Bug#593430: apt should backup /var/lib/apt/extended_states
tag 593430 + patch thanks 2010/8/18 Steve Langasek vor...@debian.org: Now that apt stores information about automatic installation status of packages in its own file in /var/lib/apt/extended_states, backups should be taken of this file the same as is done for /var/lib/dpkg/status and /var/lib/aptitude/pkgstates. Now… :) (hint: included since APT 0.6.44.2exp1 released on 3 Jul 2006.)

Its easier now with snapshot.debian.net to recover the content coming from the official archive for any given time, but other more or less official archives aren't tracked by it (volatile, security, backports) and historical thirdparty stuff isn't always available either… Best regards, David Kalnischkies -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Yes, A shameless copy from dpkg cron should do the job. :-) Strangely, /etc/cron.daily/apt does backups of /var/cache/apt and *not* of /var/lib/apt, even though all information in /var/cache is supposed to be recoverable if deleted!
