How does Ubuntu One work?
Solution 1:
Ubuntu One is a synchronization service. It synchronizes every change you make to your file - delete, rename, edit, move etc.
So, if you delete the file from your PC after it gets uploaded to Ubuntu One, your file would be deleted from the Ubuntu One account as well.
What you actually need is to use a Backup/File Storage service. Some of the popular options before you are:
- Déjà Dup along with Ubuntu One - Can I use my Ubuntu One account to backup with Déjà Dup?
- SpiderOak
- CrashPlan
- Wuala
