I don't think tcopy is double-buffered; if you only have one file on that tape and know the blocksize, dd if=/dev/nrsa0 bs=##k | dd of=/dev/nrsa0 bs=##k should be much faster. If you have multiple files or unknown blocksizes, the cptp command from the MAG package at http://www.cs.vu.nl/~dick/mag.html will preserve filemark and blocksize info through pipes, so you could do a cptp | cptp pipe. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
