Description
The configuration backup should be a very small file which changes only on rare circumstances.
Actual implementation will recreate the file each time backup-config command is launched.
- ldap dump (nethserver-directory)
- maildir structure (nethserver-mail-server)
- tdb dump (nethserver-samba)
- acl dump (nethserver-ibays)
- shared folder directory structure (nethserver-ibays)

- Create backup only if files are changed

- Do not backup ibay structure
- Move acl dump and restore to backup-data
- New option
--same-hardware
The algorithm works as follow:
If destination file (backup-config.tar.xz) doesn't exists, just create it excluding all files belonging to a RPM and listed in .exclude files.
After file creation, calculate MD5 sum of all archived files (backup-config.tar.xz-content.md5)and the archive itself (backup-config.tar.xz.md5).
If destination file already exists, check if any file is changed using MD5 signatures. If at least one file is modified, create a new backup
All files are saved inside /var/lib/nethserver/backup directory.
The restore-config command has a new option --same-hardware. If the option is specified, network configuration will be not wiped out at the end of restore. This option is useful when restoring a configuration database on the same hardware.
