Summary: This has been unused since D42069 but kept around for backward compatibility. I think it is unlikely anyone will use a much older version of RocksDB for restore than they use for backup, so I propose removing it. It is also causing recurring confusion, e.g., https://www.facebook.com/groups/rocksdb.dev/permalink/980454015386446/ Ported from https://reviews.facebook.net/D60735 Closes https://github.com/facebook/rocksdb/pull/1529 Differential Revision: D4194199 Pulled By: ajkr fbshipit-source-id: 82f9bf4
