I strongly agree with this last statements. How often do the backup group get a bad tape (do they even keep statistics of that) ? The more tapes you need to use for one restore, the more chances you have not to be able to restore. I might be a bit biased because of the industry most my customers are in, but how valuable is your data ? How much would it cost the company to loose (or have to regenerate IF that's possible) one week of data ? 2 weeks of data ? 57 days of data (if your last full is broken) ? -- Yves. http://www.sollers.ca/ _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
