Bonjour Ibrahim
rdiff-backup does not have any built-in encryption. Also based on my
experience rdiff-backup should not be run directly over the internet, it
should be run on a lan (or of course a single machine) and then the
rdiff-backup repository (archive) mirrored over the internet using
rsync. This works very well for maintaining offsite data backup and the
internet transmission is secured with ssh. This approach is used by my
TimeDicer package (http://www.timedicer.co.uk). However this assumes
that both source and destination are secure.
It is possible to wrap rdiff-backup in some encryption e.g. with encfs
or ecryptfs. Another option is to look at project duplicity
http://duplicity.nongnu.org/. Duplicity grew out of rdiff-backup, however:
-rdiff-backup's archives are meant to be as easy to view as possible,
while duplicity's are as hard to view as possible and can be encrypted
with GnuPG
- duplicity saves data in the more conventional full+forward delta
format instead of rdiff-backup's mirror+reverse deltas
- rdiff-backup requires another copy of rdiff-backup on the remote
destination, while duplicity currently supports local file storage,
scp/ssh, ftp, rsync, HSI, WebDAV, Tahoe-LAFS, and Amazon S3
Note: the use of forward delta/diff format by duplicity means that
recovering data from the most recent incremental backup requires a
complete undamaged set of incremental backups from the original full
backup until the most recent date; in order to reduce this dependency
and the associated risk many duplicity users carry out new full backups
every month or so, but this means you lose all your older backups (or if
you retain them and create a parallel new archive you lose most of the
advantage of the delta storage). rdiff-backup, by contrast, stores the
most recent backup 'in the clear' so it is always easy to retrieve (not
even requiring the use of rdiff-backup itself), and the backup
increments apply in reverse order, so most recent backups are inherently
safer and older backups more vulnerable.

Good morning Sir,
I am working on a project which consist to use rdiff-backup to make
backup of data on line.
So looking on internet i don't find anyway if rdiff-backup can make
encryption component
of data send
Reason why i contact you, thank you for yor help.
Cordialement,
