About :
Feature-Driven Design
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 (file-level deduplication), and identical parts from different files must be stored as one copy (block-level 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 backup : Multiple clients can back up to the same storage at the same time
Backup migration : All or selected backups can be migrated from one storage to another
