Thanks very much, Mike, for the additional great comments. I hope I have
incorporated them satisfactorily. I'm attaching DERBY-6399-3.diff and
DERBY-6399-3.zip (the only changes are to the cadminhubbkup01 topic).
Please let me know if more fixes are needed.

> The Derby Server and Administration Guide could clarify better that a backup
> created using the SYSCS_UTIL.SYSCS_BACKUP_DATABASE is effectively a copy
> (with the caveats regarding non-logged data).
> But when using the
> SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE the resulting
> backed up directory is *not* a full copy of the database, and connecting to
> it directly could be missing data, and possibly invalidate the backup.
> Also, it might be helpful to add an example to the rollforwardrecovery page
> that is more of a scenario, whereby first the old, perhaps corrupted
> database, gets renamed, and then a new one is created in its place, but based
> on the backup and using the logDevice text, maybe something like:
> Should a problem have developed with a database, the best approach is to
> shutdown the original database, rename the original database directory, use
> the rollForwardRecovery with the logDevice attribute, for instance in a linux
> shell, if the database wombat was previously backed up to directory /backups:
> mv /databases/wombat /databases/brokenwombat
> cd /databases
> then do the following in ij:
> connect
> 'jdbc:derby:wombat;rollForwardRecoveryFrom=/backups/wombat;logDevice=/databases/brokenwombat';
