About:
Duplicity is a command-line tool that creates encrypted and digitally signed backups using librsync for efficient incremental uploads. It supports various backends including local filesystem, SSH, FTP, and cloud storage services like S3 and Google Drive. Its primary value is enabling secure, space-efficient off-site backups over potentially insecure channels.
|
Key Features:
- Incremental backups using librsync for bandwidth efficiency
- GPG encryption for data security and signing for integrity verification
- Supports multiple storage backends (S3, Azure, FTP, SFTP, WebDAV, etc.)
- Volume snapshots and data de-duplication
|
Use Cases:
- Automated encrypted off-site backups for servers and personal computers
- Securely syncing sensitive data to cloud storage providers
- Creating restorable versioned backups of critical system data
|
Alternatives:
-
restic
– Written in Go, generally faster, supports snapshots but uses a different repository model
-
rsync
– Faster for local/network sync but lacks built-in encryption and versioning
-
borgbackup
– Focuses on deduplication and local repositories, typically requires SSH for remote backups
