Doing a backup took over 7 hours - please help - [SSU]

[nisdats]

I am running a heavily modified 1.3.8 with the SSU URL mod. My backup took over 7 hours to finish through a fast DSL connection. The problem is the SSU mod dumps useless empty folders (hundred thousand of them!) in my CACHE folder. I do have lots and lots of categories b/c my shop is auto parts so I have separate categories for all makes models years..

The empty folders have names like 1-through-9 and then each one has 1-9 inside it and then AGAIN 1-9 inside THOSE and then even deeper, they all have wierd names like "dsf3D97if" or "ab45" inside them!!! Thousands and thousands and thousands of empty folders. This is AFTER I cleared the SSU cache in Admin.

The folder where this mess is public_html\cache\ssu\pc\ and this part took 6.9 hours and the rest of the backup was done in less than 10 minutes!!

Please Help if you know anything about this. I am attaching a picture of the backup folders... Thank You in advance for ANY HELP about this. SSU is a great mod and I would like to keep it but can't afford 7 hours to do a backup..

Respectfully,

Igor
