garbage collection may easily take this time.
Secondly, if these remote stations are online - you could replicate your
data. this would mean that you only ever insert new records and never insert
the whole year's data every night. By end of December your inserts/deletes
will be very large. With replication, your cycle would be real time and very
low bandwodth in comparison.
Check IBPhoenix.com for several replication tools.
If this doesn't suit, then there are several "copy" systems which may offer
