Encrypting backups with one's gpg public key for fun and profit :-)

As part of my diseba project, I'm looking at ways to implement a secure backup on a remote machine. It appears that there is a simple way to ensure that the backup can only be read by yourself: encrypt it with gpg using your public key (gpg --encrypt --recipient is your friend). Only you with access to your private key can decrypt the backup. Of course, as a good friend told me, you'd better save your private key in a safe place outside your backup! :-)

Such a system could be implemented in existing softwares like backup2l or BackupPC.
