1. Backblaze Hard Drive Test
2. Backblaze Vs Carbonite

• The transfer rates up to BackBlaze vary, but I think it's gonna take quite some time to get all that up. Like potentially a month or two, no matter what your upstream. The best rates I've seen to BackBlaze are usually around 25mbps. There is the 'mail hard drives in to seed' option. I'd also have some concerns if you ever had to download ALL of it.
• The response I’m seeing from BackBlaze does not align with the severity of the issue. From my perspective, it looks as if BackBlaze is providing information about my data to a third party. That is a major concern. BackBlaze response of “We’ve looked into and verified the issue and have pushed out a fix.” is not a confidence inspiring.
• CrashPlan and Backblaze aren’t particularly hard to use, but as far as interfaces go, Backblaze is a bit more intuitive. When you launch Backblaze, you don’t need to tweak any settings.

Backblaze focuses on ease of use. It is backup for people who need backup and 'pretty good security' and who aren't computer professionals. It is not a perfect choice for all users on earth. Take our default security model - it is about as secure as a Facebook account.

Brian from Backblaze here. To be clear, there are two levels of security/encryption at Backblaze:

1) The friendliest way we could design for people to restore their files was to allow customers to sign into a website with a username/password and recover one or more files. This is the default situation.

2) You can optionally turn on a 'private encryption key' but if you do that, understand you MUST write down that key because if you lose it, you can never recover it, and Backblaze (nor any government organization) will EVER be able to recover your files. NEVER. LOSE THAT PASSWORD AND THEY ARE GONE GONE GONE!

In the case of #2, as long as you don't need to recover from a crash, you don't enter your private encryption key and nobody will ever have access to your files, period. However, if you lose a file, you have to sign into the Backblaze website and provide your passphrase which is ONLY STORED IN RAM for a few seconds and your file is decrypted. Yes, you are now in a 'vulnerable state' until you download then 'delete' the restore at which point you are back to a secure state.

If you are even more worried about the privacy of your data, we highly recommend you encrypt it EVEN BEFORE BACKBLAZE READS IT on your laptop! Use TrueCrypt. Backblaze backs up the TrueCrypt encrypted bundle having no idea at all what is in it (thank goodness) and you restore the TrueCrypted bundle to yourself later.
