Both Dropbox and SpiderOak have good security, but I think that SpiderOak wins at being the most secure.
Dropbox transfers all data files over SSL, then stores the files encrypted with 256 bit AES on the servers. Dropbox’s employes are not able to access your files, but however, they can still see the file sizes and the file names.

SpiderOak has taken security to the maximum. All data is encrypted on the client using a combination of 2048 byte RSA and 256 bit AES, and is never decrypted (and can’t be decrypted) until you download the data using the client, and then the client decrypts it. Plus your password is never stored on their servers, and the only thing the SpiderOak employes can see is how much space total you are using on their servers. However they do save the encryption keys on their servers, but the keys are encrypted with 256 bit AES using your password.

Both SpiderOak and Dropbox save backups of modified and deleted files.
With a free account Dropbox will keep backups of your files up to 30 days, or until you permanently delete the file. But you can buy upgrades to get unlimited backups.
Dropbox won’t count deleted files and file backups as disk usage, so you don’t have to worry about the backups taking up extra space on your account.
SpiderOak will keep backups of your files forever. How ever, unlike Dropbox, SpiderOak includes deleted files when counting up account space usage.
Both Dropbox and SpiderOak have a secure online way to get your files using their websites. (Both SSL encrypted)
Using SpiderOak’s website, you can download files, see your list of backed up devices, and edit most of your account info (except changing your password, which for that you must use the client software). You can also download entire directories as compressed zip files. However, you can’t upload, delete or restore files via the online interface.
The Dropbox website is where you manage most of your account, as the client only syncs data. You can do almost everything with it, including uploading files, making new directories, moving files, sharing files, deleting files (including permanently deletions), restoring deleted files and file reversions, and managing all of your account settings. The maximum file size you can upload via the Dropbox website is 300MB, but however you can upload files of any size using the client software.
Dropbox also has a great online photo gallery system that allows you to create and share photos with anyone (see sharing). For example, check out my “Mittens” photo gallery with pictures of my cat here: https://www.dropbox.com/gallery/21922853/1/Mittens?h=9b7b78
Both Dropbox and SpiderOak have ways to share files. I’ve found that Dropbox is the best for sharing files, unless you wish to share entire directories with anyone online, or need to share a directory outside of your Dropbox folder. If so, use SpiderOak.
Dropbox has a lot of ways to share files.
If you wish to share a file with anyone (even people who don’t use Dropbox), drop any file into the “Public” folder in your Dropbox, and then right click on the file, and then under Dropbox click “Copy Public Link”. That will copy the URL to the file. Then simply share the URL with anyone you wish. For example: https://dl.dropbox.com/u/21922853/HelloWorld.txt
You can also create and share a photo gallery with anyone. To do that, all you need to do is make a new gallery by going into the “Photos” folder in your Dropbox, and create a new directory with the name of your new gallery. Then just drop your photo files into it. I’ve got it to work with PNG, JPEG, BMP, and GIF. Then right click on your gallery folder and under Dropbox, click “Copy Public Gallery Link”. You can then paste and share the link with anyone. Example: https://www.dropbox.com/gallery/21922853/1/Mittens?h=b06a96
You can even share a folder and have it sync between accounts, so you could share a file with your friend, and the file would instantly download to your friend’s PC! To do that all you need to do is go to dropbox.com, login, click the sharing tab, click “Share a folder”, answer a few questions, enter your friend’s email address, and then dropbox will email your friend the sharing request. If your friend accepts, then all the files within the folder you shared will be synced between both of your accounts! For example, I made a folder that I share with my younger brother, Zachariah, so any files I put in that folder, will sync to his laptop, and any files he puts in will sync to my PCs. Note: When sharing a folder this way, any files within the folder will take up space on BOTH of your accounts!
SpiderOak seems to have only one way to share files. To share files, first open the SpiderOak Client, select the folder you want to share in the “Back Up” tab, get a ShareID, then under the “Share” tab create a new share. You then can send the link to the ShareRoom to anyone.
To access a SpiderOak ShareRoom, go to the link in your web browser or go to spideroak.com, click Share Login, enter the Share ID, and the Room Key, click open and you’re there!
SpiderOak shares have a “photo” view, but it doesn’t seem to work.
Remember: Only share files that are legal for you to share!
I think both SpiderOak and Dropbox are great services.
But from my experience I believe Dropbox is best at syncing data across your PCs, and file sharing (especially when it comes to pictures). SpiderOak is definitely the best for secure online backup.
Because I only want to sync and share data, and have my own backup system, I will stick to using Dropbox for now.
If you are reading this to decide which of these services is best for you, and after reading this you are still not sure, then go ahead and try both of them out yourself. After you decide which is best for you, both services allow you to remove your account if you no longer want to use it.
P.S.: If you want to get Dropbox, then go here: http://db.tt/ziZ9GpG, and we will both get 250MB of extra free space! 😉
WOW! That was the longest blog post I’ve ever written! Over two thousand words! I even had to spit it up to make it viewable! 😀
