is there a way to programmatically disable backups on jira and confluence?

[jira guy]

I have setup bamboo builds for auto refresh of jira and confluence prod data to staging. They work great with modifying base url, smtp and other stuff. only issue now is a way to disable the backups? these backups are usually configured in UI for scheduled jobs

let me know if anyone did this already. 

I tried this for confluence which didn't work.

update BANDANA set BANDANAVALUE = replace(BANDANAVALUE, ‘<backupDaily>false</backupDaily>’) where BANDANACONTEXT = ‘_GLOBAL’ and BANDANAKEY = ‘<backupDaily>true</backupDaily>’;
