How to write a CD-R Data Set - with 1.3 Gb disk data set?
Is it possible to backup/write a directory whose size is around 1.3 Gb to 2 CD-R's without having to split the data into 2 separate components? In other words much like the way 'DOS backup' used to write to 'multiple floppies'. -- Best regards, Des Aubery...

That would be nice to have - or a pcbackup even better :-) Well, you can create a compressed cdrom (zisofs) - depending on your data, it might fit on a single CD. Or, you need to create a tar from the directory, and split the file in two. -- Cheers, Carlos Robinson

Would tar -L/--tape-length=N work? man tar says it changes tapes after writing N*1024 bytes. -- Vic Ayres

Oops, having delved a bit more, I should have advised info tar not man tar. (Not an info fan.) -- Vic Ayres

I would have to read the manual, because I don't use tar too much. It has lot of options, and some of them are for splitting. In any case, I don't like tar for backups: at least when compressed (.tgz), if there is a media error, you may loose all the files. -- Cheers, Carlos Robinson
