Going back slightly you can specify a script/program that will be run by dpkg at key points when packages are installed and removed. I never went beyond logging the parameters to a log but I remember at one point you get the location of the .deb file being installed. You could grab information from

LVM lets you create a snapshot where the mounted filesystem looks normal but under the cover it's using a journal and the original logical volume, e.g., /dev/mapper/vg0/home, is untouched. You can then perform your backup and when you release the snapshot the journal is written to the original volu

The simple way to create a restore point system ... ... is to mount / as an overlay FS, which you periodically merge (to remove prior restore points), condense into a squashfs (to take a point backup), or wipe (to restore to backup). This of course means /home should be its own partition. On Sun

You need to either have a local repository or download from the internet again. I've used 'apt-mirror' in the past to maintain a local cache but that was when I was building local systems with a minimal Debian installer.
