RE: [H] Linux imaging
Depending on the imaging solution. DriveImage or whatever before Symantec used to do sector cloning by default. Ghost has almost always done file ghosting except when explicitly given the sector cloning flag. To do real sector cloning is a pretty huge and inefficient process. Its only good for forensics. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Harry McGregor Sent: Tuesday, April 18, 2006 12:47 PM To: The Hardware List Subject: Re: [H] Linux imaging Ben Ruset wrote: > Tar is taking files out of a compressed (well, if it's gzipped) > archive and recreating them on your system. :) > Imaging is doing a sector by sector copy, archival, compression, and > sector by sector restore on another machine. Not necessarily. Ghost under Fat32/NTFS does not do sector copy, it does file copy, and recreation. > Now, if you were dd'ing disks, I'd say you were imaging.

Re: [H] Linux imaging
Tar is taking files out of a compressed (well, if it's gzipped) archive and recreating them on your system. Imaging is doing a sector by sector copy, archival, compression, and sector by sector restore on another machine. Now, if you were dd'ing disks, I'd say you were imaging. BTW, we do tar restores of our Linux boxen here. :)

Interesting, but this is a dual boot box. Win2K and Suse-10. So it would be easy for me to use a program like Ghost. I have Drive Image 7.0 but I don't trust it with Linux. Back in version 5 or 6 I discovered that while DI would back up Linux it couldn't restore it properly, it wouldn't boot. Maybe version 7 is better? But if Ghost works I probably have a copy on a old System works disk. Christopher Fisk -- BOFH Excuse #385: Dyslexics retyping hosts file on servers

Partimage can deal with ext[23]fs, Reiser3, JFS, and XFS partitions. www.partimage.org is the site.
