just discovered sugar sync, looks good
It is interesting but more expensive than SafeCopy. Backblaze is more configurable than I thought, but the one downsize for me is that you need a separate account for each machine you want backed up. I am not clear as to whether running a VM with XP and / or Ubuntu is considered 1 machine or 3 machines. I will ask when I get their next reply to my last question set.
I still like iDrive, but until they encrypt the Mac files, I would not use it. I also like the idea of backing or accessing from a mobile device like the iPhone.
Edit 5/16
I signed up for SafeCopy and probably made a big mistake. I initially wanted to backup a selection of important documents including a backup of my Thunderbird email account. The total size of the files was 167 mb. It took 3.5 hours to backup and seemed to stall on the TBird backup file. It would not continue to backup the smaller files until I clicked on the TBird file. After backing up several other files in addition to the TBird file, it stopped backing up the other files. At this rate, it will take a year to back up the files I want. In addition, I keep getting error messages. I have sent this all to tech support and they are working on it.
I then did what I should have done before. I downloaded them all and tried them out or requested the free accounts.
iDrive was the fastest and easiest to do what I want, but as mentioned they require an account / license for each machine so that adds up for an iMac, Macbook, and PC or Windows under a VM. It took 1 hour and 15 minutes for the identical backup.
Backblaze, while offering unlimited space will not let you select just the files you want backed up. You cannot exclude the C drive in Windows. You can however, go through a process of eliminating what you do not want to backup. I have all the files I want backed up on my second hard drive and do not need anything on the C drive so configuration is a bear... The pricing requires an account for each machine.
SugarSync is another product that can be configured easily for my purposes, however their pricing structure is much more expensive than others and I do not know if one account can be used for multiple machines.
Mozy allowed me to configure the way I wanted and completed the upload in 1:48, still much better than SafeCopy. However, they charge per machine so the cost of backing up several machines is expensive.
JungleDisk is just a front end ($2 per month plus the storage fees) so I eliminated this for now.
Carbonite is being tested now but is also a per computer price.
