Yeah, block level deduplication is not useful for files on a typical consumer laptop. I can imagine it's even less useful for files on iOS devices.
However it is often great for virtual machines and other software development related things, as long as all the underlying block sizes and alignments match.
You really do want strong integrity guarantees though. One corrupted block can cause a lot of damage.
- Scaevolus 7y agoThe filesystem encryption used on iOS probably makes deduplication even less effective.
- vardump 7y agoDepends on the layering order. You can do both dedup and encryption in the same time, if the encryption occurs on a lower layer.
- eridius 7y agoEncryption in iOS is per-file. I'm not sure the OS really wants to go ahead and individual decrypt large numbers of files just to check if there are any duplicated blocks.
