It appends the date:

backupExtensionFor: aString
	| timestamp |
	timestamp := TimeStamp current.
	^String streamContents: [ :stream |
		timestamp date printOn: stream format: #(3 2 1 $- 1 1 2).
		stream nextPut: $..
		stream nextPutAll: (timestamp time print24 collect: [ :each |
			each isDigit ifTrue: [ each ] ifFalse: [ $- ] ]) ].
