Hello list,
I am storing dumps of a database (pg_dump custom format) in a de-duplicating backup server. Each dump is many terabytes in size, so deduplication is very important. And de-duplication itself is based on rolling checksums which is pretty flexible, it can compensate for blocks moving by some offset.
This might be a silly question, but why are you using -Fc to create multi-TB dumps instead of -Fd? If nothing else, the parallelization granted by -Fd will greatly speed up the dumps.
