I'm relucant to even say, because you are heading in an unproductive
direction.  But here goes: a compressed file without checksums starts
with 0x78 and a compressed file with checksums starts with 0xd6 or 0xd7.
See lib/BackupPC/FileZIO.pm.

The file sizes in the example you cite suggests the first has checksums
and the second does not.
