I hope I'm not teaching you to suck eggs, but filesystems are often
remounted read-only automatically if the OS encounters errors while
writing. It sounds like that happened to your drive mid-backup, and that's
why rebooting fixed it – it got mounted as normal as part of the boot

It sounds like your backup drive is becoming more unreliable (which is a
less dramatic way of saying "could be about to fail"), which is why it
happened at different points in your backup. USB also has limits to the
amount of data it can simultaneously transfer, so if you're doing a lot of
other USB-centric stuff at the same time as your backup this could also be
a problem. 

If you have a second system you can plug your external drive into, you
could do some tests to confirm it is the drive that's causing problems. 

Hope this helps,
