How do I get this working? - Empty Download File - Possible Bug

Hi,

I believe I have installed everything correctly, but can't get this module to work. Can someone please help?

I uploaded the module into my sites/all/modules directory

Tar.php was present already.

I downloaded PEAR from the website as directed and put the pear.php file in the module directory. I even tried putting the entire PEAR package in the directory.

I defined the paths to both of these.

I ran a test and it lists all of my files in the directory I defined for backup (e.g. /sites).

When I do a "Backup" it just downloads an empty file.

Periodically I'm also getting this error when saving settings:

* warning: filesize() [function.filesize]: stat failed for /backup.tgz in /nfs/c03/h04/mnt/49414/domains/mattoden.com/html/sites/all/modules/backup_files/backup_files.module on line 216.
* warning: fopen(/backup.tgz) [function.fopen]: failed to open stream: No such file or directory in /nfs/c03/h04/mnt/49414/domains/mattoden.com/html/sites/all/modules/backup_files/backup_files.module on line 220.

ANY IDEAS?

Thanks,
