Duplicacy is a new generation local and cloud backup tool that supports cross-computer deduplication. It is free for personal use and source code is available to commercial users.
duplicacy is a new generation cloudbackup tool supporting 5 major cloudstorage providers (amazon s3, google cloud storage, microsoft azure, dropbox, and backblaze), as well as local disks and sftp servers (such as mac/linux computers or nas boxes). duplicacy is the only cloudbackup tool that offers all the following 7 essential features:
* incremental backup: only back up what has been changed* full snapshot : although each backup is incremental, it must behave like a full snapshot for easy restore and deletion* deduplication: identical files must be stored as one copy (filelevel deduplication), and identical parts from different files must be stored as one copy (blocklevel deduplication)* encryption: encrypt not only file contents but also file paths, sizes, times, etc.* deletion: every backup can be deleted independently without affecting others* concurrent access: multiple clients can back up to the same storage at the same time* snapshot migration: all or selected snapshots can be migrated from one storage to another
