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.

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. |

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

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 ".";
