Backup of encrypted private key on uncontrolled disks

Hi all,

My private key is encrypted with a very strong passphrase (10 word diceware [1], not written down, 129 bits of entropy). Given that, is it safe to back it up on disks I don't control, such as a private S3 bucket or a VPS? My intuition says yes, but I've learned to never trust my intuition when it comes to security.
