Snapshot

I have snapshot pro installed in Multisite environment.

It is working correctly for one of the sites: sos.myagentgenie.com

But will not create backups for dev.myagencygenie.com or outsideagents.com

I am trying to send the backups to a dropbox account, just different folders.

it is sending to dropbox for one of the snapshots, but not the other 2.

Any ideas why this would be?
