About Duplicity
Duplicity produces encrypted, signed tar volumes using GnuPG and the rsync algorithm for incrementals, then uploads them to a long list of back ends including SSH, FTP, WebDAV, S3, Google Drive and Backblaze. Only changed data leaves the machine.
Strengths
- Encrypts and signs everything before it leaves the machine
- Supports a very wide range of remote storage back ends
Limitations
- Long incremental chains make restores slow and fragile
- Periodic full backups are needed to keep chains manageable
