Backing up .mozilla (firefox settings):

find ~/.mozilla/firefox/ -type f -name "*.sqlite" -exec sqlite3 {} VACUUM \;
find ~/.mozilla/firefox/ -type f -name "*.sqlite" -exec sqlite3 {} REINDEX \;
tar czvf ~/Backups/mozilla-backup.tar.gz ~/.mozilla --exclude=cache

This script first attempts to clean the sql database firefox uses, then creates a tarball of all the files in the .mozilla folder, except for the cache, which isnt needed and usually takes up most of the space. If for whatever reason you want to backup the cache too, just remove --exclude=cache

Backup .purple (pidgin) except for chat logs

tar czvf ~/Backups/purple.tar.gz ~/.purple --exclude=logs

Move /usr to a squashfs loop filesystem (archlinux only)
