rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted.


Nota clasica.png rdiff-backup from Debian throws a warning due to a deprecated method [os.popen2 is deprecated], which can be hidden following the steps at How to shut up Python deprecation warnings.


Nota clasica.png If you need to backup to CIFS (SMB, Samba) or Mac's HFS, please take a look at rdiff-backup FAQ.

Local backup to USB disk with rdiff-backup

USB disk mount point can be defined in /etc/fstab as:

Be sure to have the last JBoss startup script, otherwise use this piece of code to ensure that JBoss is stopped before backuping the files: 

while [ "$(ps -ef | grep java | grep jboss | wc -l)" -gt "0" ]; do
  sleep 5; echo ".";
done
