You are very likely looking for the Podolia/Podolsk/Podolskaya Gubernia/Region > Russian Gubernia, 1796-1917, in the "Pale" part of Czarist Russia. Today, southwestern Ukraine. Capital: Kamyanets-Podilskij.
Country, regional, and district borders have changed several times since.
I suspect that you will need to locate exact town or village in Podolia.
Most Jewish Records for Podolia Gubernia were held in Kamyanets-Podilskij Archives, which had a severely damaging fire April 10, 2003.
Five major fonds covering the history of Podolia Gubernia from the end of the seventeenth to the twentieth century were damaged in the fire, the cause of which is under investigation.
In addition to those documents that were completely destroyed, many unique historical documents were water-damaged. Over 2 tons of archival material had been evacuated from the destroyed warehouse. About 10,000 items, which were transferred into the refrigerator and frozen at -30C, are progressively being dried.

If anyone knows where to possibly locate Kamenets Podilskij Archives duplicates, if there are any, it would be Mariam Weiner.
