Cabri Data Storage System

Cabri enables fast and secure data synchronization between people, medias and places.

It is mainly available as a command-line tool, but also provides an API (Golang or REST) for simple data storage.

Cabri is currently in beta release. A GUI is under development.

Documentation links are available at the bottom of this page.

Simple presentation

To make it simple, Cabri can be compared to the synchronization command-line tool: rsync

• using HTTP instead of SSH for remote access
• enabling unidirectional or bidirectional synchronization
• providing synchronization between local files and S3 compatible object storage
• but also with a data store on local storage
• providing in both cases data historization, deduplication or encryption, on a system neutral storage system
• and enabling multi-user data sharing through remote server
• taking care of data confidentiality in the Cloud or any unsafe environment, relying on public keys for data encryption and related sharing

all of that as a no-dependency single binary of less than 30 MB.

To get an idea, have a look at the quick start.

Tooling

• a Golang or a REST API are available for access to data storage services
• a basic configurable scheduler is provided, enabling automatic data synchronization among users, or between users and hosted applications for the support of DevOps practices

Implementation information

• Most actions are performed in parallel, synchronization is fast if the infrastructure provides enough resources
• Cloud storage is natively "eventually consistent" and Cabri takes care of not trusting successful updates
• Cabri makes use of indexes for fast synchronization or data retrieval, indexes may be rebuilt if broken
• Encrypted data is only decrypted on the user endpoint even when using a remote http server
