1. A partial replication snapshot method, comprising:
- receiving at a replication destination a first snapshot at a first time from a data object replication source;
partially receiving at the replication destination a set of data objects from the replication source that have been modified during a time period between the first time and a subsequent second time;
generating a second snapshot at the second time at the replication destination by using the partially received set of data objects; and
mounting an application onto the second snapshot at the replication destination prior to fully receiving the set of data objects from the replication source.

Abstract
A partial replication step shot method. The method includes receiving a first snapshot at a first time from a replication source and receiving a set of data objects from the replication source that have been modified during a time period between the first time and a subsequent second time. A second snapshot is generated at the second time on the replication source by using the set of data objects. An application is mounted onto the second snapshot prior to the set of data objects being received to completion.

8. A computer readable storage medium having stored thereon, computer executable instructions that, if executed by a computer system cause the computer system to perform a method comprising:
-
receiving at a replication destination a first snapshot at a first time from a replication source; partially receiving at the replication destination a set of data objects from the replication source that have been modified during a time period between the first time and a subsequent second time; generating a second snapshot at the second time at the replication destination by using the partially received set of data objects; and mounting an application onto the second snapshot at the replication destination prior to fully receiving the set of data objects from the replication source. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A volume replication system, comprising:
-
a computer system having a processor coupled to a computer readable storage media and executing computer readable code which causes the computer system to implement a checkpoint manager module, wherein the checkpoint manager module; receives at a replication destination a first snapshot at a first time from a replication source; partially receives at the replication destination a set of data objects from the replication source that have been modified during a time period between the first time and a subsequent second time; generates a second snapshot at the second time at the replication destination by using the partially received set of data objects; and allows an application to use the second snapshot at the replication destination prior to fully receiving the set of data objects from the replication source. - View Dependent Claims (16, 17, 18, 19, 20)
