Differential backups with CPS selections
Updated: 28 Jul 2010 | 8 comments

When I select a file to back up in the CPS destination location, it backups the folder but not the file. What is going on?

Never mind - got it. You have to stop the CPS services before backing up the CPS destination location. :)
In the CPS admin guide, it says not to do a regular backup of the CPS Protected Resources node given that it contains a lot of redundant data.
I will use this article http://seer.entsupport.symantec.com/docs/288626.htm to configure pre/post commands for the backup of the CPS destination data. Hopefully tonight it will be nice and quick.
