    Hi all, i'm not sure if you faced the same problem but i have the same question for some time, especially when i start dealing with large files.

    So the problem is this :

    All software programs when they do incremental file backup they store the files that were changed from the last full backup BUT if you have 1 large file that was modified they will not go and store the exact modifications of the file but store it again as a whole file.
    This is a serious issue if this file is several GB

    Even for Acronis True Image 2011 (i don't know for 2012), Acronis employees admitted that if someone wants to do file storage that way he should select partition backup and exclude the directories he's not interested to store.

    What i seek is a windows software that will not store the whole file but only the fractions of the file that were changed since the full backup was taken.

    Any ideas or straight leads to a software ?

    Are you looking at remote storage as Dropbox and jungledisk do block level updates only and just don't upload the whole file again after each change.

    There is no option to do online backups because for example two mounted VMware disks/files are 32GB each. Even after compressing them both are about 50GB. I search for a local solution. Each file (disk for VMware) is changed each and every time but i don't want either to start excluding everything or fill my 1.5TB in no time with "incremental" file backups
