Veritas Software Corporation was an international software company that was founded in 1983 as Tolerant Systems, renamed Veritas Software Corp. in 1989, and merged with Symantec in 2005. It was headquartered in Mountain View, California. The company specialized in storage management software including the first commercial journaling file system, VxFS, VxVM, VCS, the personal/small office backup software Backup Exec and the popular enterprise backup software, NetBackup. Veritas Record Now was an early CD recording software. Veritas was listed on the S&P 500 and the NASDAQ-100 under the VRTS ticker symbol.

Tolerant Systems was a company founded in 1983 by Eli Alon and Dale Shipley (both from Intel) to build fault-tolerant computer systems based on the idea of "shoe-box" building blocks. The shoe box consisted of an OS processor, running a version of Unix called TX, and on which applications ran, and an I/O processor, running a Real Time Executive, developed by Tolerant, called RTE: both processors were 320xx processors. The system was marketed as the "Eternity Series."

The TX software gained a level of fault-tolerance through check-pointing technology. Applications needed to be fortified with this check-pointing to allow roll-back of the application on another processor if a hardware failure occurred. Tolerant also developed a forerunner of today's RAID systems by incorporating a journaling file system and multiple copies or N-plexing the disk drive content.
