incremental recovery point
Recovery point set consisting of a base recovery point (.v2i) and incremental recovery points (.iv2i). Incremental recovery points contain a snapshot of the sectors that have changed on a drive since the base recovery point or the last incremental was taken. Incremental recovery points are faster to create and require less drive space than full recovery points, so they are useful if you want to back up your drive more often without using a lot of time or drive space. Incremental recovery points can also be consolidated. When you restore a drive (or files and folders) to a point in time, the base recovery point and the incrementals up to that point in time are used for the restore. For example, if you took a base recovery point on Friday night and an incremental recovery point on Wednesday morning, later you could restore files, folders, or an entire drive from the base and incrementals. To restore the recovery point, the base recovery point and all the incrementals in the recovery point set must be in the same directory and should not be deleted.
