About:
S3QL is a FUSE-based filesystem that stores data and metadata in a cloud object store like Amazon S3, Google Cloud Storage, or Backblaze B2. It provides a standard POSIX-compliant file system interface, allowing you to mount cloud storage as a local directory. Key features include data deduplication, compression, and client-side encryption for efficient and secure storage.
Key Features:
  • Data deduplication and compression
  • Client-side encryption (AES-256)
  • POSIX-compliant (supports hardlinks, permissions, etc.)
  • Snapshots and immutable backups
  • Offline caching for improved performance
Use Cases:
  • Secure, encrypted offsite backups of local filesystems
  • Cost-effective archival storage for large datasets
  • Sharing large files across machines via a common cloud backend
Alternatives:
  • rclone – rclone syncs files to cloud storage, whereas S3QL mounts it as a local filesystem for direct access.
  • s3fs – s3fs provides a similar mount but lacks S3QL's built-in deduplication, compression, and strong encryption.
