...and then Clemente said... % % Hi there, Hi! % My hosting company tells me that they need to take down the MySQL server % every day for 30 to 60 minutes to make a backup. This is the quote: % "Please note that mysql is shutdown daily sometime between 3am and 9 am % US eastern for 30 minutes to an hour. This is get a good backup of all % mysql databases on the server during the daily backup process." Hmmm... Speaking as a SysAdmin, that looks like a cover-all-bases general announcement. At the very least you should be able to predict exactly when your host will be unavailable; a 6-hour window is too wide. The same may be the case for the mysql downtime; you may in fact only be down for a few minutes if at all. I would check with your support and get specifics on how, when, for how long, and why any part of your server will be unavailable. % % Is this normal? This implies that my dynamic generated web site is down % during a 2.1% to a 4.2% of the time (not counting any other server down % time). I hear that normal down times for web sites are more like 1% or % less. Indeed. If your provider is going to take down your web site on a daily basis, you may need to find another provider. While I applaud their dedication to detail and commitment to stability, it doesn't seem to serve the customer too well overall! <shameless_plug>We do hot backups of mysql with no down time. Drop me a note if you'd like more info on how to switch to us.</shameless_plug> % Is this really necessary? Does MySQL requires to be shutdown to generate % a good backup? No, it doesn't; one can use mysqlhotcopy, a filesystem copy, a slave server, or backup software smart enough to quickly lock things as it reads a table -- just to name a few of the *many* possibilities and permutations thereof. % Any comments are welcome. Thanks a lot. % % -- % % Clemente Zamora % GlobalReservas % (http://www.clementezamora.com) HTH & HAND mysql query, :-D - -- David T-G * There is too much animal courage in (play) [EMAIL PROTECTED] * society and not sufficient moral courage.
