Best backup practices in light of ransomware encryption on external drives

What are the best practices in light of ransomware attacks. I've had a few local non rotating backups get bricked because of ransomware. I do have remote backup, but is everyone resorting to rotating backup drives?

"everyone resorting to rotating backup drives?"

Huh?  This is a best practice - rotate backup media... why wouldn't you "resort" to it? You should have offsite and offline backups.

Lee, we have onsite and offsite backups as a rule of thumb. The problem with rotating backup drives is that employees eventually forget to rotate, and sometimes quit rotating them all together. I was just see if there is a better way.

Thanks for your input, thats exactly what I wanted to verify.
Thank you for the update and I was pleased to help you.
So I assume you're using modern technology (virtualization).  If so, you backup the VMs.  I use Hyper-V and replicate to another server.  From the other server, I run backups.  No user has access to the hyper-V hosts so neither does ransomware.  Plus I replicate off-site and run seprate backups.  If your data is important you do EVERYTHING you can within reason.  It's insurance.  And while you may be the safest, everyone else are risks to your safety so you have to be prepared.
Had to add a very easy fix for almost all ransomware that tries to encrypt your backups: have you backup nas use a username/password to access the share. Run your backup software with This user. Only give permission to our backup software user, not your main user.

So many times I've seen the nas be an open share because that's the easy default setup, so the ransomeware can easily encrypt the backups.

Of course, cloud/off-site is still a good idea, but this simple change can make recovery much faster.
