Snap/flash can only copy what has been "written". It doesn't copy what is cached inside Linux. Unless you are insanely, incredibly lucky, you will be missing data if you do the snap with the systems up. If you want to back the guests up with the apps live, you need to use a backup tool with a inside-Linux client and separate writable VM data from r/o data so you can limit the downtime to just the volatile stuff. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
