Mmmmm. ZFS. Sweeeet :-)
The point wasn't just that I wanted to backup the repository, it was that the integrity of the repository which is my backup of the real data needs to be tested every time it's updated.
Are you saying mercurial is not transactional? That's a little bit scary.
It's transactional; it has atomic commits and all the goodness you expect. I'm saying if you sigkill -9 the server while it's in the middle of a push, things can go horribly awry in a way that isn't detected.
I think it should be detected, but...
I thought it was a distributed system. Calling it "server" seems to be a stretch.
I'd say kill'ing -9 the pulled side should give an error in the pushing side, or the system can't be called transactional.
I still find really scary that a revision control system ends without a "proper" error when it breaks and after it is broken.
Very helpful! I've just signed up for a VPS (Virtual Private Server eg a Xen DomU) with limited memory and this is something I worried about. Thanks :]

Note that system(...) in Perl returns 1+ in case the command failed. Perhaps you wanted:
system('hg verify') and die "$!";
