"Hot backup" support
Up one level
Backup is critical to security and reliability, and Plone allows you to back up without any downtime to the system.
A hot backup — also called a dynamic backup — is a backup performed on data even though it is actively accessible to users and may currently be in a state of being updated.
Plone supports hot backups, and does not require any downtime for the system — which is convenient when you have people around the world and in other time zones using your system.
