What would it take to find a solution to this in the S3/EC2 environment? Could one carefully segregate r/o from changable part of the image and backup the changable part every hour and then journal an hour's-worth of everything to external storage, too? .. or sumpin' like that -- I'm hand-waving because I don't have sufficient expertise. Is this possible? .. feasible? Regards, ..jim -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
