If Yes to all three, then there is a safe way to store the password (using Windows encryption based on your account password).
Linux experts may know a safe way if Yes to the first 2.
If No to one or both of the first two, then there really is no safe way to enter or store any information on the computer, an usb stick will also be unsafe. Still configuration password is better than nothing if the other users aren't somewhat determined to get access.
hmmm, the OP is running on a winbox.
so about 1. any monkey including jojo, and some humans, can convert a standard account into an admin account with a quick reboot.
so 1+2+3 would need the fourth item
0. bitlocker the c: drive.
and then have to work around 4+5+6+7...1000
the easy workaround, given that rclone is a portable app, is to store rclone and config file on a usb key.
better yet, a usb key using bitlocker to go.
plug in the usb key, type in the bitlocker password, and run rclone from that.
The whole question is:
My fear is that someone will edit the backup script and throw other files in the cloud, deleting what is already there and I will lose my backup.
Is there a way for rclone not to erase what's in the cloud?
Nope as I don't have access to Google anymore as all my accounts are closed. I'd assume it's possible but not sure offhand.
If you aren't sure how to do it the IAM Google Cloud Suite Admin, you can also select read-only for the rclone.conf, but that's really just for show.
I'd say you are starting with a flawed premise as if it's a shared computer that you can't control, the data on it would be considered comprised already so we call that putting lipstick on a pig as you can't even be sure your data is in good shape.
