Same here. It seems that all the proponents of "cloud computing" seem to gloss over this aspect of the whole thing: your data is not in your hands once in the cloud, period. You're at the mercy of the servers on which it is stored, and if anything happens and there are idiots in charge... boom!
Running your own apps is only a good idea if you are keeping one more backup copy than you would if you were running in the cloud. Think about it.
When Francine Fishpaw loses her data because she didn't back it up, it doesn't make the news. And yet it happens to people like her every day. All the Earl Peterson's, Dawn Davenport's, and Donald and Donna Dasher's of the world who lose their Microsoft Works data go unnoticed.
Agreed. The fact that this is such a notable exception should tell us something.
There are arguments against putting your data in the cloud. But this is not evidence for any of them.
Seriously , though, regardless of whether the data was stored online or at home, screw ups happen. Better to have backups in multiple places, and if I was running a large network, I'd have 2 locations online. One for backups and a separate one for the snapshots/diffs.
I don't know if this is feasible for medium/large companies, but it would be well worth my time for a small business. my2cents
The problem is simple really...
People mistake a high-availability solution as a backup solution.
RAID/Cluster/Cloud != backup.
The problem arises when some software bug deletes the data - your so-called backup is immediately deleted too.
Backups should be taken frequently and the most distinguishing feature of a backup: It is offline storage.

A lot of people say that but's that's not really the case. The more frequently you perform your backups, the more it approaches RAID, especially if you want to be safe and backup all changes. After all, losing a single days' work or even a couple hours of work can still be just as devastating.
Suppose your backup strategy is a simple sync. Well, a frequent backup will also be affected by whatever destroyed your data in the original. Suppose you say you won't delete files. Ok. But your originals can still be destroyed by zeroing out files or by user/app level corruption (intentional or not like a bug). And again, your backup will be affected especially if it's a frequent backup.
I suppose you can mitigate this by having multiple/rotated backup copies or a versioned backup scheme, or snapshots but that adds a large strain on storage costs and space.
