Recover missing schema

[Thiago Moreno Thimor]

Hi everyone,

I do not know how, but all innodb schemes disappeared from mysql. The schemas folder is also not in the data directory. It was only the ibdata, the ib_logfile0, ib_logfile1 and mysql and test folders.

I do not know if someone or some virus deleted. I want to know whether we can recover, because unfortunately have no backup.

I tried a tutorial that restore an old backup and then overwrites the file ibtada ib_logfiles and then start mysql with innodb_force_recovery = 6 parameter.

The database starts, but the INFORMATION_SCHEMA.TABLES table does not get the reference of the schemes that are gone.

Is there any way to recover the database without the backup?

Thanks
