See: Working with APFS Volume GroupsĬruft - Another term for digital detritus, e.g. While not identical (some caches should not be copied as they must be rebuilt on a bootable backup, and files like trash are excluded), clone is a common word used for a CCC bootable backup.Ĭontainer (APFS) - A container on an APFS formatted drive is similar to a partition, but allow several volumes to share the space in the container more flexibly.
