Abstract
The writing of data to a storage system such that change tracking is efficiently performed. If a portion is to be written to the storage system, the system writes a write record indicating that a group of portions (that includes the particular portion) of the storage system is to be written to the storage system. This is represented even though those other portions are not being contemporaneously written to the storage system, and may in fact never be written. The particular portion is then written to the storage system. At some point thereafter, perhaps in the background, a change tracking structure is changed to reflect that the particular portion is written to the storage system, but without reflecting writes of all of the group of portions. The write record may then be invalidated. This reduces latency in systems that track changes with small cost at the time of backup.
