Well, that is the logical conclusion from what I said; although I was discussing more my specific case, where it was shared data at /srv/shared. That said, I would have thought it was sensible in the ideal world to have no data on the LTSP server. It has the benefit that the synchronisation process will have little or no impact on the performance of the LTSP servers and leave you free to update and upgrade the server with the knowledge that the precious data is elsewhere. I have never tried this approach it has to be said. It would have some performance hit, but it should be pretty minimal with gigabit network, it would become more serious with video editing or rendering your next blockbuster movie, but for normal documents it should work fine. Perhaps someone has experience of this sort of set up? That said, it requires yet more hardware and yet more cost. And, if your users are only operating during the day, a night-time sync should have minimal impact. Just be aware that rsync and unison are both likely to have a hit on server performance, so either try and run the process out of hours, or separate from the server. > I know you can set up rsync to work both ways -- you just need to > specify how it acts when it comes across a newer file on the server, > and make sure that the two servers have identical clocks. > > > That said, whilst your case sounds more difficult - sharing home folders - > > in practice it is probably easier, as you should never have both copies > > being edited at the same time.

Yikes, you should consider moving to an ISP that does not use caps. -- Chris Roberts http://chrisjrob.wordpress.com/ ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
