[Lubuntu] Recommended online backup services (or those to avoid)?

[John Hupp]

I see that none of these are installed by default in Quantal:
	Deja Dup
	Ubuntu One
	Duplicity

In fact, a Synaptic search on "backup" doesn't show that any backup 
package is installed.

A little searching indicates that there have been problems installing or 
using Deja Dup + Ubuntu One on Lubuntu, though there are not a great 
many results.

Have any of you had good (or bad) experiences with 
installing/using/restoring from various online backup services?

(And I'm specifically interested in backup-oriented services, though 
I'll broaden the question to include sync services.)
