What's Hot: Ghost offers two kinds of backup: supported-disc based and file based.
Disc based takes an image of the entire disc and file based allows you to choose files and folder to add to the backup.
Disc based can fill up space quickly so Ghost allows you to define a base backup and then future backups just add in the differences.
Backups can be scheduled based on day, time, and events, such as log in/out, run a certain application, or install an application.
Disc-based backups can be compressed in different levels--it appears that file-based backups are compressed but there is no choice of compression level.
Backups can be converted to VMWare discs; this is useful if you use that application.
Ghost can notify you of errors or backup status in several different ways, including via email or SNMP--useful for network administrators.
Backups can be controlled on other network computers from a single instance of Ghost.
What's Not: There is no option in Ghost to back up files without being converted to their backup format. You always need Ghost to restore the files.
I use Microsoft Virtual PC in preference to VMWare, so an option to convert to those disc formats would be useful to me.
