From its outset, APFS hasn’t tested the integrity of file data stored on it. Would this be a good idea, or should macOS switch to the ZFS file system instead?
Dintch
APFS has no feature to check file data integrity. Dintch and Fintch are two apps that tag files with SHA-256 hashes to address this. New versions.
Minor updates to Spundle and Dintch. A bug in SilentKnight and LockRattler. Dropping support for El Capitan and Sierra, and a few obsolete apps.
How to do this using macOS and free tools. Introduces a new version of Dintch which lets you control its speed, particularly on Apple silicon.
Storage has to be reliable, efficient and resilient. However, efficiency and resilience oppose one another. What’s the best solution? New file formats, CRC in the file system, or what?
For many users, it’s essential to be able to check the integrity of the data which are in a backup. This feature has changed when backing up to APFS.
What are checksums, CRCs and hashes? What is required for a hash to be cryptographic, and how any of these affect your Mac? Some answers and explanations.
How can you check the integrity of important files you have stored in iCloud, or in a Time Machine backup, such as those made by Big Sur to APFS?
The command tool member of the Dintch suite for tagging files with their SHA256 digest, to keep a watch on their integrity.
They now run on macOS from El Capitan to Big Sur, on Intel and Apple Silicon Macs.
