What is Continuous Data Protection?


Downtime and data loss create a painful risk for businesses. Data backup is one of the most important tasks facedData Protection within organizations today. The good news is that technology for data protection is easier and more effective than ever before. Continuous backup also called continuous data protection (CDP) or real-time backup refers to backup of data by automatically saving a copy of every change or version made to that data. It allows the user or administrator to restore data to any point in time.

What is the goal of Continuous Data Protection (CDP)?

The goal of CDP is to constantly backup data as the data is created or modified. So, a solution that features CDP such as Asigra Cloud Backup™ eliminates the possibility of losing data between backup sessions because no time goes by between the backup sessions. A backup is always occurring to protect new data. Unlike tape backup, CDP technology does not require the interruption or scheduling of applications to perform backups. It works continuously to backup your critical data to an alternative server so you can immediately recover data from any point in time.

What are the problems that CDP solves?

It’s not uncommon for a user to accidentally delete a file or for a virus to corrupt data files. These actions leave the data unusable, even though the server or other hardware continue to work as expected. CDP enables you to recover a version of your data to a point in time just prior to the accidental deletion or virus corruption. This earlier version of the data can then be restored to the production environment.

What are the benefits of using Asigra CDP:

With Asigra Cloud Backup, CDP allows unlimited granularity since users can have their data recovered from an infinite number of Recovery Point Objectives (RPO). CDP protected files are backed up whenever they are saved to disk by users at the source computers. It also continuously monitors the changes on the specified target files and backs up the changes as soon as they are detected. Asigra CDP is implemented as a backup option and can be applied to file systems and email backup sets to improve recovery Service Level Agreement (SLA) of critical data. Other benefits of Asigra’s software solution include:

  1. Increase SLA compliance. CDP provides the user with the peace of mind that the latest version of critical data has been backed up as soon as they save it on their hard drive and is available to be recovered.
  2. Flexible RPOs. Traditional backups can only restore data to the point at which the backup was taken. With CDP, there are no backup schedules. When protected data is saved to disk, it is also asynchronously written to the central storage repository (DS-System) or to the Cloud. CDP keeps not only the latest saved version of protected data but also keeps track of the previous versions, allowing data recovery from a wider range of time.
  3. Immediate protection of critical data. Once protected data is saved to disk, it is backed up locally (if local storage is available) and is simultaneously sent encrypted over the Wide Area Network (WAN) to be stored offsite in the centralized backup repository. Backup window and Recovery Time Objectives (RTOs) are reduced to zero.
