backup: witch table to play back in the database

I didn't use the zp-backup function and have some older db-backups.
Witch tables I can play back without getting trouble by possible security restrictions?
All or only images and albums? Or just some columns of both tables?
Anybody has some experience or suggestions?
I made something like database-refresh but nothing serious on my view ...
After anyhow my installation lost and mixed data:
110 img have no titles and description anymore, only their filename
and some of this img-datasets have now new id and album-ID's.
Even some album ID's changed.
The sort ist gone and some 100 imgs are unpublished.
Even one title is swaped ...
all imgs have exif-data inside, but I add & update this data from the backend for sure.
Never made the metadata-update because then my added data are gone,
because they where not written into the imgs, I think ...
thanx for help,
v 1.4.14
