Backup question

Hello All,
I have a database that I am currently performing backup and incremental
backups.
If I were to add an extra table to the database or modify an existing table
with a few columns, would that imply that I would need to perform a full
back.
Thanks

Only if you don't want to wait for the next backup - modifying a table
is like making any other change in the database. If you've made a large
number of changes which would take some time to redo manually, and if
your database isn't very big, it might be worth making a backup so that
in the worst case you don't have to reapply the changes by hand. But
apart from that there are no special considerations.
