Hi Dominic, Have you looked at Box Backup? It was designed for this
situation. rdiff-backup can do it if you mount an encrypted filesystem
over the network, but it's not easy and I don't think it's secure.
Otherwise, I think Duplicity (or possibly Amanda with encryption) is
your best bet. Cheers, Chris.
Thanks Chris, Box Backup looks very neat. But does it store old copies
of files in full, which will eat a lot of server storage space for 2GB
email files and the like? Or is it using rdiff-backup (or duplicity or
rdiff or some equivalent technology) under the hood and storing file
histories by creating [forward or reverse] file diffs (deltas)? Is it
also optimised (like rdiff-backup and rsync) for file transfers i.e. it
transfers a diff not the whole file?
Regards
Dominic
