We've been through this before, so I won't repeat the details. I do
image backups of servers, laptops, and desktops. (NAS boxes are a
problem). With USB 3.0, I can do about 3 MBytes/second. A typical
desktop, with 15 GBytes of bloat, will take maybe 10 minutes to backup
everything. The most common problem I have to deal with is a dead
hard disk drive. I shove in a new drive, restore the image backup in
about the same time it took to backup, and I'm back up with zero
reconfiguration (except sometimes using gparted to repartition the
drive). Cloud backups have been very useful for moving files around
and creating security problems. In my never humble opinion, cloud
storage is useless for backup due to the backup size and time
It is probably largely useless.
What is probably largely useless? An image backup?

But, supposing I have a camera
full of images and I am traveling. I can transfer them all
to my laptop; then I can upload them all to Amazon cloud
(might take overnight, it might have to be re-started a
few times). I then know they are backed up in
two separate places, and can therefore delete them from my camera.
I don't do much traveling but the few 3rd rate hotels that I've stayed
at usually have a simple cable or DSL connection. Upload speeds are
strictly limited. I'm told that more classy hotels have bandwidth
limiters on both up and download. Copying a large number of files
offsite is probably not going to be very effective.

But this scenario is much simpler than the general problem
of backing up drives and computers, which would probably fail
for some reason or another. The disconnects and failures
would interfere too much with your backup routines.
My backup routine is based on an image backup, which boots from a
CDROM, does not use the internet, and works very quickly (with USB
3.0). I have several customers that do much what you do when
traveling. They shoot uncompressed images and videos. I usually
partition the hard disk with a separate section for "archival" images
and videos. They get backed up separately. In all cases, they have
some kind of USB hard drive, onto which the images and videos are
copied nightly. When they get back home or office, they unload the
USB drive into the NAS box, burn a BluRay disk, or whatever. Oddly,
the procedure was contrived to deal with lost laptops, but it the USB
drives that seem to be disappearing.
From my warped perspective, the could backup schemes are nothing more
than yet another way to avoid doing a backup. To be totally
transparent about this, I really don't care if the customer loses
their pictures and videos. That's NOT my problem as I'm not being
paid to act as a private guardian of their photos. What I care about
is the time and effort necessary to restore their hard disk in the
event of a crash or failure (i.e. virus trashout or ransomware).
Backing up only the data, as in Dropbox, add a huge amount of work to
the recovery, which is the only reason I even mentioned an image
backup in this discussion.
