To set the automatic OpenLNS CT drawing save interval, follow these steps:
1. In the OpenLNS CT drawing, click Add-ins, point to OpenLNS CT, and then select OpenLNS
CT Options. The Network Properties dialog box opens.
2. Select Backup/Restore from the Options Category list.
3. In the Drawing Save field under the Auto Save Interval box, enter the desired number of minutes
between the automatic saves in the network properties. The default value is 60, which means that
the OpenLNS CT drawing is saved every hour by default.
4. In the Database Backup field under the Auto Save Interval box, enter the desired number of
minutes between the automatic database back ups. The default value is 0, which means that
automatic backups are disabled by default.
Once you set a database backup interval, OpenLNS CT will make the automatic hot backups on
the specified interval as long as changes have been made to the network database since the
previous backup, the changes were made using OpenLNS CT or reported by an OpenLNS event,
and you are using OpenLNS CT on a local client. The hot backup will be stored in the
DbBackup<dd>\<network name> folder, where <dd> is the number in the sequence of hot
backups made for that network (for example, the third hot backup made for a network named
“Building” would be stored in the DbBackup03 \Building folder, provided that the maximum
number of hot backups is set to 3 or more).
5. You can set the maximum number of hot backups that are saved for all OpenLNS CT networks
(includes hot backups created automatically and manually). By default, OpenLNS CT will save
five hot backups of a given network database before deleting older hot backups to create new
ones. To change the maximum number of hot backups, enter the desired maximum in the Max
Number of OpenLNS Hot Backups box.
6. You can also set a periodic backup interval, in which OpenLNS CT creates a standard OpenLNS
CT backup of the network drawing and database. When you close an OpenLNS CT drawing and
the periodic backup interval has elapsed, OpenLNS CT automatically creates a network backup or
prompt you as to whether you want to create a backup (you can select whether you want to be
prompted to create the backup in the Periodic Backup Options box. If you create the network
