It's A Digital Disease!

I have one main NAS of 4TB and other random unused HDDs that I want to use as cold storage to backup one a month or less and move to another house.

I'm looking for a solution that will allow me to

• spread the storage across the HDDs like a "software RAID" handled by a software that keep track of the where the files are

• can SYNC (like a mirror) the updates files/folders

• HDD will be connected one at a time via USB

• can restore/resume the backup process if something happens

I tried Macrium Reflect that seem to support some of the features but once I was changing disks an error occurred and the backup stopped with no way of resuming. I had to start again (tens of hours).

I know this is a very unreasonable way to do things (especially the sync part) but I don't want another NAS and I don't want to use software like FreeFileSync where I manually select the folders to copy, what happens if one older folder becomes bigger and there's no space left on a HDD? It's too complicated to manage.
