Hi,

I need to write bacula backups to bluray discs.
It's written that ISO9660 doesnt support files larger than 2GB, although I tried to wrote files than larger with growisofs , and by checking with md5sum these seem to be ok on DVD (tested with dvd-writer and dvd).


[root@o7 isos]# uname -a
Linux o7.workstation 2.6.18-194.3.1.el5 #1 SMP Sun May 2 04:17:42 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

Is there some good practice/guide/howto for getting large backups to bluray with centos/rhel 5 (kernel 2.6.18).
UDF seems to be out of question because kernel older than 2.6.26.

Thanks in advance.

Why ?
RHEL supports UDF and has done for years. There was a bug in the RHEL5 release that limited filesizes to 1GB, but that was later fixed. (kernel-2.6.18-92)
