MS Volume Shadow Copy Service is a facility that can be used for many different purposes. One feature of VSS is the ability to take a block level point-in-time snapshot of a disk Volume. VSS guarantees that the file system is consistent when a snapshot is performed.
Most Windows CDP applications (R1Soft is an exception) use MS VSS for shared folders. These applications do not delete the snapshot in step 10 when done and instead must keep the snapshot and perform copy-on-write the entire time until the next backup operation. This is because the method of computing deltas (VSS for shared folders) works by comparing two Volume Shadow Copy snapshots.
R1Soft uses Volume Shadow Copy Service to take cluster level point in time volume snapshots of the running volume/disk.
