Data size / change sizes 10 11 Relative to [Cryptomator](Cryptomator.md), CryFS provides better privacy by limiting visible metadata, but can be slower and doesn't support concurrent accesses from multiple devices. 12 13 With CryFS: 14 15 > An attacker sees only uniformly-sized encrypted blocks with no visible organization 16 17 [https://www.cryfs.org/comparison](https://www.cryfs.org/comparison) 18 19 One concern is by backing up, say, 1.76Gb more data to a cloud server it can be quite obvious what that data might be in the context of what you are doing. Depending on your threat model, backing up dummy data alongside real data may be warranted.
