I have tried several backup solutions for my data and none of them was good enough.

I basically want to make a copy of my files to an attached USB Drive from time to time. I don't mind starting my backups manually, since the USB Drive is not always connected.

My problem is that my data contains a lot of files (a huge amount), so backing up takes forever (more than 20 hours).

Using "rsync" an other similar solutions is not working because the I/O needed to check the file for changes takes longer than the time to actually copy it.

Any suggestions?
