Topic: howto setup a semi-redundant server

[dalesyk]

Hello,
   I run SME 6.0 as a home web/email/vdomain server over cable broadband.  My cable service has been out over a week (Time Warner/Houston) because of some upstream issue.  This made me think that it would be nice to have a friend with home SME/broadband use his server as a backup for mine and vice versa.  With the lazy admin addon, it seems that the user/ibay/vdomain stuff could be automated as long as names do not overlap.  Keeping the sites in sync should be easy (cron.daily rsync over ssh), but I'm not sure about how to handle mail.

   Has anyone done this?  Is there a good howto on this subject?

Thanks,

Dale

hi dale,

your isp can setup a backup mail server for you, that means a second mx record will be added for mail handling, and in the event your primary mail server should fail, all mail will be handeld by the backup mail server.

if you use dns services from easydns or dyndns.org just setup a new box and change your mx configuration.

it's very easy, would be more work if it's you running the dns stuff

Dale, I cannot help you with your problem, but I've jumped for joy reading your topic.  I would like to backup (tar or rsync) a couple of ibays from one box in location A to another box in location B over ADSL.  Running vs 6 at each end, and installed Dungog custom backup contrib which allows me to do exactly what I require over a LAN under Samba.  But I am new at this game, and do not know how to setup the link over ssh.  Can you clue me up if time allows please - what do I have to do on both sides?  Many thanks.  chris.

I think EasyDNS http://www.easydns.com provides this function. I know some ISPs do not like users having their own email server.
