Tape full usage

We are using 1.6TB ultrium tape.When i format it shows 800GB as full capacity.BUt it holds as large as 1400Gb Data.What is the concept behind that?



Re: Tape full usage

It depends on the hardware compression. 800GB is the guaranteed capacity, 1600GB is the capacity if you assume a 2:1 files compression. If the files you re backing up are already compressed, you're not going any further than 800GB. 

Some files can get also a compression higher than 2:1.
