Proper backup does data independently from code, and proper devops is to always do an install from trusted source.
It is unfortunately very rare to find this in practice - everyone seems to be happy with just snapshotting live systems as a backup these days; and it works well enough as long as there is no lingering systemic corruption of data.
(And .... Excel, by mixing data with potentially malicious code, is beyond redemption. But good luck quarantining that in a modern suit controlled company)
