Hi,

That's unfortunate problem. The API requires byte streams, while
os.path.exists requires unicode. The obvious solution is to
encode/decode at either place, but the key problem is which encoding we
should use? Any ideas?

What about moving the line:

source_database = ibase.b(source_database)

from services.backup and services.nbackup to services.add_database_name

In other words leave 'source_database' as a string and only convert it to byte streams in add_database_name.

Werner
