Hello,
I would like to backup a partition (/dev/hdaX, not the file system) to a DVD. The partition is too large to fit on a single DVD, but with compression (gzip) it fits. It is then still larger than 2GB (close to 4GB).
I cannot use temporary disk space to store the partition before burning it.
I would like to use DVD+RW media on a Plextor PX-716A.
It is perfectly fine if I can get at the data from Linux only; compatibility to some other OS is not an issue.
Now I'm at a loss. I tried using the streaming mode of growisofs/mkisofs; that works insofar as I don't get error messages, but the file on the DVD cannot be read later (as it is > 2 GB, I assume). I played around with dvdrecord, but didn't get far (piping stuff into dvdrecord, it didn't seem able to work with media that had already been written to).
Can I use growisofs to supply my own stream of data without an ISO FS being created? I.e., can I somehow access the "builtin_dd" of growisofs, which seems perfectly capable to work with my combination of drive and media? Or is there some other way?
Thanks in advance, Ekkehard
