Simple answer is don't ignore it, here is how I have mine setup.
There are only 2 Shadow Protect Application Event ID's that are used for backup jobs;
- 1121 for Errors including Failed backup jobs
- 1120 for informational events and Successful backup jobs
Note that I split my eventlog monitor sets up so that I can make them trigger unique fake executable files that run for around 1min and gets monitored by a matching Process Monitoring sets. This allows me to split my alerts from the Event Alarm category and have it under a custom category called Backups.
First create your catch all monitor set using the "ShadowProtectSvc" event Source and configure this to use "Error, Information and Warning" event Types. With the catch all you only want to generate Alerts so you don't get spammed by duplicate emails. It is mainly used to discover new event ID's not published by the product vender and is less important.
Next you may or may not want a Successful Backup Job monitor set, I create it so that I can report on successful backup jobs but don't make it generate any alarms. To do this us the "ShadowProtectSvc" event Source, 1120 event ID, the "Information" event Type and a Description of "*completed*".
Now for the Error events. There are two Descriptions that I have noted that are commonly generated however I make a catch all "Failed Backup Job" Monitor set using the "ShadowProtectSvc" event Source, 1121 event ID and configure this to use "Error" event Type.
The first of the known Error events are the "Cannot find the file specified" which is generated if you are using incremental backup jobs and the previous backup file could not be found. The event description for this one is "*Fatal I/O error * The system cannot find the file specified*".
The Second known Error event is for Disk space whit the event description of " *There is not enough space on the disk* "
All in all these monitor sets have worked very well and I'm considering not to waste my time and the company's money on the Shadow Protect module at this point in time. I still want to evaluate this module and make a pro's and con list to make a non-biased decision when I have some time.
