When utilizing Disk Utility (in my case, in MacOS Restoration Mode), to run First Support on a Time Machine backup on an exterior onerous drive with a purpose to confirm the integrity of the backup – is it essential to run First Support on each the APFS quantity containing the backup, and the APFS container that holds the amount?
Once I first run First Support on the APFS quantity and subsequently as soon as extra on its container, this seems to carry out primarily the identical integrity verify twice (e.g. if there are 10 Time Machine snapshots, it appears like these are verified twice).
Nevertheless, I’m not assured of what the right course of is, as a result of I suppose it is potential that the APFS quantity vs. container verifications verify various things regardless of having related output logs. Moreover, I all the time run First Support additionally on the Bodily Disk; this seems to carry out different verification capabilities.
This Apple help article does maybe recommend that one ought to run First Support on every quantity and container, however I nonetheless discover the language ambiguous. In case verifying the APFS container additionally verifies the amount, that is very redundant.

NB: Moreover, relying on the reply to this query, is there any purpose to imagine that the sequence for verifying the volumes & containers of the inner Mac SSD, ought to be any totally different from the sequence of verifying Time Machine volumes & containers?
