Hmm, good question. I don’t have a setup for that either, but I don’t think there is a built in function for that.
Your best bet is probably to find some tool that notifies you if new files get created in a directory, as AFAIK new snapshots are only created if they were successfully transferred.








Usually companies accept that you remove storage mediums before sending it in, as those might contain private data. And if that is ok, then there is no way for them to know that you installed Linux on those.
