DD prevents bit-rot related errors with it's garbage collection (no other vendor does this that I know of). This makes the DD arciver interesting as a solution?
Tape is more reliable with the caveat, it's written to at the minimum speed of the tape format or greater, and that the tape is stored in the appropriate climate controlled room. Which without doing those two conditions alone, you have just reduced relibablity by greater than 25%.
Perhaps the cost of tape's $$/PerGB is lower, but that doesnt account for the library itself, and moving to newer tape formats every 3 yrs, let alone the labor costs of managing tape daily, and during tape technology refreshes...
