FAQ
2001-05.1:
archiving and backups, what is the difference? Backups, on the other hand, have a very different purpose. They are a defence against loosing data in case of hardware failure and/or hacker attacks. For example, if a hard disk crashes, the work of an entire research group of a year or more could be lost. Typically tapes awee used for this purpose as the information is stored for a limited time only before it is overwritten by a more recent version. In the past, archiving and backups have been the obligation of research groups. Through the purchase of a dedicated backup server (in essence a computer with one purpose only: providing a huge amount of disk space), we are now able to implement a much better backup strategy. Better, because it is computer–controlled and works without any human intervention, i.e. it does not depend on whether or not a person forgets to put a tape into the tape drive... It is essential to realize that the backups are over-written daily so this is not archiving which remains the groups’ and/or individual users’ responsibility. NMR tubes
