I have two MacBooks - a Pro (10.6.8), which I keep at home and on which I keep my most important files; and an Air (10.7.5), with which I travel and on which I generally do not keep sensitive files, for security reasons. Also, there are certain files which exist on both computers, but in somewhat different forms, with different organizational structures. Currently, I am using Mozy for the Pro, but not for the Air, because I am concerned about interaction between the two. I know that I can choose which files to back up, but is there any way I can specify DIFFERENT backup choices for the two different computers? If I back up both computers on a single account and have to use the same file selection for both, is there any way to keep non-identical files SEPARATE for each computer? I want to use storage space, and money, efficiently; I don't see the need to have (and pay for) two separate accounts, to back up the entire contents of each computer separately when they are at least 50% identical - but I very much don't want a backup from one computer to overwrite the backup from the other and force me to choose between a single file set. I made them different for a reason, and I want to keep them that way.
I realize that I am behind the times - everything is supposed to be floating together on the cloud, where life is beautiful and everyone is happy (until your identity is stolen) - but there is no technological reason why one can not have separate sets of data on the cloud, as one has in real life.
I'm not sure but maybe you could have different drive names on the files and be able to store them that way. The files would have different names and Mozy should think they were different files. They would not compare them to see if they were the same.
Might be worth looking into.
Here is a quick rundown on de-duplication. If you were to go and buy that latest tune from AC/DC from iTunes, and add it to your backup set, it would be backed up to our end. If someone else were to purchase that same exact song from iTunes and add it to their backup set, we would simply check to see if we already had that file and then rather than back it up, we would point to that file for the second person. If 100,000 people were to purchase that same tune, we would back it up once and point the other 99,999 people to that file instead of backing it up 100,000 times. So, you would simply need to see if the file is the same between the machines. If the files are different, even if they are named the same, we would simply see them as different files and each would be backed up.
Hope this is helpful..
A most helpful answer, and an ingenious solution. If I add a second computer to my account, though:
(1) Do I have the option of manually specifying different backup selections for the two different devices? For instance, can I back up the entire MacBook Pro but only selected files from the MacBook Air? (I know - why would anybody want to do that? Because very similar files on the two computers may still not be perfectly identical, and I'm not sure I need to make two whole copies, particularly with my Godawfully slow internet connection - I can just back up the one I prefer. Also, that could use up a lot of storage space.)
(2) If I want to restore files to one of the computers, and I have backed up both different versions to Mozy, is there a way to tell which version is which - particularly if they have the same name? Yes, I can add some kind of suffix - [File]1 or [File]* or something - but that means relabeling every file in one of the computers.
(3) There is one (large) existing file, differently organized on the two computers, which I might actually want to Sync between the two; I gather that this would also address the duplicate storage issue, and save space. If I put the file into Sync from both computers, will one version overwrite the other? (I have encountered this problem in another area - if I have all my iTunes songs on one computer, and I accidentally sync my iPod to the other computer, everything on the iPod is erased and I have to reload it all.) Or would both versions end up stored separately on Sync, being non-identical? Would I need to delete the entire file from one computer, copy my preferred version to that computer from the other computer (via a flash drive - with my slow connection, much faster than having Mozy sync a large file) - and then also add the preferred version to Sync, so that future changes will automatically go onto both computers?
(4) Not that I'm complaining, but - if you only store the song once, and then just add pointers for everyone else who has it, why is the entire file size counted in calculating how much storage space I have left? (Or is it?)
