This generates multiple volumes by appending a sequence number if necessary. For example, on a /home dump of >2GB, the commands ddate=`date +%m%d%y-%H%M%S` dump -0uM -b 32 -B 2097142 -f /mnt/home.$ddate.L0.dump -L "abit:/home" /home generate /mnt/home.092801-130439.L0.dump001 /mnt/home.092801-130439.L0.dump002 each guaranteed to be 10K under 2GB. Fixes potential portability issues also. rgds, tim. --
