Hi. I recently purchased Hard Disk Manager 15 Pro to enable me to backup my photos and videos to an external USB hard drive (USB 2 port). I keep all these on a second internal 4TB hard drive. About 4 days ago I started a backup using the "Backup to VD" option and it has been running ever since. It is still running now claiming it is 78% done and there are 17 hours 11 minutes to go. When I first started the backup I think it estimated about 11 hours. My computer is an Intel i7 running at 3.4 GHz, with 8 GB of RAM, running Windows 7 Home Premium, SP1.

Is it really supposed to take this long?

Do I need to invest in something a bit faster, like NAS storage?

Are there any settings I can change to make it go faster?

Would I be better off backing up using a file-by-file approach rather than backing up an entire partition (which I take it is what the "Backup to VD" option does)?

Any help or suggestions appreciated.
