| Hi I've been lurking for a couple of weeks, but thought I'd introduce myself as I now have a problem I hope someone can help me with. I run an IT consultancy, specialising in Apple Mac, Linux and UNIX support. One of my customers has a server running SUSE 9 with a simple backup script backing up onto DVD-RW. -----8<----- #!/bin/sh # Simple DVD backup # Kevin Davidson <kevin@xxx.xxx.xxx> LOG=`mktemp` exec >> $LOG 2>&1 ISOPUB="indigospring.co.uk" ISOPREP="kevin@xxx.xxx.xxx" ISOVOL="BKP-`date +%Y%m%d`" mkisofs -v -l -R -pad -J -V $ISOVOL -P $ISOPUB -p $ISOPREP -o /var/tmp/dvd.iso /home umount /media/dvdrecorder cdrecord driveropts=burnfree -dev=0,0,0 -dao fs=6m blank=all -pad /var/tmp/dvd.iso mail -s "Backup completed $ISOVOL" backups < $LOG rm $LOG exit 0 -----8<----- Unfortunately, it seems to run fine for a few nights and then stops for no apparent reason. -----8<----- scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.25 cdrecord: Warning: using inofficial libscg transport code version (okir@xxx.xxx.xxx '@xxx.xxx.xxx(#)scsi-linux-sg.c 1.75 02/10/21 Copyright 1997 J.

Alternatively, does anyone have a better suggestion or I might have to suggest buying Retrospect to run on one of their desktop PCs :-( A client backing up a server just seems wrong to me.
