ASKER
where i check the compression level????
On media (or storage, my backup exec is not in english), search and select one tape you have used, left button, properties.

i see just that hardware compression is enable
But this compression depends of data. You are using cartridges that could be store 1,6Tb but real capacity is only 800gb. Since 800 is less that your total data volume, depends how many can be compressed this data.
Your backup can not be fitted on only one cartridge because your compression rate is below 2:1, you can check on one cartridge you have used, here can obtain statistics about cartridge usage, free space and compression rate. You can check your compression is below 2:1 and this causes you need two cartridges.

Check on tape what is compression level, because 1,6Tb is very optimistic compression rate (2:1), on my fileservers compression rate is 1,35:1.
