Tip: The allocation unit size on most NTFS and ext3 volumes is 4 KB. This allows for block-level deduplication.
Other examples of allocation unit sizes allowing for block-level deduplication include 8 KB, 16 KB, and 64 KB.
File-level backup
Deduplication of a file is not performed if the file is encrypted and the In archives, store encrypted
files in decrypted state check box in the backup options is cleared (it is cleared by default).
Deduplication and NTFS data streams
In the NTFS file system, a file may have one or more additional sets of data associated with itoften
called alternate data streams.
When such file is backed up, so are all its alternate data streams. However, these streams are never
deduplicatedeven when the file itself is.
