We have now standardised on Akeeba Backup on all our sites.
Taking backup of each site is now done at a simple click of a button in the Joomla backend, or can alternatively be triggered from the frontend.
One of the major advantages with Akeeba over other solutions is that this backup includes the whole database, and aaso includes an extremely easy to use recovery process which makes a recovery a simple task as well.
We therefore believe we have now moved to the best Joomla backup solution available at the moment which also have lead to them achieving the "editor's pick" status on the Joomla extensions directory.
