[gentoo-user] Multi-DVD backup

[JimD]

Does anyone know of an app/script for doing a multi-DVD backup of my ~/? 
  My ~/ is 10GB so I will need something that could do a little 
compression and create as many DVD iso images as needed.

I was thinking of just tar.gzing my ~/ and then splitting that file to 
sizes to fit on a DVD and then make the ISO.  I was hoping for a 
script/app that is tested since I don't want to lose my data and I have 
to format my computer soon.

Thanks,

Jim

look at freshmeat.net for scdbackup.  it can be called with  
sdvdbackup and will span dvds.  I back up my mail server totally to 4  
dvds.  you can tell it what filesystems to backup, or directories.   
it figures it all out for you.  be warned that growisofs is a prereq  
for it.

Do you do the ISO or afio backup?  If you do the ISO backup, do your 
file permissions get hosed?  I see that the utility puts a script to 
restore directory permissions on the last CD/DVD in the set, however it 
didn't mention anything about file permissions.

I can't remember which I do.  I'm not terribly concerned about  
permissions, as for the most part, i'm concerned with being able to  
restore mostly /home and /var/spool/mail.  the rest is just in case,  
as it were.

sync2cd

Doesn't do compression, but stores your files as-is, spanning multiple
DVDs. Well, actually it doesn't do the storing, but generates lists of
files to be fed to mkisofs or growisofs. Restores permissions,
ownership, etc.

  http://www.calins.ch/software/sync2cd.html

It's in portage. The latest version is in unstable (has been for a few
months) but works ok.
