I've taken another approach to that. I split a volume of dirs/files into DVD-sized chunks. To avoid moving the original files, I work on a linked copy. So, if you have a "source/" data dir and a "temp/" working dir: mkdir temp/in cp -vrl source temp/in/ (remove 'v' for non-verbose) cd temp xsplit_dvd.py (set for 4GB DVD's) You'll find: temp/out/dvd_001/source temp/out/dvd_002/source temp/out/dvd_003/source etc... Just burn and delete them. The script can be found here: http://www.rikishi42.net/SkunkWorks/Junk/ PS: if you don't want to see "source" on your DVD's, just copy the contents rather then the dir: cp -vrl source/* temp/in/ -- There is an art, it says, or rather, a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. Douglas Adams

Thanks. As it happens I was splitting up a directory to put into Truecrypt (ISO9660 can't universally cope with files >2GB, but Truecrypt volumes are monolithic files). So I used 'dirsplit' to make suitably-sized chunks with hard links, and then copy those into the Truecrypt volume. I suppose I can use that for normal backups too. Theo |
