Where is the time machine?

After several times unsuccessful hibernation, the JFS file system is screwed up by the forceful shutdown. There are some directories with weired access control in the portage, that cause the fsck.jfs exit abnormally. Eventually, I decided to clean up this morning using the ultimate way: format.

I did a full stage4 backup first, and then format the disk and tried to recover from the stage4 tar ball. Oops, here is an fatal error. It looks like the backup met some errors then exited with a success message. That is really not funny.

Anyway, I had a backup one week ago, it is old since I update the system everyday, yes, that is the typical Gentoo users’ behavior. But wait, I just got the second half of the split stage4 tar ball, where is the first half?
