Continuous Data Protection

RollBack Rx Server Edition is based on a revolutionary new technology that ensures that you can quickly recover from any known virus, vicious hack, software failures, unintentional user errors, and other software corruptions. RollBack Rx Server’s up-to-the-minute backups allow you to completely prevent data loss, downtime, and service disruptions.

A Zero Data Loss Approach

We understand that scheduling backup times to occur during “off hours” isn’t possible if your server data must be available around-the-clock, 24 hours a day, seven days a week, 365 days a year. Setting aside any noticeable interval of time during which backups are created or updated is again not reasonable. Even still, any data changes made between these discrete scheduled backups are vulnerable, unprotected, and susceptible to being irretrievably lost. In short, traditional backup is inadequate to the task of backing-up server-based applications in which data is highly dynamic and often mission critical. Your critical data is at risk every day. What’s required is a means of backing-up that has to be performed continuously while the system is in use even while the server data always remains available.

Fortunately, Horizon DataSys has developed an innovative new approach to server backup that can create continuous backups and run invisibly in the background. This is the emerging new strategy for data protection based on Horizon DataSys’ own proprietary sector-mapping technology. We’ve radically shrunk backup times; each snapshot can be taken in about a second and can be set to automatically occur seamlessly in the background. Sector-mapping provides a fast, transparent data protection method that has a miniscule footprint in terms of resources use, harddisk space capacity required, and CPU usage.

Real-Time Data Backup

RollBack Rx Server leverages your existing backup infrastructure and doesn’t require any additional hardware or specially trained IT staff. Since RollBack Rx Server is a software solution that’s resident on the server, it also eliminates the need for any additional network bandwidth and load requirements. Snapshots can be set to occur as frequently as every minute. This enables RollBack Rx Server to capture data changes in real-time as they occur. It can even capture any files that are open and being edited the moment the snapshot is taken.

RollBack Rx Server can easily roll back to any of these previous point-in-time, or snapshots. It also allows for the immediate restoration of any amount of data, from a single file, folder, drive, partition, harddisk, on up to a complete bare-metal rebuild of all the server arrays. This enables administrators to easily restore any version of any file, for any user, at any time. So instead of a complete system restoration you can do a more refined, granular recovery. You can also do a complete rebuild back to a stable system state snapshot and then drag-and-drop more recent versions of specific files and folders. Horizon DataSys’ sector-mapping technology puts at your fingertips the fastest, easiest restoration of the most recent changes after a corruption or loss without any data loss.

There’s also built into RollBack Rx a way of recovering your current system state by creating new snapshots in a pre-Windows basic I/O interface (also called the RollBack Rx sub-console or mini-OS). This allows for a failsafe method of recovery in case you experience an OS corruption.

Conventional Backup Solutions

Conventional backup solutions use imaging technology which take a lot longer to create backup images. Backing up as little as a few hundred gigabytes can take upwards of an hour and this image is going to be about the size of the original data. Compressing this data will only marginally reduce the extensive harddisk storage space that the image requires. RollBack Rx’s sector-mapping technology allows it to replicate gigabytes and even terabytes of data in seconds and each new snapshot is going to be in the neighborhood of about 1% of your harddisk space.

Backing up to the cloud can take up an exceedingly large portion of your total bandwidth. Many cloud-based backup systems attempt to reduce the total volume of data sent during high-traffic times. High-traffic times are just the moment at which a dynamic system’s backup requirements are the highest but cloud backup methods leave you vulnerable to data loss because backup transfers are delayed or reduced.

In short, most conventional solutions have extensive storage and cost requirements and significantly impact network performance. RollBack Rx doesn’t have any of these network traffic, storage capacity, and servicing downtime requirements. All these static point-in-time recovery methods aren’t practical for protecting dynamic systems. Only RollBack Rx offers the instant backup and recovery times required for continuous real-time protection. These dramatically faster recovery times enable you to schedule backups to occur as often as every minute and recover the latest system data up-to-the-second in case of a system failure.

Continuous Data Protection (CDP)

Continuous data protection (CDP), also called continuous backup or real-time enterprise backup, refers to backup of computing data by automatically saving all version made to the data, essentially capturing everything that the user saves. Continuous Data Protection allows the user or administrator to restore data to any point in time.

Most successful Continuous Data Protection (CDP) applications run as a service that captures changes to data to a specific storage location. There are various technologies and techniques for capturing the changes i-each serving different needs.

The most successful CDP-based solutions can provide fine granularities of restorable objects ranging from crash-consistent images to logical objects such as files, mail boxes, messages, and database files and logs. Sector mapping technology has recently revolutionized how continuous data protection should be performed.

Traditional backups only restore data from the time the backup was made. Continuous data protection has no backup schedules. Continuous data protection is different from traditional backup in that you don’t have to specify the point in time to recover from until ready to restore. When data is written to hard disk, it is also asynchronously written to a sector map and then also a second location, usually another hard drive over the network. This introduces some overhead to disk-write operations but eliminates the need for scheduled backups.

Continuous data protection (CDP), also called continuous backup, is a storage system in which all the data in an enterprise is backed up whenever any change is made. In effect, CDP creates an electronic journal of complete storage snapshots, one storage snapshot for every instant in time that data modification occurs.

A major advantage of CDP is the fact that it preserves a record of every transaction that takes place in the enterprise. In addition, if the system becomes infected with a virus or Trojan, or if a file becomes mutilated or corrupted and the problem is not discovered until some time later, it is always possible to recover the most recent clean copy of the affected file. A CDP system with disk storage offers data recovery in a matter of seconds — much less time than is the case with tape backups or archives. Installation of CDP hardware and programming is straightforward and simple and does not put existing data at risk.
