Hey folks, Sorry if this info is covered elsewhere -- I searched but was unable to find a description of what I wanted. Roughly how much storage is used by snapshots? Is it really just marking the version of certain objects, such that multiple snapshots of the same (unchanged) object consume essentially no new space? Correspondingly, once that object is finally modified, it is copied and the snapshots still point to the original (old) copy? Is this done by using hardlinks or some other method? Just wanted the 10,000 foot view explanation. =) Thanks, - Travis -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
