A comment on Mac OS X - The state of the file system (2011).

The paragraph about the hard link errors propagating from one backup to another in Time Machine is pretty scary.

Is there any known solution to this problem? Would running something like Disk Util from time to time detects the errors and fix the filesystem?

Depends on the cause of the corruption. If the physical drive is going bad, then diskutil should at least report some errors. But HFS+ doesn't checksum anything. If you have a flaky controller or just an errant solar ray flipping a bit, there's nothing diskutil can do about it. A 0 is as valid a bit as 1, so as far as diskutil can tell, all you did was save a change to a file somewhere.

You can verify your time machine backups periodically though.
