Abstract

A system comprising a processor and a memory storing instructions that, when executed, cause the system to identify a plurality of dump units associated with a translation table in a storage device, determine a plurality of snapshot markers associated with the plurality of dump units, calculate a first value of a first snapshot marker from the plurality of snapshot markers in the storage device, identify a second snapshot marker from an additional source, the second snapshot marker having a second value satisfying the first value, retrieve a dump unit associated with the second snapshot marker from the additional source, and reconstruct the translation table using the dump unit.
