We have a customer running our older 4D v12-based product. They recently started using the backup product named in the title.
It looks like a pretty low-level backup. I've also read that it is volume shadow copy compatible. It works on the whole volume - can't be set to ignore folders. Does anyone have any experience with this? https://www.r1soft.com/server-backup-manager R1Soft CDP Technology: Technical Overview R1Soft CDP provides user-scheduled, near continuous disk-based online backups for one or more Windows or Linux servers. The most efficient method for computing deltas is the near-continuous or CDP method. The near-continuous method works by using a Disk Volume Device Driver. The device driver is situated between the file system (e.g. NTFS) and the Disk Volume (e.g. Logical Disk Volume 1). By locating a device driver between the file system and raw Disk Volume, the application is able to identify changed Disk Blocks in real-time without any performance impact. In Windows, this kind of Device Driver is called an Upper Volume Filter Driver. With the near-continuous method of delta computation, a fixed length block size is used that usually corresponds to the file system block size. Typically this fixed block size is 4 KB but can vary in different environments or implementations. As writes to the Disk are observed, the block number that was changed is recorded in a specialized in-memory data structure. The R1Soft technology is built to serve the web hosting market, in which providers often work with very large datasets, lots of automation and minimal manpower – and CDP is able to keep up with the rate of change occurring at these organizations. It’s fast and efficient, with minimal server impact.''
