DDS stands for digital data storage, which is a data format used for backing up computer data on magnetic tapes. DDS tapes are based on the earlier DAT or digital audio tape technology created for the music industry.

In 1989 Hewlett Packard and Sony came up with the DDS format for storing data on the tape cartridge. The original DDS drives used DAT tape cartridges. DDS tapes are 3.8 millimeters wide. Originally, the tapes were 60 or 90 meters long, but the length has increased over time. A DDS tape drive uses the same process used by a VCR to record, called helical scanning.

After 2000 passes or 100 backups, DDS cartridges need to be removed from the system as they will be worn out. The life expectancy for these tapes is at least 10 years.

A very good alternative to the DDS tape format is VXA. VXA is the only tape format that uses a patented packet read and write technology that eliminates the worry of non-recoverable data.

VXA tapes offers many advantages over DDS tapes including the increased reliability of packet technology. Other advantages of VXA over DDS tapes include more capacity, faster backups, and an affordable price.
