Online storage and raw images getting compressed

4 years 4 months ago #668670 by Kate Stailey
I have my photos backed up on a couple different local hard drives, and would like to get things backed up on some sort of online storage.  I've heard these services tend to compress files.  So when RAW files are compressed, are there changes in my files from the compression?

Data compression is not specifically files compression. The
compression applied is light as the whole folder is compres-
sed and not the individual files it contains.

If necessary, you may retrieve and uncompress unaltered files.

Light is free… capturing it is not!

OK, that is good to know.  Thank you for the clarity.

ADDENDUM

BTW, Raw files can not — in whatever way — be modified
after they left the buffer for the card in your camera.

You may feel totally safe, Kate! :P

I save raw files in the cloud or on HDs...only.

Why so serious?

Any compression that occurs on the server end of things should be of no consequence to you. Your files, being backed up, should be restored exactly. You should never see a change.

It's not like a webserver re-compressing JPGs. Not at all.

Expand the idea: you can back up all kinds of files: text, .doc, tax returns, PDFs, whatever. Wouldn't you expect them to be precisely as they were on your system? No different for images (or video for that matter).

If anything happens on the service end, it will be transparent to you. Your only concern is reliability and availability.
