[Evolution] Restore of Evolution 3.10.4

[pequod <pequod isp com>]

Linux Mint 17.2
Cinnamon 2.6
Evolution 3.10.4

Called up Evolution, missing Contacts, Calendar, Tasks, and Memos.
Tried Restore from my latest saved backup.
The only success was Contacts. The others are vacant which means I'm 
missing significant data.
Tried Restore again using the backup immediately previous to the latest.
No change.

Aside from being miffed, I'm also thinking that I'm missing something 
here (operator error, etc.).
I'm not understanding.

Suggestions appreciated.
