File format

[Harrier]

I have been using True Image 8 for some time now and am quite
happy with its functioning (although I haven't tried to recover
using an image yet).

One thing still puzzles me about file formats. This may be due to
my lack of knowledge in this area, so bear with me.

I am assuming that the Acronis Image format (.tib file) is a
proprietary file type. How does it differ, if at all, from an
.ISO or .IMG file? Or are these image files something different
altogether?

I ask because of a warning message I receive from Nero Express
(see below) when I burn an image to DVD after having created an
Acronis image on a HD.

If the file size is greater than approx. 2GB, the UDF file system
is used. Am I to assume that an image file smaller than 2 GB would
be written to disk using the ISO9660 file system?

Are ISO, IMG, UDF solely related to CD/DVD?

It is my understanding that ISO & IMG are compressed file formats
containing info on file structure as well as file contents,
something similar to an Acronis Image.

" }-The TI file format is proprietary to Acronis. It's a compressed file if you selected compression during the setup for the image. It is a standard file and not limited to CDs or DVDs.

If you want to write TI images to DVD disks, the best thing is to split the backup at 1492MB (it's easy to remember 1492 because of Columbus :-). Three pieces will fit on a DVD disk with only a few MB wasted. This will avoid the warning message from Nero.

The ISO format is an uncompressed image of a CD-ROM disk. It has to be written to a CD to use it. It is unrelated to the TI image is format. I'm less familiar with the IMG files, but they are related to ISO files.
