Perhaps set the versioned backed up file (version) name, date & time, to coincide with the date/time of the backed up file, rather then the date/time that the backup occurred?
It doesn't really matter, particularly.
But would it make sense to do?
abc.txt
(dated) 01/01/2020 02:01:00 PM
So now the (source &) backup shows:
abc.txt 06/24/2020 11:42:02 AM
abc.txt 2020-06-24 114202 (as its name)
& 01/01/2020 02:01:00 PM (as its date/time as stored on disk)
Would it make sense to name the versioned file:
abc.txt 2020-01-01 140200
(which would then coincide with the timestamp on disk) 01/01/2020 02:01:00 PM
