Compression rate Ghost 12
May 18th, 2007 at 12:46am
 
I was wondering how much Norton Ghost compresses the data?
Lets say i want to back up my c: drive with a size of about 30gb, and i want to backup to dvd,
how many dvd's does that roughly take?

Does it compress the data alot or am i looking for about 8 dvd's?

Thank you in advance

scar,

It depends on what sort of files you have on the C: drive. Let's say your C: drive has 30 GB of used space and 60 GB of free space. The used space is all that counts. If you use High compression and your 30 GB consists mainly of software installations then you could expect an image size of 15 GB. But if you have a lot of non compressible files, such as video and music files, then the image size will be much larger.

Do you have your HD partitioned?

Let's talk about the problems with DVDs later.

Well the other day i reinstalled my system so everything that's on the drive are the OS and a few programs..(so basically the bare essentials i need) all in all between 25 & 30 gb of used space.

I only have 1 hd and it's not partioned.

I mainly want to make an image because it's so tedious to reinstall windows and all the following updates, it's not like i want to make it a regular backup type of thing (i burn everything i download/create on an almost daily basis so i'm pretty secure there).

scar, when I install WinXP and a few programs, the used space is around 3 GB. How did you get to 30 GB?

just did a recheck and make that about 11gb total (i forgot to excluded a folder with media files, approx 15 gigs).

According to Directory Opus:
Documents & Settings 395mb
Program Files 4.53GB
Windows 5.47GB
MSOCache 543mb

so would that fit on one dvd or maybe a DL?

edit: btw i would remove that Media folder before i make the image

11 GB. That's more like it. One advantage of partitions is that you can have your data (music, video, photos etc) in a non C: partition and your OS recovery points (images) are relatively small. I don't image non OS partitions as I use data backup software. Much more efficient.

Your recovery point would likely take two DVDs (or one DL). If you use conventional discs, Ghost will tell you when to insert the second disc. Make sure you use High compression when writing to DVDs.

Yes, remove that media folder prior to imaging.

Ok thank you for your time, a couple of dvd's sounds far more appealing then wasting a couple of days reinstalling xp the "normal" way =]

best regards,
scar.

You will "never" have to waste time installing WinXP again.

Are you planning to get a second HD or an external HD? Imaging to a HD is faster and more reliable than imaging to DVDs.

Let us know how long it takes to write the image to the DVDs.
