It's not free, and you'd have to learn a wee bit of linux CLI, but you could use PartEd magic. It includes TrueCrypt (unless it was recently removed) and ntfsclone. ntfsclone is a CLI utility that could be used to copy data from one mounted TrueCrypt volume to another (or to create a backup image from one mounted TrueCrypt volume on another). ntfsclone copies an entire ntfs volume's data (instead of copying the entire volume bit-for-bit). Presumably Acronis did that as well. If you were previously copying bit-for-bit, then you might not need to learn the CLI, because you could use the GUI disk utility to copy the data after you mounted the TrueCrypt volumes. This wouldn't include the boot partition, though, so I'm not sure it would be good enough for an OS backup (vs using CLI to copy the MBR) because I don't have a lot of recovery experience with TrueCrypt system volumes. All of this could be done for free with a bit more Linux experience and a bit more work, because you could boot some other live linux and get whatever utilities you need running in that.
