recovery point set

Contains a base recovery point (an exact copy of an entire hard drive stored in a compressed file), plus one or more incremental recovery points (an exact copy of changes made since the base recovery point was created). When you restore a drive using a recovery point set, the base recovery point and all the incremental recovery points are used for the restore. All the files in a recovery point set must be in the same directory. If any file is missing, the backup is invalid and you will not be able to restore your data.
