Darrel May (Contrib)
Version
Description
This contrib uses dar (http://dar.linux.free.fr) to create a feature rich backup system for smeserver 7.x. It adds a server-manager panel (Backup > Disk ARchive) to define, schedule and launch server backups and restores, including full disaster recovery, to and from network shares or an attached local disk. The destination network share can be any accessible network mapped drive. Another server, pc workstation or network attached hard drive. The destination local disk can be any mountable hard disk. IDE/SCSI/SATA/USB. In addition an unlimited number of custom backups may be scheduled.
Installation
To install this contribs issue the following command on the SME Server shell:
yum install smeserver-dar2 --enablerepo=smecontribs --enablerepo=smeupdates-testing
Usage
The contrib adds a server-manager panel labeled 'Backup > Disk ARchive'. All backup and restore operations may be performed using this panel. Usage instructions are detailed in the panel text.
Additional information
The dar utility is available for a number of platforms, including Windows. The Windows Version is command-line only, with no graphical view of files for restoring. A graphical interface (kdar) is available for Linux platforms.
