Partial backup question

We have schema that have ‘-’ in it’s name, let’s say foo-bar, but Percona 5.5 server creates corresponding directory foo@002bar in data directory for this schema.

My question how should I refer to this schema if I want to pass it in --databases option of innobackupex script?

I don’t know, but perhaps you can test and post the answer, and then we can update the documentation.
