[Vserver] keeping a mirror machine synched
I have a stock install of Debian 3.1 with the kernel 2.6.13-vs2.0.1-pre2-686 and util-vserver-0.30.209 (I think) and several production vservers on one (32 bit) machine. I also have an identically configured second such machine. I run a nightly script (over a private network) which does the following synchronisation from the production to the backup machine: rsync -a -e ssh /home/ [EMAIL PROTECTED]:/home/ rsync -a -e ssh /usr/local/etc/vservers/ [EMAIL PROTECTED]:/usr/local/etc/vservers/ My vservers live in /vservers which is a symlink to /home/vservers. Apart from /usr/local/etc/vservers/ is there anything else I should synch? Another question: Debian 4.0 is ante portas. Given that 3.1 had everything way out of date, can one rely on stock vserver kernel and tools in Debian 4.0?
