encrypted destination

[Michael]

Hello

I am looking for a method/feature to rsync my files and store them
encrypted. While searching for a solution I found some postings about
--source-filter and --dest-filter options but these seem to to be
implemented.
Of cause I could encrypt and them rsync but this costs double of space
and a lot of CPU Power. So my questions is how do the experts this?
a) is there an option to encrypt the destination file
b) if not what would be a professional approach to "store" data
encrypted on an external space?

Thanks a lot
Michael
