point in time copy
A fully usable copy of a defined collection of data that contains an image of the data as it appeared at a single instant in time.
A point in time copy is considered to have logically occurred at that point in time, but implementations may perform part or all of the copy at other times (e.g., via database log replay or rollback) as long as the result is a consistent copy of the data as it appeared at that point in time.
See snapshot, copy on write, and pointer remapping.
