Cannot backup multiple files using acrocmd

So when I try to backup more than one file by name it doesn't work. I get the following error:

C:\Program Files (x86)\Acronis\CommandLineTool>acrocmd.exe backup file --include=E:\WSUS\WsusBackups\07Oct2013\07Oct2013Export.cab E:\WSUS\WsusBackups\07Oct2013\07Oct2013Export.log --loc=E:\ --arc=Sep2013Patches --backuptype=full --progress
Invalid command-line format.
Error: 0x1510001
$module = "acrocmd_vs_37687"

Parameter 'E:\WSUS\WsusBackups\07Oct2013\07Oct2013Export.log' is not recognized.

Documentation says:
Separators
A parameter name and a value list can be separated by either an equals sign or a space character. Values in a value list can be separated by either a comma or a space character.

Examples:
acrocmd backup disk --disk=1,2
acrocmd backup disk --disk=1 2
acrocmd backup disk --disk 1,2
acrocmd backup disk --disk 1 2

I've tried multiple ways of formatting it based on what the documentation says, all with the same result.

Can somebody help me out here? What am I missing?

Thanks for the help,

James
