consider using a shorter full interval. 3 months full backups will give you 
roughly 90 incremental backups. If you loose one of these backups you might 
end up loosing data 3 month old (in the worst case).
You might also want to read the thread "Incremental backup, not accurate?" 
for other reasons why a long period of only incremental backups is possibly 
not a good idea. You can find the posts here:
