No, but wait for a while for the mirrors to refresh themselves and resync 
later.  Hopefully, what ever package/version you couldn't download would be 
updated for synch-ing by then.

Of course, I'm only liberally interpreting your question to deduce what the 
problem might be, because you didn't tell us.

Only be restoring from a previously made backup or another computer that you haven't synced yet.

Do you steal taglines too?

You are right ;-)
My problems are:
a) my goal is a reasonably updated working system, not one in the 
latest fashion;
b) I had got to two RUWSs, an old Athlon xp (with riva TNT 2) and an 
HP dv5000z (Turion, ATI Radeon Xpress 200M);
-- updating my Athlon system was a mess *before* the new 
nvidia-legacy-drivers package, so it was worth updating the portage 
tree, but after the last "emerge --sync" many packages are blocked 
becasue they want a non-existent media-video/nvidia-glx (?) required 
(?) by an already installed and working qt-3.3.6-r1;
-- my laptop was perfect before modular X, then I ran into inadeguate 
support (by ATI and Xorg) of my video card.

I'm thinking about a "solution":
a) a "stable" root partition, including all directories used by 
portage (/etc, /usr, /var, and..? eventually all but home);
b) a "testing" root partition;
c) updating the portage tree in the testing partion, always emerging 
with the --buildpkg option;
d) updating the portage tree in the stable partition, and emerging the 
tbz2files created on the testing partition. only when the testing 
partition looks stable.

Any comments?
Thanks

Not a solution .. but the mirrors normally hold older snapshots of
portage, for instance:
http://gentoo.blueyonder.co.uk/snapshots/

Just an idea.

I apologize for my delay.
What have I to backup to be able to restore a previous sync?
Are /usr/portage and /etc/conf.d enough?

Theoretically, couldn't you just go to a Gentoo mirror and download a
portage snapshot from before you ran emerge --sync?

Yes, but I'ld like to return to a tested sync.
Perhaps I've been too concise ;)
I have two Gentoo systems, "stable" and "testing". I'ld like to test a 
new sync in the "testing" system, and:
a) if it does not work well to me, restore the previous working sync 
from the "stable" system, and wait for a new sync;
b) if it works well, copy the working sync to the "stable" system.
This is why I'm wondering if copying /usr/portage and /etc/conf.d 
would be enough.

emerge --sync only updates the portage tree, that is, the set of
available packages. it has no effect on what is actually installed on
your system. /etc/conf.d, on the other hand, contains configuration files
used my various Gentoo startup scripts. the two are not related.

If you want to test packages on one system before emerging them on the
other, just do so. emerge them on the test system, when you are happy,
emerge them on the stable system. I run ~arch on my laptop and my desktop
but tend to update packages on my laptop first, on the basis that I'd
rather mess that up than my desktop. Certainly with important packages
like baselayout, I emerge them on the laptop and reboot before trying
them on the desktop.

If you want to backup the portage tree, /usr/portage less distdir and
packages is what you need; but, as already mentioned, you can simply roll
back a day by grabbing yesterday's snapshot fro one of the mirrors.
