Re: Approx. restore time estimate
I was wondering if 24, 48, 72 hrs or even a lifetime was the order of time. I am now approaching 24 hrs. probably wait until my geriatric years and come back to look at the machine ... lol!!! Or would I have been better off using dd if=/dev/* of=output/path/filename [options] All other things being equal, would the removal of the "restore" overheads be significant relative to those from dd .

IME, restoring from disk or tape makes little difference, if you're doing a full restore, and once the restore process is up and running. The bigger bottleneck is the write speed of the disk(s) you're restoring to - it's always slower to write than to read, often by a very large margin.

I don't know of anything that isn't a bigger can of worms in a file system of any complexity to speak of. BTW I should have mentioned that I was restoring from a disk file rather than from a tape I was speaking of disk to disk. -- Lars Eighner http://www.larseighner.com/index.html 8800 N IH35 APT 1191 AUSTIN TX 78753-5266 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Thanks! That might explain. Is there an alternate process you would recommend with at least equal reliability.
