Backup Exec 160,000,000,000 = 54 gigs?


I am backing up a large amount of data, over 100 gigs, to a Backup To Disk folder using BE 10D. I have a confusing problem.

BE currently states that 160,000,000,000 Bytes have been written. Using a byte converter website, that is about 149 gigs.

The disk states that only 54gigs have been written. I don't think that BE 10D has THAT good of compression.

What might be going on here?

What type of files are you backing up?  If it's all MP3 files and Divx movies, I'd be concerned.  If it's text files, a 3:1 compression ratio is nothing.  

Does the backup job verify properly and if so, what happens when you catalog the tape?  Does it report all the files on there properly?
Oh... as an example... I send information to a third party provider on a monthly basis.  I compress and encrypt the files using WinRAR 3.7x.  Last month's files were 173MB uncompressed.  The archive was 7.2MB.  That's a 24:1 compression ratio.  
Did those answer your question?

The backup files are completely corrupt. I have never seen that level of compression with BE, it is more in the 10-20% range.
The compression ratio really does depend on the type of files.  Can you give some insight as to what they are?

What do the backup logs state with regard to the job completion and verification?  Are you using any type of encryption?
