I am currently/always looking for better user backups for our employees. We have tried multiple online solutions before (Carbonite, Mozy) and we've tried multiple local backups (rsync to a central server, Maxtor Onetouch+, Acronis Truebackup, etc)
Here are the questions I have when hitting your site. They're just my quick overview thoughts, but they might be of help-
How much does it cost? Do you charge per user, or per GB?
"Every Hybir Backup is the equivalent of a Full Backup at the speed of an incremental. " Do you do block level backups, or file level? Ie, is this akin to Ghost, or more akin to rsync?
"Hybir Backup leverages all the data it has ever backed up for everyone. "
This makes it seem like you do a md5 on the file, and store by that, rather than by the file itself. Do you preserve permissions, etc?
Also- What do you do if there is 1M of changes in a 100G file?
How do you handle updates to the client? Do they roll out automatically, or do users need to download and install them?
Is it possible to have one master account have access to all sub accounts? I'd rather not have them all have the same username+password, so that users can't download eachother's files.. All the same, I don't want to have to keep a spreadsheet with XXX passwords.
"Security a bank would envy" SSL security is great for it getting to you. I'm not worried about that. What about isolation from other customers? Can we encrypt our backups with a private key, so that you compare block-changes against OUR files, but not against others in your datacenter?
"Full Backup" You're backing up the MBR, etc. Is there a way to restore this if it's broken (a boot cd or similar?). If not, what good is it? (Honest question.)
"We may use your PII to contact you in connection with offers, responses to your inquiries, information on new services and features, and in connection with administering and offering our services."
I'd really like to see the privacy policy clarified with regards to the difference between Personal Information (Our name, etc), and the data we upload.
"The Software may be installed and used solely on one standalone, un-networked desktop or laptop computer identified by Customer when subscribing to the Services, and the Services may be used solely for such standalone computer."
This terms of use sounds like it's written for a commercial program, not a service - We want to install on many computers, that's the point ;)
"3.3 Hybir retains the right, but not the obligation, to retain copies of obsolete or deleted files, subject solely to its obligations of confidentiality hereunder."
This makes me nervous, FWIW.
Overall, it looks like a good product, in a very, very crowded market.
