VXA
Encyclopedia : V : VX : VXA : VXA
VXA is a tape backup format originally created by Ecrix. Since the merger between Ecrix and Exabyte, VXA is produced by Exabyte Corporation.
Exabyte and Ecrix describe the data format as "packet" technology as opposed to "linear" technology. The claim is that this gives better reliability and error recovery as well as being able to adapted to different data speeds.
The VXA format competes mainly against the AIT, DLT, LTO, and DDS formats.
