|
// between a given storage and another point of reference
|
|
// (another storage, a version id. or a time stamp). In the
|
|
// first case there is no temporal significance to the differences
|
|
// extracted, i.e., it is the difference in the snapshots at
|
|
// that instant of time. For the second and third cases there
|
|
// is a temporal significance attached to the differences. These
|
|
// also require some form of history to be associated with the
|
|
// storage.
