This is somewhat a continuation of my related failed question. I've decided to go with a filesystem approach rather that the whole disk in one chunk. I'm wondering what the best way to do this is. I'm thinking about extending my SyncBackSE backup to my whole NTFS partition. Would there be any downsides to this or a better way to do it?
Other stuff:
The hard drive I'm backing up to is a 160 GB external that has one big NTFS partition. Since I'm trying for a mirroring strategy, I might redo the partitions to match my notebook's 160 GB drive (10 GB ext 3|~512 MB linux-swap|138.55 GB NTFS).
Also, if no multi-platform solutions happen to be part of the answer, I'll be opening up another question dealing with this in Linux (which could probably easily backup both ext3 and NTFS).
