It all depends on the type of media you are using.  IBM's 3592 holds 300gb
native and compressed it can contain almost 1TB.  STK 9840 holds about
20GB native and they figure compression at 4:1 so 80GB compressed.  a
3490E holds about 2.5gb compressed.

Re: Tape  Questions






Hello All,

    I have a question is there a rule of thumb for how many tapes will
be used, when using TSM.  I heard that for every Terabyte that is backed
up, 1000 tapes could be used.  I was just wondering, if anybody knew
something different.  I keep 2 versions for 7 days

Thanks

James
