All servers are backed up on a rotating basis, there is a nightly, weekly, and monthly backup. Routinely copies of these backups are moved off of the server they reside on to provide a recovery point in the event of a server hardware failure. These regular account backups have been used by PES support personnel in the past to retrieve a clients website data in the event they have accidentally deleted content from their account.
However, we, as a rule, do not guarantee the integrity or safety of data stored on client accounts. It is the clients responsibility to maintain backups of all data stored in their account. (Web pages, code, databases, etc)
Backups can be packaged up/downloaded by the client at any time from within the Client Control Panel.
