We are developing a web app and planning to deploy it in a multi-tenant model. However, some of our potential customers are having a great deal of discomfort with the idea of not having the control for their data. With that concern, we are planning to let them host their own database. But we are having a problem on the backup, if the customer is hosting the database, we can't back it up for them.
Is there anyone who had dealt with this kind of situation before? Any suggestions/comments will be appreciated! Thanks!
