Packet technology is a revolutionary technology for backing up data using a tape backup system. Packet technology uses digital packets-similar to the packets used to transfer data on the Internet. Unlike conventional tape backup technology, these packets do not rely on perfect head to tape alignment to be read.

The biggest problem facing conventional tape backups is the head to tape alignment which VXA has completely eliminated. It changed the way tape backs read and write the data with the digital packets. Data is broken into small packets with each packet being assigned its very own address as well as its own error correction code also referred to as ECC.

Strings of data are then written into each packet. During each drum rotation the drive head records a pair of alternate azimuth packets. The secondary or trailing head then compares the information on the tape with the information on the hard drive. If it detects any errors it rewrites the data correctly, saving time during the backup process. Other tape drive formats write the entire backup again or rewind the tape and has to start writing all over again if an error is detected.

Unlike other tape backup technology that allows a certain percentage of write errors to occur, VXA packet technology's "perfect write" system has a zero tolerance for errors. The second read head validates that the data packet was written correctly and ensures this by sending bad packets back the write head to be re-written on the fly.

Today's technological demands far exceed those of just a decade ago. We are using faster equipment and more people use electronic data more than ever. Massive storage capabilities combined with accurate information storage are vital to commerce and communication in our modern world.

Not only is packet technology more reliable than anything the industry has seen, it is also more affordable and it gives you more choices when it comes to choosing tape sizes. You can pick a VXA packet technology tape backup system that fits your needs and budget.
