Important update for all users, which addresses several bugs in setting the maximum size of sparse bundles.
How to set the total size, and band size, for your sparse bundles, with calculation of the critical band size.
This can now be incorporated into your own scripts, to check the integrity of important files automatically.
Time Machine can’t make backups to a disk formatted in APFS. Oh yes it can – and here’s how you can do it too.
Is it better to make sparse bundles ‘snug’, sizing them so that they don’t have as much free space? What if you then need to resize them?

Can you use error-correcting code to repair very large files, for example of around 20 GB or more?
An efficient means of storage with many uses, but riddled with bugs and shortcomings. Explains how to compact and resize them, and more.
Simply having ECC enabled doesn’t mean that damaged files can be recovered. It appears promising, but needs careful real-world evaluation.
We assume what we know to be impossible, and pretend that just making ‘safe’ copies of important documents will preserve them for the future.
