Comparing cloud storage services: cost, size, security

Comparing cloud storage services

By now, most businesses are using some form of cloud storage to either back up files or share documents, be it through the popular Dropbox, Mozy, or Google Drive, but not all cloud storage services are equal – some are more costly, while others are more secure.

Leading consumer and small business resource NextAdvisor.com has rated and reviewed cloud storage services, particularly those that take extra steps to keep confidential data safe and in one centrally located place even if a device is stolen.

NextAdvisor.com Editor Chris Rancourt takes it one step further and gives more detail to AGBeat readers by offering pros and cons of some of the most secure cloud storage options:

1. Spideroak

Pros: Spideroak offers some of the highest encryption security out of all the major cloud storage services. Spideroak takes the extra precautions to encrypt your information and security keys at all times, preventing your information from brute force and pre-computation attacks against your security key. The only way to decipher this information is through your unique password. Spideroak’s zero-knowledge privacy policy insures that not even their employees will have access your password or information, making Spideroak one of the most secure cloud services on the market.

Cons: The drawback to all this extra security is being responsible for all of the encryption keys and passwords. If you are one of those people who constantly forget your password, this may present a problem as the Spideroak staff can not help with password recovery due to their zero knowledge policy. So if you decide to go with Spideroak, make sure that you keep your password somewhere safe.

2. Sugarsync

Pros: Much like other cloud storage services, Sugarsync encrypts all your files to protect them from falling into the wrong hands. When transferring your data, the information goes through transport layer security (TLS) using 256-bit AES encryption. One of the best features of Sugarsync’s security is their remote wipe. The remote wipe is a critical tool to protect your information if your computer, phone or tablet ever gets stolen. With the remote wipe, you can log on from any computer and remotely delete the files from that stolen device. This way you can be in control of your information even when it’s stolen.

Cons: The downside is that if someone steals your device and you are still logged in to Sugarsync, they will have access to those files until you activate the remote wipe. The other drawback is that if someone is able to gain access to your password or account, your files are not stored as encrypted files so they will be easily readable for those who have hacked your account.

3. Mozy

Pros: Mozy’s Titanium Cloud is one of the most sophisticated cloud storage security systems out there and will protect your information from virtually any type of intrusion. Mozy is protected by military-grade AES encryption prior to data transfer, as well as 256-bit AES encryption with SSL-encrypted tunnel for file transfer with an optional 448-bit Blowfish encryption key. Not only will this keep your information safe while your information is stored, but also while it is in transit when uploading or downloading information. Mozy also offers the ability to use your own encryption key for added security as well as a deactivation ability that works much like Sugarsync’s remote wipe.

The drawback to Mozy is that if you decide to use your own encryption key and lose it, it is not possible to decode your encryption. Mozy does not hold itself responsible for your personal encryption key so if you lose it, your information will stay in its encoded format.
