IBM Informix OnLine Database Server Administrator’s Guide

When you initiate Continuous-Backup, OnLine backs up any full logical log
files immediately. Continuous-Backup does not back up the current log
(status

C

).

If you press the Interrupt key while a backup is under way, OnLine finishes
the backup and then returns control to you. If OnLine is waiting for a log file
to fill, the option is ended immediately.

If you are logged in as user informix, you can start the Continuous-Backup
option from within

DB-M

onitor or from the command line. If you are logged

in as root, you must use the command-line option.

You can start continuous logging in online mode.

From within

DB-M

onitor, select the Logical-Logs menu, Continuous-Backup

option to start continuous logging.

When you do so,

DB-M

onitor executes the tbtape process and an interactive

dialogue is begun on the

DB-M

onitor screen. You are prompted to mount a

tape on the logical log backup tape device. You are also prompted if an
additional tape is needed.

Execute tbtape -c from the command line to start continuous logging.

Do not start continuous logging from the command line in background mode
(that is, using the

UNIX

operator on the command line). The tbtape process

initiates an interactive dialogue, prompting for new tapes if necessary. It is
easy to miss the prompts and delay the backup process if it is executed in
background mode.

For further information about the tbtape utility, refer to

.

To end the Continuous-Backup option, press the Interrupt key at the terminal
that is dedicated to the backup.
