I have a small server that boots from a usb drive and i would like to protect myself from the drive dying. I can't add another hard drive.

My question is: can i add one or two usb sticks of the same size and mirror the first one, so i can just unplug the first one when it dies and just reboot? I'd like to avoid reinstalling everything.

I am ok with a hourly or daily "backup" as long as i don't have to shutdown access to the server.

Thank you very much for your time and advice

Using Linux you can RAID USB devices. Google for mdadm and your distribution name to get to know how.

For linux there's no difference between USB block device and a SATA block device, so you just have to follow a regular tutorial.
