Automatic backups
The VPN Router checks at regular intervals to see whether there are any system
file changes. When system file changes occur, they are written to each of the
backup servers. The VPN Router backs up all of the system files the first time;
thereafter, it backs up only the files that change.
The VPN Router does not begin a backup for at least 5 minutes after rebooting to
allow all resources to start operating. This delay occurs even if you request that a
backup start immediately. Use the Admin > Auto backup window to configure
regular intervals or specific times when your system files are saved to designated
host backup file servers. You can designate up to three backup file servers.
Note: You cannot use this procedure for the VPN Router 1000 due to
the lack of a floppy drive in the unit. Although the VPN Router 600 does
not have a floppy drive, the recovery image is stored in a PROM; you
can invoke it by pressing a switch on the back of the unit.
Note: Any changes made to backup parameters while a backup is in
process do not take effect until the currently running backup is complete.
