hi im trying to back up my system to do a fresh install. I have a directory named music where i ripped some of my cds. It is 2.2 gigs so i have to break it up to burn to cds as data files. I was wondering if there was any command i could use in a shell script that would be able to go thru that directory and splitting it up into directorys that are 600-700 mb to fit on a cd. The directory is set up like this ~/music/artist/album/files. I'd like the structure of the resulting components to be like the music folder - so i wouldn't want all the mp3s to be just tossed into 3 seperate folders. Any replies are appreciated. thanks in advance.

I suggest:


That'll give you a nice compressed tarball for starters. MP3s don't squash down that much, though, but this does mean your hierarchy is nicely preserved for starters. Splitting this file into 700Mb (say) chunks is no problem; see the manpage for the split(1) command. Burn the chunks onto disks, then to restore your backup, copy the chunks back;


You can just cat them together because Unix won't mangle the contents when you do that. When you unpack the resulting tarball, your directory structure should be preserved. Hope this helps!

this is simpler
for the disk size discrimination you can use du and have a script that makes subdirectories up to some size and then do the tar on those directories
