And, what good are they?
here's a related question:
Once you have found them, what good are they?
They are fine products for Windows, but they do not understand either the Mac GPT partitioning scheme or the Mac HFS file system. what this means is that backups using True Image can only be made from within the VM running windows. the VM has to be working to make or restore a True Image backup, as far as I can tell. Why would one make or use such a backup given the ability to clone or snapshot a VM that already exists in Parallels? Also, True Image Home 11 is, in my experience, a bit buggy, and has been replaced by a new version, True Image Home 2009,
Similarly, Acronis Disk Director suite can not deal with Macintosh partitions (which use GPT) or the Macintosh file system. The program also has to used from windows, from within a functioning windows VM, and will only repartition virtual disks in the VM itself. It may be useful if one wants to expand the VM disk image and then expand a single windows partition to take advantage of the increased virtual disk space in the form of a larger virtual C: drive, but there is little else one can do with Disk Director on a Mac.
I'd love to see Parallels bundle Mac compatible tools, rather than Acronis
