Yes it is true, both Mozy and Carbonite specifically throttle uploads,
and they say so on their product pages. I've never heard of a telco
throttling transfer rates either up or down, beyond the actual speed of
the connection. Backblaze, unlike the others, asserts the backup speed
is limited only by your internet connection.
I don't know who you're getting your cable service from. My only option
is Comcast and they advertise download rates of 15mbps (half the speed I
get from DSL) and upload speeds of 3mbps (the same I get), but those
speeds aren't actual ongoing rates but the result of "PowerBoost" and
only apply to very small transfers. Their business service would give me
22/5, presumably actual speeds, but at a considerable increase in my
current cost. It seems they've come a long way in the last few years,
but they certainly aren't dramatically better than DSL. It's also
Comcast, a company that is obviously not a reliable resource for anyone
that uses large volumes of data based on their recent history.
You are correct that restore speeds will be much higher, none of the
three services indicate they put any limitation on that.
