Dragging a file to copy/move it from one location to another used to be simple. Now it’s complicated by iCloud, dropbox behaviour in AirDrop and Universal Control, and more.

Confused by this on APFS? So you should be, as it’s complicated by features like snapshots, sparse files, and the file system itself. There’s no single figure.
Tired of HFS+? Disenchanted by APFS? Why not copy or back up to a different file system? Here are crocodiles waiting to bite you.
M1 Macs are different, as they always start booting from their internal SSD. Basic configurations are simple, reliable with well-established disaster recovery methods.
A lot of what Time Machine does when making backups to an APFS volume remains a mystery. So far we don’t understand the magic used by Apple.
Track down all those duplicated files, and you could save yourself loads of disk space. Rather, you used to be able to. Why this doesn’t work so well now.
For some, inability to clone to the internal SSD of an M1 Mac seems disastrous. In reality, it could achieve little, and there are better solutions.
Cloning has been a popular way of creating external bootable disks. Now that CCC 6 can make full clones of disks for M1 Macs, is it a solution?
The first full backup is performed as a manual backup, and largely occurs in file-by-file copying from source to the backup store. It is more efficient than to HFS+, but differences could be less than 10%.
Sparse bundles, sparse files, and sparse matrices explained in a nutshell, and how a sparse bundle could have a band which is a sparse file containing a sparse matrix.
