My Time Machine backup scheme has become unusable - the backup can take days if not over a week and trying various methods of shutting off spotlight or stopping local backups, etc. has not changed anything - now my TM gets to a few hundred MG and just stops.

So, I need an alternative - but a disk cloner is not going to work for me because I might need to fish out and recover individual files to restore instead of the entire drive.

Can anyone recommend a TM alternative that supports file/folder level backup/restore or perhaps a method to kickstart TM and get it working properly again?
