I didn´t intend to overwrite any files: /raid certainly wasn´t in use at the time. > Why would your restore to /raid/home/user be affecting things under > /var?

The folder I was trying to restore was a harmless one in /raid that should have nothing to do with the rest of the system as far as I know... It's just the place I store the /home of a completely different system. rsync is not really an alternative for me because at the time the backup runs usually only the server is running, not the client (my desktop). >> >> Does anyone have a clue what is going on here, and possibly a way to >> fix my system? >> Any help very much appreciated, > > How have you configured it to back up and restore localhost?

But these weren´t selected to be restored. I am a little bit further: I found that all applications depending on Perl are broken, and I found this in Backuppc log: 2011-12-08 20:17:37 Started restore on localhost (pid=11576) 2011-12-08 19:28:11 localhost: Can't locate Carp/Heavy.pm in @INC (@INC contains: /usr/share/backuppc/lib /etc/perl /usr/local/lib/perl/5.10.1 /usr/local/share/perl/5.10.1 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /usr/share/perl/5.10/Carp.pm line 39.

I am starting to suspect that my Perl is messed up, because everything that uses it is broken. I've tried to re-install its packages but no luck yet. ------------------------------------------------------------------------------ Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of discussion for anyone considering optimizing the pricing and packaging model of a cloud services business.
