Time machine issue solved

I had issues with Time Machine backups. After some time while backing up Time Machine gave me a finger: ". . . an error occurred while copying files to the backup volume" and a suggestion to repair disk. Nothing the error message suggested worked. I repaired disk, verified it and even formatted. Until I tried this tip.

I like this command

find . -type f -name "file_to_remove" -exec rm -f {} \;

finds a file by name or mask in current directory and recursively and deletes it :) From here.
