Website R1Soft Continuous Data Protection Product Overview

R1Soft Continuous Data Protection is a near continuous backup application for Windows and Linux computers, developed by R1Soft. The software provides user scheduled near continuous disk-based online backups for one or more Windows or Linux servers. Each time a user scheduled backup is performed, Delta encoding deltas are transmitted to a backup repository effectively creating a virtual Disk image. Continuous Data Protection can restore previously captured disk images to another disk effectively replicating the structure and contents to a new disk. Individual files inside of a disk image can be restored to their original location or an alternate computer.

Operation

The first time the R1Soft Continuous Data Protection application is used on a new backup target computer it creates a replica of all data and structure on disk to a disk-based backup repository. After this initial replica the application uses a volume filter device driver to track block level deltas between scheduled synchronizations. The next scheduled backup operation involves creating a point in time snapshot and reading the deltas as tracked by the volume filter device driver. Synchronizations can be scheduled as frequently as every 15 minutes for an entire server.[3] The application is known for its simple web based interface.[4] Microsoft Volume Shadow Copy Service is used on Windows to take a point in time snapshot. On Linux a proprietary Linux kernel module is used.

Structure

R1Soft Continuous Data Protection is designed to move backup data over a TCP/IP network and store it on disk using at least two servers:

CDP Agent
a daemon backup agent that is required in order to make backups of a computer or restore files to it. The agent is installed on Windows or Linux computers and listens for backup or restore requests from the CDP Server.
CDP Server
a daemon that initiates backup requests, stores backup data on disk, and provides a web-based user interface

Limitations

R1Soft CDP Enterprise Edition 3.0 can only store up to 64 TBs of backup data per protected disk or volume.[6]
