BrianW from Backblaze here. That is a little high, but is plausible in some installations. When running Backblaze on a laptop, you will notice a couple different processes running. "bzserv" should always be very very small, it doesn't do much. When you see "bztransmit", that is the process that reads your files from disk, encrypts them in RAM, and transmits them to the Backblaze datacenter. It tends to be about 30 MBytes of executable code, plus up to another 30 MBytes of the file being encrypted in RAM and transmitted. So most customers will see bztransmit bounce around at 60 MBytes RAM.

HOWEVER, there are short moments when bztransmit must read a list of files into RAM, and it can reach larger sizes like 240 MBytes. bztransmit does the deduplication, which means it must store one SHA-1 of every file it has transmitted from your computer to our datacenter. If you have a lot of files that have been transmitted (over 1 million files is "a lot") then Backblaze might reach 200 MBytes in size.
