Recently, my Time Machine disk exhibited some filesystem errors. Disk Utility was able to correct them, but I don't trust the existing backup content much, and by extension, don't trust incremental backups made against that content.
I would like to force Time Machine to create a new, full backup (or, at the very least, an incremental backup while actually comparing all files and their content) without destroying the old backup content. I know I can destroy the existing backups and go again, but I'd rather preserve the history, imperfect as it may be.
How can (or, even, can) I do this?
