I want to implement online backup for a couple of my clients. There are a few obstacles though:
The large amount of old data (over 100GB) will make this quite expensive to store online.
The slow upload speeds (1Mb) will take a long time to do the initial backup.
ISP won't be too happy with that upload.
I was thinking along the following lines:
Make a full system image (using Ghost or similar)
Set the online backup to store files changed since the image was made.
What is the best way to do this? Is there an easier method?
