Adding new checksum files may or may not be a big deal. If the snapshot hosts have enough memory to keep the files in cache a bit longer, so they don't need to be read back from disk, running new checksums may be very fast.

In order to get the SHA-256 for the timestamp, I need to download each file and compute the hash.
I understand it's suboptimal, but if you're in a rush you can also use Toolforge and create a tool, a bit like https://dump-torrents.toolforge.org/ , to run sha256sum on the appropriate files (which are mounted even on the bastion host). I/O tends to be rather slow but may still be faster than your networking.
