Encrypted backups for Android.

Flashback provides encrypted backups to the cloud, giving you reliable access to your data along with the peace of mind that it's secure.

Cloud storage — done right.

Flashback allows you to backup your entire android system, as well as the contents of your SD card. By default, your data is stored in Amazon S3 — but everything that leaves the device is encrypted, giving you the reliablity of a storage provider like S3, but with the data security of Whisper Systems.

Efficient storage and data transmission.

Flashback's snapshot technology keeps track of what you've already backed up, so if a file doesn't change between one day and another, that file isn't backed up again. Flashback even keeps track of blocks within a file, so if a file does change, only the new parts are backed up, while the rest are reused. This gives you full coverage, without wasting bandwidth, battery life, or storage space.

Additionally, Flashback performs operations transactionally. If a backup fails midway, that transaction is rolled back, which prevents a partial snapshot from taking up storage space.

Manage snapshots across devices.

Flashback allows you to view, restore, delete, and backup data across all of the devices you own.

Strong encryption.

Flashback uses strong encryption so that you don't have to trust the integrity of your data with anyone — even us. For the cryptographers out there, see the technical details if you're interested.

Try it out.

Flashback is included with WhisperCore 0.4, a free download for individual use. A limited version of Flashback is also available for non-WhisperCore users through Android Market.
