Hi
I bet we all battle with backups, are we doing enough, is it robust enough, is it costing too much? should i do more, etc. You can ALWAYS do more, but you gotta live life as well.
Well finally i have a system that works for me, here it is, whats your system?
macbook pro with 500Gb SSD
After a shoot i transfer the images to my mac, and dont delete the cards for a few days.
I run continuous cloud backup, so they start drip feeding to cloud storage straight away. I have about 35Mb download and 8mb upload speeds)
Ill run a local data (my profile) backup twice (ie once a week, or more frequent if needed), on two separate portable hard drives, so they are a copy of each other (to all intense purposes)
I also run timemachine on a 3rd drive once a month.
When i need space on my mac i delete older shoots, knowing they are stored in three places.
When the portable drives get full, ill park those and get two more and start again.
I've never lost images, but i feel i am as robust as i need to be.
Additionally i have a 256Gb storage card in the side of my mac, great additional (always with me) storage and it doesnt stick out.
