Back-up suggestions

Thanks for that Graham I do keep my software information along with the license information in a paper file (old school), I started doing that back when I too had a system crash. I use too rely on my Mac Time Capsule to back up my computer (not my photo's) but it to past on. I'm not completely done working out my back-up solution's, as I am still considering how to protect my Computer programs, (thought of putting it onto a separate drive), or allowing the ThunderBay set-up to handle everything.

I think you can make a disc image with most back up software and this literally is a snapshot of everything on your computer - or that drive if there are several drives - at the time of doing it in one file. Using this you can restore a drive exactly as you saved it. I used to do them from time to time, but it should be done very regularly to ensure it is up to date. I think this is more important with the system drive as your profile will be constantly changing as software is used.

I'm not really bothered about anything other than my data and that is backed up weekly at the moment due to my being housebound because our covid regulations are restricting going out to only essential stuff. I do a second back up less frequently and am contemplating a third one.
 
Well I took the plunge and purchased the OWC Thunderbay 4 56TB 4- Bay Thunderbolt 3 Raid 5 Array unit, so it's to late if I made a bad choice. I don't believe I did so I'm going forward with a positive outlook. I wonder if anyone could clarify my thinking which is: regarding Raid 5 array is one disk your working disk and the additional disks share the data which if that working disk fails, by replacing that disk with a new one the others automatically rebuild your library, would this be correct? Also if this 56TB system (4 disks @ 14TB each), is using Raid 5 array my actual storage capability is limited to 14TB, would this be correct. Is Raid 5 a good choice for a single computer application or would Raid 10 be a better option? I'm sorry for continuing on this storage topic but I must add it is confusing enough but with the input of experienced members it has made it possible for me to at least get a foot hold on understanding. Thanks Ray
