Sorry for the late response. The backup server was originally located in the LAN (using 10.20.1.75 IP Address) and was working fine. After letting it "bake" for a couple days without issues, the system was relocated offsite. Offsite network is running a 198.x.x.x range.
Had them do the following:
1) Change the IP Address of the Server to 192.168.1.5 (Also set the Subnet and Gateway).
2) Test to ensure Internet Connectivity (worked)
3) Updated the affa job to change the "remoteHostName" to the External IP Address of the Production Server.
4) Ran "affa --check-connection", which provided a successfull result
5) One the Production Server, I deleted the file "/etc/cron.hourly/affa-watchdog-prodbox-10.20.1.75-reminder" (so the file would be recreated by the Backup Server)
This morning, I received the message:
The backup job 'prodbox' scheduled on Mon Sep 20 22:30:09 2010 did not run.
Please check and fix your affa configuration on ddgbackup.ddgbackup.local (192.168.1.5).
A reminder message will be sent at 22:00 hours, if the error continues unchecked.
Remove the file /etc/cron.hourly/affa-watchdog-prodbox-192.168.1.5-reminder to stop receiving reminder messages.
I will have the on-site person run some checks to see if the backup did actually run. However, it would appear that it was able to communicate with the Production Server since it recreated the "reminder" file, which reflects the new IP Address.
Also, I will have them get me the output of "db affa show prodbox".
