I am trying to replace an older DLT tape drive (which doesn't like to eject tapes any more) with a new Quantum DLT-4 drive. Its connected by internal SCSI and seems to be set up right. But after DAYS of running a tar command, its still not done backing up 60GB. The old drive could backup 70-80GB in about 7 hours. I changed my backup script to include a -v flag in the tar command, and it now lists hundreds or possibly thousands of files. But it never even gets to /home before I killed the process (after 9 hours in this case). Any suggestions? If it helps, the backup script and output from camcontrol follows. However, this script is the same one that worked on the other drive. A quick test with a Knoppix disk suggested that the backups ran faster in Linux. Not positive of this, but it might be true. $ cat /etc/periodic/daily/910.backups #!/bin/sh # echo echo "Tape archives:" dow=`/bin/date +%w` if test "$dow" -gt 1; then echo " Beginning backup." /usr/bin/uptime /usr/bin/tar -cvpX /usr/local/etc/backups/skiplist-relative.txt -f /dev/sa0 -C / . /usr/bin/uptime else echo " Today is a weekend. Skipping backups." fi $ camcontrol devlist <SEAGATE ST373207LW 0004> at scbus0 target 0 lun 0 (pass0) <SEAGATE ST373207LW 0004> at scbus0 target 1 lun 0 (pass1) <SEAGATE ST373207LW 0004> at scbus0 target 2 lun 0 (pass2) <LaCie BigDisk Extreme+ 3.AA> at scbus1 target 0 lun 0 (da0,pass3) <QUANTUM DLT-V4 0A00> at scbus2 target 4 lun 0 (sa0,pass4) Any help is greatly appreciated. Thanks in advance, Jaime
