The Debian English-language backports wiki FAQ suggests (to find
all backported packages on a given machine):

https://backports.debian.org/FAQ/

 dpkg -l  |awk '/^ii/ && $3 ~ /bpo[7-9]/ {print $2}'
 (works here--outputs the package name without version)

 aptitude search '?narrow(?version(CURRENT),?origin(Debian Backports))'-F '%100p'
 (produces no output here though I have one backported package).

The French (ah, the French) backports FAQ suggests:

https://wiki.debian.org/fr/Backports

 dpkg-query -W | grep ~bpo
 (works here--outputs package + version)

Then there is the '/var/log/apt/history.log' also, which might be of
great utility in this affair.
