Q: How does the deduplication feature save space on my NAS?
A: BmuS uses the rsync --link-dest feature. When a file hasn’t changed since the last backup, BmuS creates a “hard link” to the existing file instead of copying it again. Hard links look and act like real files but point to the same data on the disk. This means you can have 10 full daily backups that only take up the storage space of one full backup plus the small daily changes.
