Options for implementing cryptoprotection with remote access on a flash drive?

Question

Remote access

Are there options for storing personal files in a protected form on an external medium, taking into account the following wishes:
1) all personal data - in the crypto section;
2) out of protection - only the "Read me" file with coordinates and a request to return for a fee;
3) in the presence of a stable Internet channel - backing up personal data to a private cloud / to your home computer, etc.;
4) when connecting to trusted computers - creating a local copy of the crypto partition on the local disk?
