With hardware based compression, the compression of data occurs after we send it to the tape library\drive. Since the hardware is doing the compression we cannot report the compressed size because its happening after we write the data. We are only able to report on the uncompressed size when hardware compression is being used.
Thank you,
Collin

Hello Collin, i don't understand! you mean that i see 10Tb on commvault but the storage data can be more?
Where i can see correctly size? and check if the hardware compression are correctly use?
Hello
Thank you for your patience. The tape library GUI should tell you the size of data on the tape.
Thank you,

Native backup have full guaranteed .
No Guaranteed, If we take backup with compression (hardware/ software) not sure that how much data compressed.
It just selling strategic policy.
