Secure Data Archiving Methods Today

Many industries require completely secure data archiving solutions

. Software , hard drive backups, and online data archiving solutions will never be as safe and secure as archiving methods like DVDs, which cannot be accidentally overwritten and cannot be accessed online by hackers. Hard drive archives are responsible for the most lost archives, with hard drive crashes accounting for most of the catastrophes. Online and software data archives are the most susceptible to privacy breaches due to hackers and viruses. The most secure methods utilize Ultra Density Optical (UDO), Digital Versatile Discs (DVD), Blue Ray Discs (BD), or Magneto-Optical (MO).

Ultra Density Optical (UDO) WORM storage is the only kind of archiving solution that was designed specifically for archiving purposes (DVDs and Blue Rays were originally designed for the entertainment industry, not for legal archives or medical records databases). This type of high-density data archiving solution relies on a 5 and one-fourth inch optical disc with a true WORM (Write Once Read Many, which means you can write only once and read it many times, meaning you can't accidentally write over it). UDO can also be purchased as Compliant WORM or R/W (which means you can rewrite over the data). UDO can be used to store both data as well as video data. UDO has a higher cost than DVDs or Blue Ray Discs, but has a higher storage capacity per disc than either.

Digital Versatile Discs (DVDs) are a safe and widely used type of data storage because they are secure. DVDs provide secure WORM memory (WORM stands for Write Once Read Many, which means that the DVD can be written by the DVD burner only once, and you can read it many times; this ensures that you don't accidentally write over it).

Originally developed to store movies and music that is written onto the disc at a factory, DVDs can now be burned with DVD and CD burners quite easily. DVDs are very inexpensive, although their storage capacity per disc is lower than that of other types of archiving devices. DVDs offer only 4.7 GB of storage per side (or 9.4 GB per disc), which is much lower than Ultra Density Optical discs (UDOs offer storage of 60-120 GB per disc) or Blue Ray Discs (BDs offer 25 GB storage capacity per disc, or 50 GB per disc).

Blue Ray Discs (BD) offer the best combination of high-density storage and moderate price in the data archiving industry currently. They are designed with the same 120 mm flat disc format as a typical DVD, but offer more than five times as much storage space in the same sized disc (a BD has 50 GB per disc, and a DVD has only 9.4 GB). This type of optical disc is highly efficient for data archiving.
