On our databases, I use mysqldump to dump to a text file. The backup is piped through gzip to reduce the size on disk. This has the advantage of being portable between architectures, robust, and human-readable. I also run with update logging turned on, and turn over the logfiles after each backup. This way I can restore the database to any point in time by restoring the next earliest backup, then running as much of the update log as necessary to get to the desired point. I use a script with the 'find' command to weed out old backups and update logs older than a certain number of weeks. All of this is run nightly by cron entries. The disadvantage of this method is that mysqldump can take a while to dump large databases, and the tables are locked during the backup process. If this is a problem, you should probably investigate mysqlhotcopy. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
