Really? Why do I have to compress the target disk to compress the
data when the program should have an option for it internally without
relying on the compression functions of the operating system?
If the hardware itself support compression then NT Backup will turn it
on. Hard drives do not have hardware-based compression so it can't be
turned on. NT Backup itself won't do compression (unless you get the
uncrippled version).
No it won't, and I can prove it. Show me where in WinXP Pro SP2 that
it does images.
He probably meant it will create a rescue backup set which is a full
backup and some boot floppies. This is the ASR (Automated System
Recovery) Wizard. It is a *logical* backup because the files must be
read through the file system and tables of the running operating system.
Even some "drive image" programs are really just logical backup
programs. Ghost does a logical drive "image" by default unless you use
the /IA parameter to force it into physical mode (where it reads
sectors). On a restore where EFS was used, the EFS certificate won't be
in place so the restore will fail (Symantec's answer is to remove EFS
before saving the logical image, or save a physical image instead).
[Note that this applies only to the OLD version of Ghost and not the
re-branded version of DriveImage after Symantec bought Powerquest.] Some
other "imaging" products also default to make a logical image but might
be configurable to save a physical image.
Breaking the backup set into smaller chunks is not exactly a
requirement, but media spanning should be an option in any backup
software worth it's salt, which ntbackup.exe isn't.
The only spanning that the NT Backup program will handle is across tape
media. It will not span across removable media, like CD-Rs, DVD-Rs, or
hard disks. That's why I got the uncrippled version.
No they aren't. Backup sets from Win98 will not restore on WinXP. I
know, I've tried it. It doesn't work. And there is no garuntee that
Microsoft will not break backwards compatibility in the future again.
Yeah, there is no way future compatibility can be guaranteed. At most,
you only get *some* backward compatibility. But that's true of whatever
method of backup you use whether it be logical backup software, physical
drive images, or just copying files under some file system which may
become dated and no longer supported.
