I regularly use dump(8) with snapshots to back up my server.While this seems to have been working perfectly well so far, upon (re)reading the man page for dump(8), I have noticed a somewhat scary pair of lines in the paragraph describing the option for -C <cachesize> (emphasis with stars mine): [Use of this option] will greatly improve performance at the cost of ***dump possibly not noticing changes in the file system*** between passes. ***It is recommended that you always use this option when dumping a snapshot.*** Does anyone know what, exactly, this means?
no, in my experience it's no difference in speed with this enabled or not. _______________________________________________ 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"
