Do I Really Need to Migrate from DLT (Digital Linear Tape)? - Total Data MigrationPOLL: Does Your Company Use Linear Tape Open (LTO) For Archival Storage?There is no hard and fast rule. It depends on how often the tapes are used, storage conditions, the state of your tape heads, etc. I know some installations replace their tapes once a year. LTO tapes have a built-in microchip which stores some statistics. I have seen an expensive device which reads these statistics and give you a score as to how reliable the tape is.
When it comes to replacing tapes, just remind the bean counters how much is the failure to recover from a disaster going to cost the company. It is no good having a backup which cannot be restored because the tape is unreadable.
