How to keep my backups safe from ransomware?

One of the first pieces of advice given when it comes to protecting against ransomware is to make sure to have backups of everything. Great advice, but are backups safe from ransomware? How can backups be protected against ransomware?
keep them disconnect from computer or online storage not unless you need them . use antivirus protection for back up files
Do not keep them on your computer or online. External hard drives are the most reliable ones when protecting your data. Besides, you should install a reliable anti-spyware and keep it up-to-date.
From PC World:

"As the ransomware quietly encrypts your files, your backup program will likely back up the files in their newly encrypted, and therefore useless, versions. So you need a program that does versioning—saving older versions of your files. That’s not too much of a problem. Most backup programs have this feature.

But even those older versions will be useless if the ransomware succeeds in encrypting all the files on your backup drive. That’s one reason why I recommend keeping the external backup drive connected to the PC as little as possible. Once a day, plug it in, run your backup program of choice, and safely remove it.

If you back up in the background to a NAS, back up the NAS regularly."
There are a few things you can do to increase your backup data's safety. If you use a backup software make sure it has versioning feature turned on. This will prevent the backups files getting overwritten with encrypted files. Your cloud backup takes some time to overwrite files and you might be able to retrieve a clean version as well. You might also want to have a secondary backup such as an external drive. Connect it only for the time you are running a backup. This way if your machine is infected, you car clean out the randsomware and retrieve your documents from the backup.
