Double-Take RecoverNow provides the TimeData continuous data protection feature that records every change made to the source image. With every change recorded on the repository server, recovery can occur from any point within the continuous data protection window specified by the user.
TimeData is installed and runs on the repository server. It keeps track of all changes to the source image. Changes are temporarily stored in the Event cache until they can be processed and stored in the Event log.
The longer TimeData stores all changes, the more disk space is consumed. To reduce disk space usage, you should keep changes for only as long as needed and rely on Double-Take RecoverNow snapshots for older point-in-time-recovery. For example, retain the last seven days of all changes using TimeData continuous data protection and rely on Double-Take RecoverNow snapshots for older points in time.
