Timemachine Backup doesn't work

[jobooo]

Hello!

Can anybody help me out with my timemaschine troubles? I have a new USB device, when I start the first backup run the timereaming is increbly high. During an overnight run there where just 18 GB from 500 GB saved.
I have already checked both disks and permission with the disk utility tool.

I know that the first run takes a lot of time but it would be more than a week.
Any ideas?

Thanks in advance!

my 1st time machine backup was almost 24 hours only time i've left mcbpro switched on overnight....thats was only approx 150-250 meg via 500 meg external hdd/aesextreme/wifi

good news the backups since are much smaller and very fast...5-10 mins
