Hi Alexander,
the BRTOOLS are not aware of the file system compression of NTFS.
Therefore, from BRTOOLS point of view, you're doing a backup without compression.
In this case, BRTOOLS checks the brutto size of the database against the available freespace in the backup target location.
Updating the compression factor will only be usefull if you'd acutally use compression.
The option you used for that "-k hardware" is just not available for disk based backups and therefore ignored.
Use "-k software" instead to have the backups compressed with "compress" or "zip" or whatever tool you setup in the init<sid>.sap file.
Since NTFS file compression uses much resources (memory) on the file server and takes time, you should reconsider using it.
Instead you may consider using RMAN to backup your database.
RMAN does not only just copies the allocated blocks and leaves out everything unnecessary it also provides a pretty good built-in compression.
hope that helps,
Lars
