Question about ZERO Compression Backups : Are they 1:1 ?

Hi Everyone,

With Acronis 2010 when compression was set to NONE, the backup was equal to the size of what was being backed up.

Now, with 2011, with NONE set for compression, my .tib file is HALF of what the source is (even though the Estimated Backup Size given for the backup before the process begins ='s the source)

What am I missing? Does backing up a 64 bit Drive differ from a 32 bit drive?

Thanks,

Jeff
