Phillip,
Please report to my first post:
A LTO-3 = 100% = 567.17GiB. As LTO3 is 400G native, that is 41.8% compression, 
I mean 400G * 1.418 = 567.17GiB.

The Data on the LTO-4 tape comes from the same server, (only with more 
directories included), thus almost same data should be almost same compression, 
and I would expect it to hold twice the LTO-3 data, and thus the 100% would be 
2 * 567.17 = 1,134.34GiB. And thus the correct percentage to be shown would be 
80.53% . And that would be correct as this LTO-4 tape is not full yet.

So the problem is that Bareos assumed that an LTO-4 tape is the same size as 
the LTO-3.
