So I’m not really a selfhoster per say - but I run 2 NAS at home and I am working my way toward it. I don’t really need my stuff open to the internet so I just use it on my LAN.
However I do have a lot of data, and I’m constantly backing things up. My question is - I have the following setup:
- Computer hard drives
- These backup to my NAS
- I have a separate HDD in an enclosure I plug into the NAS directly and copy my data onto every few months to put in my safe.
- Some cloud storage for very important smaller stuff (pictures)
My main question is - what is the best way to copy off new data from my NAS (Synology) to my “cold storage” drive, without recopying everything every time? is there a way to detect the files that exist on both and only copy new ones? I’ve always had this question when doing backups and it seems to always be overly complex.
You guys are very knowledgeable so I’m sure someone has dealt with this!
I do use duplicati for my desktop and its great.
This is more and issue of having matching, linux, and 1 windows (soon to be linux) pc. So mixing and matching is hard. I have 1 nas for movies and music and my other nas is for music production backup. That one auto backs up from my Mac.
So then, every few months I copy that nas onto another drive and put it in the safe. I guess I want a better way to do that other than plugging the drive into the nas and manually copying everytbing over.
