I am looking for inexpensive backup software that will do true incremental backups of really large files. I am running Windows 7 64-bit.
I use a lot of virtual machines which, as you know, are virtual incarnations of whole hard disks which are, of course, very large.
I also have a 2 gigabyte outlook.pst file.
I want software that can do a full backup of these files once and then backup only the parts of the files that change after that without degradation of the files.
Can you recommend any software. I googled and found this sofware which seems to promise what I want. Or maybe all modern backup packages (like syncback) will do this.
In my experience and incremental backup backs up the changed files not the change portion of the file. But I also know that incremental backups of partial files are possible because programs like Dropbox and Jungle Disk do this. (I am not inquiring about internet backups...I already do that but only with my key files. There is too much data to do that with virtual drives.)
Any insight will be appreciated. What do you guys recommend to your friends and customers.
