Jungle Disk is an online backup tool that stores its data in Amazon S3 or Rackspace Cloud Files. It was highlighted by Amazon as one of the earliest S3 clients. The basic Jungle Disk software is sold as a monthly subscription model, and the customer is billed directly by Amazon for data storage and transfer.
Jungle Disk can periodically back up selected files or folders. It provides a local webdav server and a local web interface that synchronize to the user's S3/Cloud Files account, optionally encrypting backed up data on the client side. For a monthly fee, the company will provide a hosted web interface and more advanced backup functionality.
On October 22, 2008, Jungle Disk entered into an agreement to be acquired by Rackspace Hosting, Inc. Rackspace purchased Jungle Disk in order to expand their cloud hosting services. After the acquisition, Jungle Disk's development and support slowed down until they halted, although it's still possible to purchase the services.
- The lack of a Message Authentication Code means that file corruption (accidental or deliberate) or arbitrary file content insertions will not be detected
- The use of MD5 as a Key derivation function makes it easy to perform a brute-force attack on the Jungle Disk password.

- "If the people running the underlying storage service (Amazon S3 or Rackspace Cloud Files) know the contents of a file stored via Jungle Disk, they could transform it into anything they want — planting files which are dangerous (e.g., viruses) or even illegal (e.g., child pornography).
