Depending on the cloud
Continuing the theme of over reliance on technology, owners of the T-Mobile Sidekick smart cell phone got a rude lesson this week. The Sidekick stores its data “safely” in a huge storage system loosely termed “the cloud” – meaning some huge mass of data storage on the internet out there “somewhere” storing your data, but you don’t need to trouble yourself with the details. You’re safe. (think Gmail’s “2GB of storage for every user” for another example of storing data in “the cloud”)
As those of you with large disks have learned, the more stuff you have, the harder and less practical it is to back it all up – especially if you are backing it up to another computer over the internet. The remote backup/recovery services you hear advertised can take as much as a month to complete the first backup of your computer if you have a lot of stuff, even on a good DSL connection. A typical 156kb upstream ADSL connection can transfer about 1 GB of data per day.
So the cloud must be failsafe on its own. Disk must be in RAID arrays that cannot fail and lose data. The idea of ever backing up the entire cloud to one central place is not practical, especially if the data has to be up 24/7 for constant updating. Portions of the cloud must back up each other, and some centrally run control system keeps track of what data is where and what other part of the cloud is its backup.
So the early rumors are the Sidekick server(s) were given a software upgrade, and the upgrade failed and wiped out every server. The result was a catastrophic loss of all data with basically no hope of recovering any of it. There is no backup, because it isn’t possible or practical to do it.

Microsoft has announced they have been able to restore most of the lost data by a time-consuming process that required working carefully to not endanger the integrity of the data… wouldn’t want Paris Hilton’s private pictures attached to the wrong account
