Multiple storage backends:

  • OpenStack Swift
  • Amazon S3
  • FTP, WebDAV, etc.

Above all, preserving users privacy:

  • Unlike most solutions, data is encrypted in your device with AES-256.
  • Nobody will ever access your files without your consent.
  • Access encrypted content from the most popular systems.

Multiple installations:

  • On-premise. Data and metadata are stored on the organization’s infrastructure.
  • Public. Data and metadata are stored on a public cloud provider.
  • Hybrid. Metadata is kept safely on premise whereas data is stored on a public cloud.

Horizontal scalability:

  • Unlike other open-source solutions, StackSync can accommodate large amounts of users.
  • Data replication to multiple nodes powered by OpenStack Swift.
