recovery

Thus far all BSD based systems we have seen requiring data recovery, have been SAN servers, where the data has become inaccessible, usually due to physical disk failures, corruption of a file system, or user error. These have all contained data chunks pertaining to either NTFS, Linux Extended FS, HFS+ or XFS data volumes, from which data recovery has been successful.
