If you're using FreeBSD or Linux as your DB server, you could take a
filesystem snapshot, and then rsync the .fdb file to your other host,
without stopping your DB.



Alternatively, you could have a logging table for each table with a
timestamp, and simply query these logs from the last timestamp onwards, so
you can replicate your DB record by record.



Most replication systems work in a similar way, either by logging, or
registering for events, and hopping in and querying to see what's changed,
and there are quite a few to choose from for Firebird.

Hello,

I have not used the tools you refer to. If you are pushing the
database offsite every 15 minutes, I would hope your database is small
or the tools contain can detect deltas within files.

Perhaps nbackup would be of interest to you if you use Firebird 2. It
can do hot incremental backups quite quickly.
