AWS CloudHSM vs CrashPlan: What are the differences?

AWS CloudHSM: Dedicated Hardware Security Module (HSM) appliances within the AWS cloud. The AWS CloudHSM service allows you to protect your encryption keys within HSMs designed and validated to government standards for secure key management. You can securely generate, store, and manage the cryptographic keys used for data encryption such that they are accessible only by you. AWS CloudHSM helps you comply with strict key management requirements without sacrificing application performance; CrashPlan: Data protection software for endpoint devices. It runs continually in the background of a device, providing constant backup of new files. Any time a new file is created or an existing file is changed, the product adds the file to a "to do" list.

AWS CloudHSM and CrashPlan can be categorized as "Data Security Services" tools.

Some of the features offered by AWS CloudHSM are:

• Protect and store your cryptographic keys with industry standard, tamper-resistant HSM appliances. No one but you has access to your keys (including Amazon administrators who manage and maintain the appliance).
• Use your most sensitive and regulated data on Amazon EC2 without giving applications direct access to your data's encryption keys.
• Store and access data reliably from your applications that demand highly available and durable key storage and cryptographic operations.

On the other hand, CrashPlan provides the following key features:

• Restore and back-up Files from anywhere, at anytime
• Protect every version of every file, forever, with no limits
• Protect critical data that lives on employee endpoints.
