Hello to you all! I am a new user to the NSLU2 and wonder about the disk-to-disk backup feature. I have attached two HDs 160 GB, formatted Ext3 I have scheduled a backup job for disk backup (disk 1 to disk 2) For around 50 GB it lasted somewhat 4 hours (disk 2 was blank before)... So when i re-do the disk-to-disk job next friday, will it do a whole copy again, or does it do something like synchronizing which would fasten the process?! Greetz, Alex.
