Simple answer: no. Linux uses caching in RAM extensively. You won't get a clean backup unless the Linux guests are down. Same with VM spool/page space, etc. See the patches I just posted for Amanda and the accompanying paper for a way to do Linux backups cleanly. The VM disks don't change much, so you could probably manage them with flashcopy. ---------------------------------------------------------------------- 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
