I didn't even think about the possibility of dump not being forwards compatible (8-( In passing, you may find the buffer port useful. I spent a while a couple of years ago experimenting with settings, and find this sort of thing sufficiently fast: /sbin/dump -L -0 -u -C 32 -b 32 -f - /home | /usr/local/bin/buffer -s 32k -m 16m -t | gzip | /usr/local/bin/buffer -s 32k -m 16m -t > new/home.dump.gz That is, big buffers and block sizes for dump, with a 16 MB buffer of either side of gzip to absorb some of the delays in compression or writing the dump file. Sorry, no timings available at the moment. Note: * Remove the -L under Release 4 * When the above line is executed, the script has changed its CWD to the dump directory, usually on an NFS mount. * When dumping to the same machine, I include -h 0 and make the dump directory (and a slew of other recoverable by other ways ones) nodump with chflags nodump. -- Adrian Wontroba _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
