1. I use Acronis True Image because of previous experiences with NT Backup that didn't work out. But, since using Acronis I haven't taken the time to try any other solutions (there are many out there - some of which are freeware). I'm also a beta tester for Acronis - so I haven't had to purchase any software from them since I originally bought Acronis True Image v7.
2. I use it all the time for imaging. The images that it creates are too bulky for routine backups. FYI - here's a link to the strategy that I use at my wife's office:
http://www.bleepingcomputer.com/forums/ind...st&p=357653I don't use it for backups because of the size issues. I use SyncBackSE for my backups (although I hear that Cobian Backup is just as good, if not better). It's free and I can schedule it to run automatically. It emails me reports and can even FTP the backup files to another computer.
3. An image is an exact copy of the drive that you're imaging - that's everything! It also keeps track of where on the disk each item is - so that your boot sector, etc is put back into the right place.
4. I don't like to run Acronis from within Windows (no problems, just personal preference). I do this because I don't want to take the chance of anything conflicting with the making of the image.
The Acronis rescue CD allows you to boot to an environment that allows Acronis to run without having to load Windows. This leaves the boot drive idle - so that no other programs are accessing it. From there you can make images or restore images.
This may be limited in some PC's by the availability of the USB drivers (my Toshiba laptop is an example). Since it's a laptop I don't have a second drive - so I have to use a USB drive to backup the data. But the Toshiba's are very proprietary - and Acronis doesn't like to run in regular mode from the rescue CD - so I have to run Acronis in it's own "Safe Mode" (not the Windows Safe Mode). And when it runs in it's Safe Mode, it can't access USB drives . Grrrr!!! The workaround is to establish an Acronis Secure Zone on the laptop's hard drive and make images to there.
5) Resident applications don't seem to cause any problems (I've run it from within Windows a few times) - so I wouldn't be concerned about that. Just as a precaution I'd stop any applications from running while making the image. As I said earlier, I prefer to run it from the Acronis Recovery CD rather than in Windows.
6) I fit 6 or 7 images onto a 120 gB external USB drive - so I'd suspect that you could fit at least 4. This depends on how packed the hard drives are and how much compression you use when making the images.
7) Acronis will make (if you ask it to) a partition called the Acronis Secure Zone. It stores images there to keep them safe. There are other utilities available that will partition your hard drive into 2 or more drives. In other words, on one physical hard drive you can have multiple drives (C:, D:, E:, etc).
8) Please remember that the Toshiba software/hardware is a bit too proprietary for Acronis True Image. You can create images from within Windows and put them on the USB drive - but you won't be able to access the USB drive from the Acronis Recovery CD. That's why I suggest using the Acronis Secure Zone on a Toshiba laptop.
Finally what I like most about the Acronis software is that it's easy to use. Install it and you're ready to image your drive. You can learn a lot about it by just using it (that's how I've figured it out - never have RTFM!)
