Your backups will be plain unreliable. I do it all the time for backups and audio burns. It works fine, even while I am launching/using netscape and other high-resource apps. I have also done burns during the time that the /etc/daily runs go, which hits the disk pretty hard. Note that cdrecord has built-in buffering and my SCSI CDRW (ricoh) has a 2Mb internal buffer; this may help. On the otherhand, I have garden-variety IDE disks, which should limit me. I always write checksums and read the data off the CD to verify, and I have not had any errors in ~100 backups to a CDRW or CDR (I usually use a rewriteable, just saves the hassle of buying media, and occasionally burn a permanent CDR to store off site). For me, the choice of how to do backups on a $400 budget was clear. My CD-RW gives me everything I need for backups, *plus* the ability to make CDs to share with others, and audio CDs for fun. If you are considering a CDRW, don't be scared off by the prospect of unreliable burns. It isn't that sensitive. -- ------------------------------------- David Deaven deaven@execpc.com http://www.execpc.com/~deaven To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
