Only if the stuff is fit for purpose --it offers NOTHING extra to what you can do yourself - and most of this stuff is usually out of date before it's even released.
Backups on cheap external HDD's are the way to do this stuff -- if it's NOT on the computer even the most sophisticated Ransomware on the planet can't get at it.
This is where CLOUD also could have vulnerabilities if you really get stung via a sophisticated piece of Ransomware -- that's why I'll ALWAYS have at least 2 sets of Backups on OFFLINE media --HDD's are cheap enough these days - imagine re-creating - even if it were possible -- several TB of Music and video files for starters !!!!.
If you do get Ransomware --simply power off IMMEDIATELY the computer - don't power down via software - just disconnect mains or if Laptop hold power off button until computer powers off. Disconnnect LAN / Wifi too -- if that's too complex simply switch router / cable box off.
Boot up your recovery / restore software from external media and restore. Macrium is good for this stuff and the FREE version is probably good enough for typical home users.
If you are 100% paranoid also format the computers internal HDD('s) before restoring. Format from a recovery disk - not from within the infected (or potentially infected) computer of course. I.e don't boot up the computer and format HDD's before restore - format from a recovery media - boot from external DVD / USB.
Easily solved and just poke the proverbial 2 fingers at the Ransomware site !!!!.
Note -- why people even bother with Cleansing A/V software to me seems just pointless - these days on decent gear an OS restore - especially if the OS is on an SSD will probably take around 0 mins (max) --A/V cleansing can take HOURS (or longer) and you can't guarantee it's 100% successful either.#
Restoring several TB of data will take longer but you can do that overnight etc. Usually the data drives won't have been touched though if you IMMEDIATELY switch off computer if you get a ransomware warning.
AGAIN - ALWAYS TAKE REGULAR BACKUPS AND KEEP OFF LINE.
You can keep backups on a LINUX type NAS - but even a NAS needs to be backed up from time to time. You always need to have at least ONE SET OFFLINE. You need to ensure though that only root user can access the backup HDD's otherwise the ransomware could hose it up --- the easy way is to ensure that those HDD'S have NO Windows access until the backup is run.
Personally when I backup my stuff to NAS from Windows I run an OS from a bootable USB stick -- the OS on the stick can access the NAS so no problems.

Luckily I never had to deal with ransomware and with Thunderbird you must allow to see the full content of an e mail first. And I never open an e mail I don't know and even the ones I do know I think twice before opening them.
