Today we upgraded all customer portals to the latest version of JCE - Joomla Content Editor - which is our preferred editor on Joomla! CMS.
At the same time we also upgraded Akeeba Backup to the latest version and of course finished with a complete backup of each portal. We maintain a number of backups online in addition to offsite backups of each portal on our inhouse servers for added security. This of both files and database for each portal.
In that way we guarantee that we can restore a portal within a minimum amount of time should so be required.
