newsInitAutoBack
WARNING: This utility should be used only by experts or as instructed by Grass Valley
personnel, due to required considerations of system load, system drive space, network
load, and necessary familiarity with the Windows at command and Task Scheduler.
This command schedules a system event which will automatically back up the News
database every Monday at 3 am. The event in turn dispatches the vbrAutoBack batch
file, which affects these files in the \Program Files\Grass Valley\Aurora\DB
Maintenance\ directory:
Most recent backup
newsAutoBack.dat
Previous backup
newsAutoBack.old.dat
Most recent backup log
vNewsBackUpDb.log
Previous backup log
vNewsBackUpDb.old.log
As each successive auto-backup occurs, the previous backup is shifted onto the old
images. After you have run newsInitAutoBack, use the at command or (on Windows
2000) the Task Scheduler to reschedule the event to suit your facility. Alternatively,
without running newsInitAutoBack at all, you can directly schedule an event to dispatch
vbrAutoBack.
Before you use this utility, consider these cautions:
•
The DNP and DSM systems are highly tuned for load. The backups must occur
only at times when the systems are quiescent. Disregarding this caveat may cause
erratic performance or system-wide failure.
•
The backup files, particularly on a DSM, can become quite large and thus
deleteriously affect system performance. If your databases are large, you should
plan to move the backup files off the system as part of the backup process.
•
The DNP systems require very high Ethernet performance, particularly for shared
storage. If your backup strategy involves network transfers of the backups, these
systems must not be playing or recording any clips
•
The newsInitAutoBack command does not check for overlapping backup events.
Be sure to run it only once and inspect its task listing for collisions.
