My backup script split filesystem dumps to files with size of 4,37 GB (4 588 544 kB). It's just an optimal size to fill out DVDs. At this moment I have to burn them from windows via smb-link becuase I didn't manage to do this task from FreeBSD console due to 2GB/4GB filesize restrictions (growisofs). I'm using freeware CDBurnerXP to burn my backups (ISO9660/UDF/Joliet), and they mount without problems on my FreeBSD BOX, files are fully readable too. However, burning gigabytes of data via slow (about 3.5MB/s) SMB network is just annoing. Is there *any* way to burn DVDs with files>4GB from FreeBSD console? cheers! -- Bartosz Stec

OK, that's *some* way, but to be clear - I want to avoid preparing ISO images too ;) -- Bartosz Stec
Hi, Bartosz Stec wrote:> [...] Is there *any* way to > burn DVDs with files>4GB from FreeBSD console?I succesfully used growisofs for exactly this task ;-) What I did is (for DL-DVDs): # growisofs -dvd-compat -Z /dev/cd0=$file.iso -speed=2 I had to limit the speed, else it wouldn't do anything. If I burn "normal" DVDs I don't need the speed limit. HTH, Philipp

I have burned 4.3GB DVDs several times. -- David Kelly N4HHE, dkelly@HiWAAY.net =======================================================================Whom computers would destroy, they must first drive mad.

I'm using freeware CDBurnerXP to burn my backupsWhat "limitations" are you thinking of? Growisofs is based on mkisofs which is part of cdrtools. Mkisofs supports large files since a long time (~ 8 years).>I never had a problem writing huge files. But I did have a problem >subsequently reading it with Windows XP.

You must use UDF to burn files of greater size. >mkisofs(8) seems to support this, if only in alpha/hybrid stage:The ISO-9660 standard is limited to 8 TB for the max. filesystem size as well as for the size of a single file. Mkisofs supports single files up to 4 GB since ~ Y2000 and it suppports files up to 8 TB since 2 years.>growisofs will write 3 files to the DVD just as easily as one.

There is however a big social problem with the anti-social habbit and propaganda from Debian. Fortunately, cdrtools is not related to Debian, so where is your problem? Growisofs depends on mkisofs and mkisofs is part of cdrtools, so you need cdrtools anyway.>1) I expect the problem is with mkisofs version 2.01 that is used in >FreeBSD (at least in 7.0), but I haven't attempted to confirm this. >Growisofs is supposed to handle large files, and so are recent >versions of mkisofs. The author of mkisofs considers 2.01 to be >obsolete. Perhaps installing a newer mkisofs is the solution (e.g. >sysutils/cdrtools-devel appears to be fairly recent)?mkisofs-2.01 is more than 4 years old. It is not just obsolete but extremely outdated. Since mkisofs-2.01 30-50% of the code has been replaced or added. Cdrtools is only a few weeks from the next major release and it would be silly not to use a recent version.
