I think the solution is a message queue. It's a system that guarantees
the message (record) is delivered to the other system (database) and
it can give that guarantee because it stores all the messages in it's
own database. So when the remote system is unreachable the message
queue stores all the messages in order and when the remote system
comes back up, the stored messages are resent in order they where
received.

There are a number of free open source message queues, so only issue
is how much time, effort and resources (a second server) do you what
to spend?
