HP EVA Options. Snapshots initially consume storage space only to store
pointers to the data in the source filesystem, growing in size when source
filesystem data is changed. Snapshots can be fully-allocated (the
maximum amount of storage space is reserved at creation time), or
demand-allocated (the minimum amount of storage space is reserved at
creation time, allocating more as necessary). Snapshots are intended to be
temporary.
A snapclone is similar to a snapshot, except that it completely copies the
source filesystem data at a particular point in time.
