I have invested years in other online GTD and Project apps/sites only to have them announce they are no longer able to continue the service and no means of exporting years of data that have been stored on their servers.

I am requesting a data backup and restore feature so that no matter what happens to Doit in the future I can be confident in investing my data to this service.

Also I would be interested to know if there are any plans in the future to offer private hosting of Doit, for the same reason as above.
