Every Not Forgotten legacy product is built with Library 2.0 technology, designed to keep legacies secure, discoverable and accessible for generations. All our products are treated to the same Preservation Protocols. We build archives to Library of Congress standards, which means we keep three copies in three locations on three types of media. We update technology formats regularly and monitor all copies of each legacy for digital decay.
Format obsolescence is the inability to access digital data due to hardware and software obsolescence .
Data rot destroys all media
Together these threaten memory preservation.
Digital Decay occurs in multiple ways and is the "Natural Death" and "Outside causes". When digital files spontaneously and quickly decompose or become corrupt. can occur anywhere from the host to the storage.
Natural Data Rot
◉ Type 1 Format : Magnetic type. Video cassettes, floppy discs, audio tapes. Life Expectancy: between 10 and 20 years.
◉ Type 2 Format : Computer Gear. Flash memory, Memory cards, USB flash drives, solid-state drives, feature phones, mobile/ smartphones, computers, PDAs, digital audio players, digital cameras, synthesizers, video games. Life Expectancy : The charge will last 10 years then its leaking.
◉ Type 3 Format: Optical media, such as CD-R, DVD-R experience digital decay from the breakdown of the storage medium. CD/ DVD. Life expectancy is 2 to 25 years.
The “cloud” is still just physical servers with physical disks. They’ve got the exact same issues you’d have if running your own server.
Outside causes
◉ Deliberate destruction malware and virus
◉ A lifetime of crash & bug destroy data
◉ Silent corruption on cloud servers is "widespread" - Data Rot on the Rise
◉ Silent data corruptions are becoming a more common phenomena in data centers than previously observed.
◉ Silent data corruption, or data errors that go undetected by the larger system, is a widespread problem for large-scale infrastructure systems.
◉ This type of corruption can also result in data loss
◉ Format updates destroy data
◉ "Hard use" / frequency of use destroys data
