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?
They readily grow in size up to their maximum. But getting them to shrink when contents are reduced isn’t as easy.
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.
Do you want ECC for your important documents? It’s available now, free, without the complications of ZFS or cost of RAID 6.
A nimbler version of Dintch is designed to drag and drop files and smaller folders to tag then and check their integrity.
More about checking the integrity of files on macOS, with a new version of a free utility, news of the next apps, and error-correcting code perhaps?
