Hi Richard,

Yes, that was a sweeping statement, meant to raise the awareness of 
those who use the internet (Cloud) which, includes the vast majority of 
us and our offspring. The fact is that most, if not all, who rent server 
space use some kind of data compression to save space (and $). Most will 
not tell what they use. You can buy data compression/encryption software 
that will return bit-for-bit. Some are OK with the concept, some are 
not. One possibility is to use a code (There are many variants) in the 
metadata of the files you plan to store to insure that you get the same 
files back.

Here is another sweeping statement:

I try and avoid those that do data tracking. ALL OF THEM (can you say 
VPN?) and, I plan to disengage completely from all social media by the 
first of the year because of data tracking regardless of your settings 
(preferences). I do however, use Dropbox. At least, temporarily. I plan 
to dump them as soon as my paid service runs out due to slow upload 
speeds. I have a 70Mbps service but Dropbox is very slow to upload, 
about a third, or less, of what I have available (Can you say 
/throttling/?). I don't use Backblaze because I clone my boot drives 
instead of doing backups.

Apologies to the list for being way off topic.

Da Ole' curmudgeon,
