5 Online Storage Services -- Which is Best for Keeping YOUR Data Safe?

SpiderOak SpiderOak is flexible enough to back
up anything, to share files easily with your friends, and to sync files
between Mac, Windows, and Linux machines. It installs as an actual
application, but it’s Flash-based, so if you use it on two or more
platforms, the experience will be the same.
You can back up as
many computers, external hard drives, and network volumes and servers
to your SpiderOak account as you want. The other services we tested
don’t allow you to back up network volumes, but since SpiderOak sells
storage in 100GB increments, you’re encouraged to back up as much as
possible. You select the files and folders to back up in the Back Up
tab of the SpiderOak app, or you can just click the checkbox for a
preset category, including Dekstop, Documents, Email, Movies, Music,
and Pictures. The preferences let you exclude files and folders by
wildcard (filenames including *.zip, for example) or exclude files
based on their size or age.

The Backup tab lets you select categories (to the left) or specific folders to back up.
Once
files are backed up to your SpiderOak network, they appear in the View
tab, where you can browse the folder structure for each of your
backed-up devices. Select a folder to highlight the Changelog and Merge
buttons. Merge does a one-time merge of all the files in any two
folders on your SpiderOak network. The Download button restores your
selected files to a location you specify in the preferences.
Your
files are encrypted with a combination of 2,048-byte RSA and 256-bit
AES and compressed, so you’re not paying for more storage space than
you need. When you change a file, SpiderOak only saves the changes, so
the data blocks for the parts of your file that didn’t change aren’t
backed up again. And if you have a file on two machines and back up
both to your SpiderOak network, the file will appear in both machines’
View list, even though it’s only stored on SpiderOak’s server once. You
still see all versions of your files under the View tab, and clicking a
file with more than one version displays the date each was updated, so
you can find the one you need.

SpiderOak keeps all versions of your files, in case you want to restore an older one.
Share
sets, which are set up in the Share tab, make chosen files and folders
in your SpiderOak network available to anyone via their Web browser.
You choose a Share ID and Room Key, which are combined into a URL you
give to friends. And the Sync tab lets you set up Sync sets, choosing
two folders in your SpiderOak network that will always stay in sync on
the local machines. We used one Sync set to keep our
~/Documents/Receipts folder synced between our home iMac and work
laptop, or you could sync a local folder to an external hard drive.
SpiderOak
even encrypts your encryption key. The company doesn’t know your
password, although you can set up a hint. SpiderOak employees can never
access your data—and if you forget your password completely, neither
can you.
We loved the Sync feature, as well as the ability to archive files to
the SpiderOak network and delete them off the local machine. If our
only complaint is that the SpiderOak icon stays in your Dock when the
app is running, you know there's not much to complain about.
