Hello, Tanno!

>OK in the log file is extra information
>(partner index description not found (175))

This error cannot be fixed via backup/restore, because it related with
missed system records in index info.
Usually we can fix such error with pumping all data from corrupted database
to the new empty one created from metadata.

The best tool for pumping is IBDataPump.

Sincerely yours,
