I have seen this posted elsewhere but despite being a good backup tool kdat does not restore individual files correctly. Sometimes it restores nathing but thinks it did something and sometimes it restores totally wrong files then the ones it said it would restore. Since the index file for the backup is there this is a problem of not counting something correctly in restore, perhaps links? I have seen the same problem reported so I know I am not the only one. Such an important tool needs to be more stable. I am not able to find the source of kdat-2.0 since I presume it is taken over by kde e.g. home page of kdat has no new development. Thanks,
This is fixed in 2.0.
