Hi there, I have a question concerning the use of dd to make a backup of a harddisk onto an *identical* backup disk using FreeBSD 2.2.8: If the disk copied contains a live filesystem, which is modified by user processes all the time, what can there be said about the dd copy? I tried this and the only problem fsck detected was that the clean flag isn't set, other than that there were no problems. Before you all start mailing me about how stupid it is to use dd as a backup mechanism: I use this in order to maintain an instant bootable backup. So if the primary disk crashes I unplug it, reboot the system and I have a working system again. Please respond to my email address because I am not a member of hackers Thanks in advance for any help, Pete -- Peter Weymarshausen BowTie Technology Email: P.Weymarshausen@bowtie.nl WWW & Databases To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
