Note: I use Google Cloud for my staking wallet and backups but the script works regardless of what you use; if you have timelocked coins, you will have to keep your wallet.dat file secure for a long, long time: it's crucial to maintain secure the staking instance as well as the storage..
VRSC Wallet and Data location on Linux: ~/.komodo/VRSC
If you use GCloud:
- create a new directory where we'll upload the backups (ie: mkdir /home/user/backup)
- create a storage bucket via GCloud console (ie bucket_verus)
- mount the bucket on your local machine (syntax is: gcsfuse ; ie gcsfuse bucket_verus /home/user/backup)
The script can be crontab scheduled to run daily or you can run it manually; if you schedule it, you have to hardcode the encryption passphrase; otherwise you can input it manually each time. You will have to install gnupg2 to encrypt (sudo apt-get install gnupg2 gnupg-agent). As always: be sure to fully understand what the script does and why I left some echos to demonstration/test purposes, you can sefely remove all of them.
