We have a large xsan volume of 28 TB. We want to sync this volume every night to another xsan volume of the same size. In the beginning when the volume was smaller rsync did the job. But now with 28 TB rsync is just to slow so it cannot get the job done in one night.
cvcpSync uses rsync to get a list of all the changes and then use cvcp to actually copy the data. This dramatically improves the speed.
