Abstract
A plurality of data units with associated timestamps is stored in a time based file system, wherein a timestamp corresponds to a time indicated by a system clock. A time indicated by the system clock is changed while the plurality of data units is being stored. A plurality of epochs is stored in a data structure, wherein an epoch is a period of time between a starting and an ending timestamp selected from the timestamps, and wherein successive epochs have overlapping time periods. The time based file system is reverted to an earlier point in time based on the plurality of epochs stored in the data structure.
