Some databases allow to write a transaction log to a different drive
so that if the drive containing the database crashes, a backup can be
restored and all transactions since the backup can be recovered using
the transaction log.

Is it true that Firebird does not support a transaction log? If it
does support it, how to enable it?

If there is no such thing as a transaction log, is there any other way
to cope with the problem (DB destroyed, backup does not contain all
transactions)?
