Backup system advice please

[mark8par]

I have a TS453B and have been looking at the way i backup my data.

Currently have all macs and iPhone, the current backup i have setup is using Time Machine to the Nas and iCloud, i also use a Carbon Copy Clone to backup certain files that are important so as to have something separate.

I am looking into making this simpler and think i maybe better off switching to google cloud and using something like HBS to backup my nas to it but im unsure, can anyone help me simplify this? It would be much appreciated.

Thanks
Mark
