R1Soft claims near continuinous data protection for MySQL. What is that?
• Continuous data protection (CDP) means that copy of data is saved every time data changes. The purpose of CDP is the ability to restore data to any point in time. ZRM 2.2 provides CDP functionality for MySQL. • Near CDP means that multiple recovery points are created allowing to restore to a point in time that is close to the Recovery Point Objective. • R1 uses proprietary snapshot technology to make multiple snapshots of Linux volumes. • R1 does not take any advantage of MySQL functionality, and it does not allow recovery to a point-in-time (which is the whole purpose of CDP). • R1 snapshots are done without locking of MySQL. It means that recovered database might not be consistent. It is extremely risky to perform any storage level backup of the MySQL database without taking at least a momentary read lock at the database level. • The price starts at $990 for the first MySQL server + $240 for each additional MySQL server. There are no SLAs for support. • Solution is not open and you
