Thank you for all of the suggestions - we are weighing the different
solutions now! We really want a true shadow/mirror so gbak is obviously

or a more flexible (any brand) solution [C-JDBC].

Thanks all!

Hi Ron,

Have you considered using shadowing? Firebird will create shadow
databases (on a different drive on the server for example) and write to
the main and shadow DB simultaneously. It can also be set to
automatically fail over to the shadow if the main DB goes offline.

From your description it sounds like you are more interested in backup
than true mirroring.

The two copies of the DB have to be on the same server but can (and
should) be on different drives.

The Operations Guide Interbase 6 manual (OpGuide.pdf) has all the
