Abstract
A method, apparatus, and system of a sequencing technique to account for a clock error in a storage area network are disclosed. In one embodiment, a system of a backup server includes a processing module to examine a data timestamped with a sequence of characters denoting a time according to a clock source, an analysis module to determine that the data has been timestamped at an earlier time than an other data previously received, a substitution module to provide the data an incremental sequence number placed with the data using an algorithm until a new data is received that includes a future timestamp with a later timestamp than the timestamp of the other data, and a storage module to store the data.
