Hello,
This is not possible through CCA, but you can use CLI and the CUE web gui to do this. There are also 3rd party tools you can use to do the automated backups.
See this post for the more info about backups: https://supportforums.cisco.com/thread/2155698
Here is an example how you would do this in CME:
kron occurrence monthly at 01:23 june 20 recurring
policy-list save-config
!
kron policy-list save-config
cli copy system:/running-config tftp://192.168.1.2/router-confg.txt
In the CUE web GUI under Administration you need to define the backup server. Then you can create a scheduled backup.
You will need FTP and TFTP servers running somewhere to backup the configurations and data to.
Hope this helps.
Thanks,
