Hi
Redhat 5 x86_64
MySQL 5.1.49sp1
using innodb_file_per_table
I recently used zmanda to restore a database that has only innodb tables to a different server.
After the restores was complete, I was unable to start the instance. The log was complaining about ibdata. For example:

InnoDB: you deleted or moved .ibd files?
InnoDB: Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.1/en/innodb-troubleshooting-datadict.html
InnoDB: for how to resolve the issue.
</snip>
Since I was unable to restart the instance, I copied the most important databases to another location as well as the ibdata1 ,ib_logfile0 and ib_logfile1 to another location. The databases I copied contain only Innodb tables.
I deleted everything, but the mysql database, and started the instance as if it was _new_. It is up and running. Obviously all the data that was originally in this instance is gone.
Can I recover those databases that I moved?
Thanks
