Backup restore doesn't work about docker_base_images

[danimbrogno]

One other issue, if you choose not to encrypt your backup, the backup works fine but the restore fails because it attempts to decrypt a tar that is not encrypted. I fixed this by changing lines 172-177

 export RESTORE_FILE_DECRYPTED="decrypted.tar.xz"
  if [[ -s "$RESTORE_FILE" ]]; then
    log "Decrypt ${RESTORE_FILE}"
    export GPG_TTY=/dev/console
    gpg --batch --output "$RESTORE_FILE_DECRYPTED" --decrypt "$RESTORE_FILE"
  fi

to

export RESTORE_FILE_DECRYPTED=$RESTORE_FILE
  if [[ -n "$GPG_RECIPIENT" ]] && [[ -s "$RESTORE_FILE" ]]; then
    export RESTORE_FILE_DECRYPTED="decrypted.tar.xz"
    log "Decrypt ${RESTORE_FILE}"
    export GPG_TTY=/dev/console
    gpg --batch --output "$RESTORE_FILE_DECRYPTED" --decrypt "$RESTORE_FILE"
  fi

I'm not super familiar with bash scripting and haven't tested whether an encrypted backup restore works with this modified code.

I can submit a PR if so desired.

Thanks for reporting this. I will fix it by the end of this week.

Hi @danimbrogno, I have fixed the restore function and also did a major refactor of the code in the entrypoint, so that it's cleaner and easier to debug. c871699 should take care if this. Check the examples I added in the README. Some more testing would be appreciated, let me know if it works okay or not.
