My system hangs when I'm doing full backup to DAT drive with tar or cpio. I have used QIC drive for partial backups. Now I borrowed DAT drive and tried make full backup. System hangs randomly ie it takes 5-55 minutes before it happens. I tried five times before I changed bt driver to aha (AMI SCSI controller is compatible with buslogic 742a and Adaptec 1542). With aha driver backupping works like a charm. Making full backup taked over an hour but it worked smoothly. I even tried it twice. Any good explanations?
