The Reddit app is suggesting to back up your vault via cloud using Google drive. I highly suggest you do not do this.

Since the introduction of Reddit vaults, each Reddit user in this sub has the ability to open up their own decentralized wallet called a Vault and collect community points on the blockchain such as Moons or Bricks via upvotes every month.
Since this wallet is self managed it is truly your keys your crypto and you're responsibility to keep your own seedphrase backed up and secured.
The best way to back up and secure your seed phrase is to write it down on paper and store in a safe location, although some may find the 2 minutes of work a little annoying and some users don't do this at all.
Reddit has an option of backing up your seedphrase on the cloud via Google drive, ironically metamask mobile and coinbase wallet also has a similar option of backing up your seedphrase via Google drive or icloud.
Seedphrase backup via cloud is one of the worst ways to store your private keys, since it's on the internet this allows a path for hackers or scammers to gain access to your seedphrase.
People trying to steal your crypto are relentless these days and spend a lot of time and energy into trying to steal your funds via phishing, social engineering, sim swapping, scrapping data breach lists on the darkweb, some groups have turned this into a full time business, hell even North Korea does it.
It won't happen to you? We recently had someone in this sub lose 300k of crypto because they had their seedphrases on their Evernote cloud account.
If you carry a substantial sum of Moons or crypto please backup your seedphrase on paper and no where near the internet.
