Episodes like Threshold and that one where the Enterprise crew turn into children come to mind. The latter actually involves transporters.
They don’t usually revert the crew using the backup data, though. They just program it to make changes to their bodies, like removing things. It wouldn’t be any stranger than removing an alien pathogen.
The backup data, I think was only used for Pulaski when she got the ageing disease (where it might have been a reference pattern to correct errors, and they had to actually compare with a known good genome), and for Tuvix.
We do also know that a bad transport can’t just be retried either. The Motion Picture had a transport go wrong, and Starbase One couldn’t just restart the transport with backup data, or repair what they got back. Similarly, Scotty couldn’t just load up Franklin’s backup from the Jenolan’s computers and transport him in either.
Failed transports generally seem to stem from not having quality data to reconstruct with. Not getting a good enough sensor lock, damage to the buffer corrupting the data, etc.
The entire point of a backup is to overwrite and replace bad data, though. If a backup was kept, it would logically follow that it would be possible to overwrite the damaged parts of the pattern, since we know that transports can succeed even if a portion if the pattern is lost.
Geordi specigically brings up it being impossible to materialise Franklin because his pattern had degraded too much, not that it was degraded at all, and would suggest that there’s a threshold before repairs are no longer possible.

Not always they use the healthy backup. Check out dr. M’Benga’s daughter.
As previously stated, I’m leaving NuTrek out of this discussion entirely as NuTrek doesn’t care about continuity in the slightest.
