the examples are in the guide. there are lot of options as it is basicall a query ona database which is containing many atributes to display so really hard to tell what somebody will use in production.
if you are into gui you can do it in Media\Save sets or do some reports using the native console reporting features if you are on >=7.4.X
example i use if somebody asks me if a client has been backed up last night
mminfo -c client_name -t yesterday -o tnc
or list all backups performed in last 7 days
mminfo -t "7 days ago"
the same can be acomplished like this
minfo -s backup_server_name -t "7 days ago" -q "valid,!incomplete" -r client,name,ssid,ssflags,sscreate,level,totalsize -o cnt
you can put a separator- ; to the output so you can easily import it to excel
minfo -s server -xc; -t "7 ago" -q "valid,!incomplete" -r client,name,ssid,ssflags,sscreate,level,totalsize -o cnt >file.csv
