How to burn a file over 4Go size on Linux k3b
Friday, September 14th, 2007k3b is just a front-end to growisofs, mkisofs, cdrecord, and other assorted programs, so it shouldn’t have any limitations of its own, but just reflect those of the programs it calls.
It appears that growisofs in turn calls mkisofs, which is what is complaining about the file being too large. Googling appears to confirm that this is a internal limit of mkisofs.
So the trick is to split the file in two, which first doesn’t sound very interesting, unless you have the good tool !
The solution: Splitpipe !
To create backups:
tar c /home | splitpipe -s dvd -o ‘growisofs -Z /dev/dvd=/dev/stdin’
To restore backups:
joinpipe /dev/dvd | tar xz
It features checksums, making sure that the dvds are read in correct order, and other usefull features.
But it can also be used to backup the entire /home on multiple DVDs.
