Duplicity is a free, open-source backup tool that creates encrypted, incremental backups using the rsync algorithm. It supports multiple protocols like S3, SSH, and FTP for versatile storage options. Perfect for personal and corporate data safety, ensuring efficient and secure backups.
Overview of Duplicity
Duplicity is a robust backup tool that creates encrypted tar-format volumes for directories and uploads them to remote or local servers. By utilizing the rsync algorithm through librsync, it ensures that incremental backups are highly space-efficient, only saving the parts of files that have changed since the last backup. This makes it an excellent choice for Incremental Backup needs, providing bandwidth savings and faster backup cycles. It is designed for users who require reliable and efficient data protection without compromising on security.
With encryption and signing handled by GnuPG, Duplicity guarantees that your backups are secure from unauthorized access and tampering, fitting perfectly into Encrypted Backup strategies. It supports a wide range of storage protocols including Amazon S3, Google Drive, and SSH, making it versatile for various environments. Mature and reliable, it is used for large-scale personal and corporate backups, ensuring data integrity and safety across different systems and use cases.
How to Use Duplicity
To use Duplicity, start by installing it through one of the available methods such as snap, pip3, or from source code. Once installed, configure backup jobs by specifying the source directories, the remote or local destination server using supported protocols like SFTP or S3, and your GnuPG encryption keys. The tool will then perform incremental backups, creating encrypted volumes that only store changes, and you can schedule regular backups using cron jobs or scripts for automation. This workflow ensures efficient and secure data backups with minimal manual intervention.
