Quote from Subbz:
"I plan to support retrieving guide data and recording data from the primary
backend to the slave so the remote slave can schedule programs and add
programming rules, adding support to the db for tracking information so that
I can safely and correctly synchronize recording rule changes in both
directions depending on which is most up to date, and other necessary
tracking info in the DB."
Replication is perfectly valid solution. He might need to putz around
with a newer mysql and use the auto-increment offset magic, but that's
easy enough to do and would alllow both sides do schedule recordings
and have them sync up correctly and the like.
nuvexport + sql files is only one way, not what he asked about.
