How do you protect a remote backup from a compromised account? (lemmy.zip)

Let's say you have access to a remote machine and use it to copy backups occasionally, eg with rsync. Your local machine has credentials stored that allow write access on the remote machine, however if the local account was compromised that could also allow access to the remote machine and the data stored there.

How can you grant access to an account to write remotely, but also protect the data from this account? One possibility could be to change the permissions on the data after it is copied to prevent deletion/interference, although I'm just making this up. Is there a standard practise for this?

Yes that seems like one way to go. Although I am using rsync so maybe keeping the files in place and changing owner could be an option
