What they found is definitely not encouraging.
This is what Google could do on your documents.
- Google can discontinue the service at any time with no notice, and you may lose your files with no notice.
- Google retains the right to filter or remove content.
- Google can put ads wherever they want, with no notice to you.
- Deleted documents may remain on Google’s servers for up to three weeks.
- Adobe can discontinue providing the service at any time, with no notice.
- You retain ownership of your files, but “By maintaining your
Content on the Services, you grant to Adobe a non-exclusive, worldwide, perpetual,
royalty-free and fully paid license under all intellectual property rights to copy, distribute,
transmit, publicly display, publicly perform, transmit, and reformat your Content solely
to deliver the Services to you.”
- Adobe may read your content for legal or technical reasons.
And, finally, Zoho:
- “Unless specifically permitted by you, your use of the Services does not grant AdventNet the license to use, reproduce, adapt, modify, publish or distribute the content created by you or stored in your Account for AdventNet’s commercial, marketing or any similar purpose.”
- Zoho can block or remove content that infringes copyright or violates laws.
- Zoho can terminate your account at any time for any reason.
- Files may remain on their servers after deletion for an unspecified length of time.
I think the worst aspect underlined in these bullets, is that no one (neither Google nor Adobe nor Zoho) is assuring you for the backups and stability for the service they provide. They can "discontinue the service with no notice" and "you may lose your files".
So... you put your things in the cloud for ubiquitous computing and access and you trust three of the biggest providers out there to backup your files periodically but they don't assure you anything.
Well, I think this is the deal for "el-cheapo" (read: free) solutions but I don't really think I'm going to put my sensitive & important files on a provider's hands unless it shows me a strong and public backup policy and fair Terms of Service.
As for now, I'll keep up with my rsync backup strategy (NAS + USB disk), fingers crossed.
