Tar seems to be o.k. dump most time can recover (better survive) 2 hanging SCB! But software which does continuous write lage blocks (30MB) and have a really high optimizing buffer queuing algorithm seems to mak problems, please test ftp://ftp.zn.ruhr-uni-bochum.de/pub/linux/afbackup-2.11.3.tar.gz Lars -- E-Mail: | Lars Koeller Lars.Koeller@Uni-Bielefeld.DE | UNIX Sysadmin lkoeller@cc.FH-Lippe.DE | Computing Center PGP-key: | University of Bielefeld http://www.nic.surfnet.nl/pgp/pks-toplev.html | Germany ----------- FreeBSD, what else? ---- http://www.freebsd.org ------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
