TwinDB data recovery toolkit

Supported Failures

 TwinDB Data Recovery Toolkit is a set of tools that operate with MySQL files at low level and allow to recover InnoDB databases after different failure scenarios.
The toolkit is also known as UnDrop for InnoDB, which is more accurate name because the toolkit works with InnoDB tables.
The tool recovers data when backups are not available. It supports recovery from following failures: >> 이 도구는 다음과 같은 데이터베이스 고장으로 인해 잃어버린 데이터를 복구할 수 있습니다.
A table or database was dropped. >> 오삭표 또는 데이터베이스InnoDB table space corruption. >>innodb표 공간 파손Hard disk failure. >> 하드 드라이브 장애File system corruption. >> 파일 시스템 장애Records were deleted from a table. >> 표 기록 삭제 (delete) A table was truncated. >> 테이블이truncateInnoDB files were accidentally deleted. >> 이외 innodb files 삭제A table was dropped and created empty one. ## Installation The source code of the toolkit is hosted on LaunchPad.
