MBR(MicroBR)

This is a project or small toy to learn TiDB BackupRestore(BR).

1. Added functions: Now, you could use mbr to parse what the file named backupmeta and generated by TiDB BR stored,like below:

mbr parse backupmeta -s /path/to/backupmeta

2. planed functions: And, I am tring to add more functions, like basic backup function of TiDB BR , in the long learning journey.
   but,it haven't finfished yet...

mbr backup table ...

3. How to use: If you just wanna ues mbr to parse backupmeta file, you could use it like :

4. How to build: If you wanna participate in this project or explor more details,you can operate like :

make
./bin/mbr --help
