Good plan :-)

Could you clarify how you deleted data from the database? Did you use the API,
or directly query the RDBMS?

Do you have the zebraqueue daemon running?

Do you have the zebraqueue daemon running?

Hmm ... that's very strange ... which make target did you use? standard, dev?

i think we need to figure out why your zebra directories are disappearing ...

The MARC data is stored as a blob in biblioitems, so you could just mysqldump
that table ... there are also some utilities in the interface in Tools
-> Export Bibliographic and Holdings Data; as well as some command
line tools that do the same thing in misc/
directory.

So ... we need to figure out why your zebra configuration isn't working well,
could you tell us a bit more about your environment?

Also, I'd suggest we take this discussion to the koha-devel list where
more of the
technical questions tend to get hashed out (I've CCed your question to that
list). Here's the list info:
