Hi Peter, thanks for that tip. As it happens, through the night, the TM backup was intelligent enough to figure out that it was actually backing up data already present and so no duplication and it successfully concluded. Not sure why it went into this position of not recognising the old backup file at least initially.
All sorted now.
