If you administer any Ensim servers then you are probably familiar with the constant problems the backup feature has had. Since version 3.5 they have promised to fix this. Well, at the time of this writing, the latest still has not addressed this issue.
This script will backup all of your Ensim sites and Appliance settings and either save them to a directory, or FTP them to a server of your choice, or both. Email notification is also built in.
