[OT] tar command

[Ralf]

Does anybody know something about tar?

Very interesting, I deleted a broken Maverick-Natty-Upgrade-Install by
# rm -r *, then I copied a backup archive and restored Maverick from the
backup by tar xzf *, restoring Maverick takes between 3 and 4 minutes
only.

How is this possible?

The restored Maverick seems to be ok, at least Email etc. is ok, the
size, 6.76 GiB is correct.

An amazing voodoo trick.

I didn't know that it's that fast.
