They're not daily backups, as you have noticed.
What are you concerned about backing up daily - databases? That's easy enough to do. I have a script that runs daily to dump my databases to local files which are then copied to off-site storage. Works great, lasts a long time.

I already have a job running for database off-site backup.
I need a daily backup of the files and media I'm hosting (25Gb and growing, too big to ship daily).

I will script this part too, at least for a subset of these files.
