An Undo Button For Your Data
Threats to data abound in today’s electronic world, ransom-ware high among them. Whatever the cause of the damage was, the modification to the data was undesirable and needs to be undone. Continuous Data Protection (CDP) delivers one-second granularity on roll-backs and provides the best Recovery Point Objective (RPO) and Recovery Time Objective (RTO) of any data protection solution.
CDP records every write I/O (or change), with a corresponding time-stamp, that occurs against a protected volume. With CDP, a roll-back volume can be created representing any point-in-time just before the undesired event occurred. The roll-back volume is then mapped to the original application server or a different one.
As data is written to the protected production volume, a copy of each write I/O is copied to the designated CDP buffer pool. A roll-back volume can be created based on the data that resides in the CDP buffer pool at a specified time.
For example, consider a virus causing damage to a volume at 2:41:36 PM; a roll-back volume is created for any point in time prior and served back to the original application server. Also, consider a user deleting a file at 3:15 PM; a roll-back volume is created for 3:00 PM and mapped to a different file server for retrieval, all with no interruption to the production volume.
Similar to snapshot requests, one can generate periodic CDP Roll-back Volumes at known-good restore points by scripting a call to a PowerShell cmdlet each time an application has been quiesced and the caches have been flushed to storage.
