I’m returned from my 1-week vacation today and want to say – I’ve never been so productive as I was there Blue ocean, hot sun and white sand really helped me to finish my work on the first release of one really awesome project.
Today I’m proud to announce our first public release of the Data Recovery Toolkit for InnoDB – set of tools for checking InnoDB tablespaces and recovering data from damaged tablespaces or from dropped/truncated InnoDB tables.
This release already has a pretty decent set of features:
- Supports both REDUNDANT (pre mysql 5.0) and COMPACT (mysql 5.0+) versions of tablespaces
- Works with single tablespaces and file-per-table tablespaces
- Able to recover data even when processed InnoDB page has been reassigned to another table and/or was partially destroyed
- Supports all MySQL data types except BLOBs, SETs and BITs (will be implemented in next releases)
- Has really great set of data filters to define data ranges (for numbers), field lengths (for variable length fields), character sets (for strings), date periods (for dates), etc.
- Shipped with easy to use tool which could be used to create innodb table definitions based on CREATE TABLE clauses, so you don’t need to write table definitions yourself – you just need to add data filters and get your data back (well, in most of the cases)
- Results are presented in CSV file format which could be used with MySQL’s LOAD DATA function
So, if you intrigued enough and would like to check it out, welcome to Google Code page of the project where you can find latest version of the toolkit code and more links to information resources related to InnoDB data structures and recovery procedures.
And last thing I’d like to mention is that if you’ll need any professional help in data recovery for MySQL (not only InnoDB), do not hesitate and contact us – we’ll do our best to help you to get your data back.
