I was using Amazone drive for store my photos and videos and important document etc.. by comparing the annual cost, now I'm thinking to move to a USB external hard drive because those files I'm not accessing so often and sometimes when I traveling cost for mobile data to download files are high.
My plan is to buy identical two USB external hard drives and use one as a storage and the other one as a backup. But I don't like the idea of mirroring as a schedule task by connecting both drives to a computer and using a mirror software.
Can I use some external hardware to do the mirror part same as RAID 1 concept. When files save in to a one drive, other drive also should get the same change. Something like a
hardware hub or
As I feel this is a common requirement. Someone may achieve this before cloud storage get popular. Thanks in advance!
