1. easy setup: Duplicacy is built using golang. It is convenient to setup around all platforms with dependencies.
  2. support object-based storage: borgbackup needs installation in two ends. Sure with rclone, we can upload backups to clouds. But there will be no deduplication among backups. Because they are already compressed and encrypted into a different structure. #3 is a elegant way to solve this.
  3. cross machines deduplication: This means no matter how different those backups are, one single file will be only stored once.
