Provide mnesia_rocksdb:backup/1,2 and restore/1,2 that pair a Mnesia checkpoint (schema and non-RocksDB tables) with RocksDB backup engines for open admin and standalone databases. Restore stages RocksDB into a sibling directory and redirects mountpoints while Mnesia fallback purges the real directory, then relocates the data and optionally restarts. Raise the minimum OTP version to 27.
To run the mnesia test suite, replacing disc_only_copies references with rocksdb_copies: ``` cd $ERL_TOP make release_tests cd release/tests/mnesia_test cp $MNESIA_ROCKSDB/test/mnesia_rocksdb_backend_xform.erl . cp $MNESIA_ROCKSDB/test/Emakefile . ``` You may use github.com/uwiger/parse_trans, and pretty-print the debug_info in the transformed test suite modules using the following alias: ``` alias pp='escript $PARSE_TRANS_ROOT/ebin/parse_trans_pp.beam' ```
