Sure the dvd may last a long time ( 100 plus years)in storage Look at how cdr and dvd are faring right now as compared to just 10 years ago. The major conundrum here is, technology is rapidly outpacing the storage capabilities. Pros: larger storage capacity due to recording procedure, and the size( length) of the tapeĬons: susceptibility to magnetic fields, fragility of the media, ( heat, cold, wearing, stretching, tearing, wrinkling, etc)Īnd lastly the magnetic fields of the recorded data itself will fade over time if not refreshed periodically. In controlled temperature environments they can last centuries.Įasily damaged by excessive heat, excessive sunlight, dirt scratches and being fragile in excessive cold. Much lower costs highly reliable, and relatively immune to magnetic corruption, searchable, and much higher speed. Optical media such as blueray for long term storage, The problem with backing up large amounts of data is that media size is a problem.Īnd what will the long term reliability of the storage media be? Numerous shareware utilities ( pkzip, / pkunzip, 7 zip, etc) were available for this.īut many os’s come with their own backup programs that give you the option of file compression. This 3 step process dramatically reduced the size of the file.īut like i said earlier, it might not be accurate because im an old fart□ Translation to machine code, then to binary for storage by the compression software. Leaving a number representing what it was. Its been a very long time since ive studied compression□ but from what i understand from classes ( over a half century ago)!Įarly compression was removing all spaces, tabs, and indents, and paragraphs. Providing your data is not corrupted compression is not an issue. Optical media ( providing it was stored in a cool dry place) last many times longer and by far much more economical. Its one of the reasons i quit using them. Unless you got one with direct drive capstain you had to deal with stretched belts and dry rot. It was crucial to keep the heads, rollers, and capstan clean. Tapes themselves were susceptible to magnetic fields and could degrade over time, but usually failure resulted in wear and tear. While they did indeed store a large amount of data they were damn slow to access. You could also use the ide to sata adapter. They were not searchable like other media. The ide ones often worked with windows but usually you had to install a driver to even detect them.Įven when they were detected by bios they could only be accesses through the backup and restore software. Some drives you could get with the ide interface but most were scsi. Tape drives are literally went on their way to the dinosaurs.
