[BBLISA] Ghost 8.x and Grub/EXT2,3?

[Eddy Harvey]

Oddly enough, I have a little experience with that too.
But no success.

Even though Ghost 8.x supposedly supports ext3 and whatnot, as far as I can
tell it only supports it by doing a byte-for-byte image.  I have ghost 8.0
corporate.

If your goal is extensive rollout of many systems, which are all identical
to each other, with reasonably small hard disks (60G, 80G) then honestly
your best bet is probably dd.

If your goal is occasional backup/restore for the purposes of disaster
recovery, for systems that might have big disks, but might not use the
entire disk (say you use 60G in a 250G disk) then it's probably best to
follow what I wrote in the last email, and use dump.

....
I have one more thing to add to this.

Let's suppose you're in a situation now, where you want to backup a system,
but you haven't had the luxury of planning the whole 2G minimal installation
thing that I wrote a minute ago.  Let's suppose you would like to minimize
the downtime to perform backup, or you'd like to minimize the output file
size.

Here's another technique that's sometimes useful.

While your OS is running, you do this:
	dd if=/dev/zero of=zero.fill bs=1024k ; rm zero.fill
This will fill all unused disk space with infinitely-compressible-zeroes,
and then immediately release that disk space.
Then, you shutdown, and use dd | gzip
Since the unused space is infinitely compressible, you end up with the
smallest backup filesize, and it's a lot faster.  But you still have the
weakness of requiring the same size disk for restore.


Ok, that's enough for one night.   Ttyl

As a bit of a followup/tangent to my previous post, next to using dd for
imaging a Linux setup, what are people's experience with using Ghost 8.x
that 
reportedly supports Grub?   How about preservation of EXT2, EXT3, and LVM 
partitions/volumes?

Thanks.
