Turning Off Parallel Backups
Setting the system variable NSR_MPE_SCHED_SAVES_PARALLELISM_OFF to any
value, including null, turns off any parallelism of server-initiated backups. Backups
that are scheduled to run at the same time as defined in the client resource on the
NetWorker server will run sequentially.
This variable is useful when the host and its I/O are unable to gracefully sustain more
than one volume-set-based save at the same time. Note that parallelism can also be
turned off by setting the "parallelism" attribute of the client resource to "1" (refer to the
Legato NetWorker Administrators Guide).
To turn parallelism of server-initiated backups off, add the following system variable
to the JNSRSTRT file:
!SETVAR NSR_MPE_SCHED_SAVES_PARALLELISM_OFF ""
Note that if you set this variable to "no", parallelism will still be turned off.
You can also set this system variable from the POSIX shell:
$
export NSR_MPE_SCHED_SAVES_PARALLELISM_OFF=""
Specifying a Notification at the Start of an Online Backup
To set the notification system variable to on or off (the default is off), use the following
command:
!SETVAR NSR_MPE_NOTIFY_ON ""
You can also set this system variable from the POSIX shell:
$
export NSR_MPE_NOTIFY_ON=""

Manual for more information on this feature.
Controlling the 7x24 True Online Backup
You can set three different controls for the 7x24 True Online Backup:
The ONLINE=START option allows you to enable active data backups. This
setting is the default.
The ONLINE option allows you to specify ONLINE without START.
The OFF option allows you to turn the ONLINE off.
To control the 7x24 True Online Backup, add one of the following system variables to
the JNSRSTRT file:
!SETVAR NSR_MPE_7X24_ONLINE ”ONLINE=START”
!SETVAR NSR_MPE_7X24_ONLINE ”ONLINE
!SETVAR NSR_MPE_7X24_ONLINE ”OFF”
You can also set these system variables from the POSIX shell:
$ export NSR_MPE_7X24_ONLINE=”ONLINE=START”
$ export NSR_MPE_7X24_ONLINE=”ONLINE
$ export NSR_MPE_7X24_ONLINE=”OFF”
