Backup Plan Suggestions / Tips - Required @James Dyke - Cloud Berry was recommended to me as a cheaper alternative that supported multiple methods of backing up to cloud storage as well as onsite storage.
@Matt - Thanks for the links and I think the part that I have been missing this whole time is... (However it is important to keep in mind to do a regular full backup to save on space, increase recovery time and purge older versions.)
I have not being doing enough full backups in order for the retention policy to work. So basically it just fills the NAS up within about 2 months.
So the new settings I am running with are incremental backups every 2 hours during business hours and also a full backup every 1 month. Also the retention policy is set to delete versions older than 3 months (file version age).
Do you think these settings would work correctly or should I set them up differently? Thanks for your help thus far! :)
