WARNING

WARNING: At the moment, consider khepri as alpha quality software, it is not yet finished. Do not use it for real data!

Khepri

Khepri is a program that does backups right. The design goals are:

  • Easy: Doing backups should be a frictionless process, otherwise you are tempted to skip it. Khepri should be easy to configure and use, so that in the unlikely event of a data loss you can just restore it. Likewise, restoring data should not be complicated.

  • Fast: Backing up your data with khepri should only be limited by your network or harddisk bandwidth so that you can backup your files every day. Nobody does backups if it takes too much time. Restoring backups should only transfer data that is needed for the files that are to be restored, so that this process is also fast.

  • Verifiable: Much more important than backup is restore, so khepri enables you to easily verify that all data can be restored.

  • Secure: Khepri uses cryptography to guarantee confidentiality and integrity of your data. The location the backup data is stored is assumed not to be a trusted environment (e.g. a shared space where others like system administrators are able to access your backups). Khepri is built to secure your data against such attackers.

  • Efficient: With the growth of data, additional snapshots should only take the storage of the actual increment. Even more, duplicate data should be de-duplicated before it is actually written to the storage backend to save precious backup space.

Building

Install Go (at least 1.2), then run:

export GOPATH=~/src/go
go get github.com/fd0/khepri/cmd/khepri
$GOPATH/bin/khepri --help
