In fact at one stage I took an ldif from the replica and used it to restore the master....so it seems pretty robust. If you're about on irc at all tomorrow I may pick your brains about your experiences. I kind of ruined my test environment this afternoon. I had to redeploy about 15 virtualized guests on my tiny microserver at home. That took quite a while ;-) > > In terms of filling with water, depends on how long for but the physical parts of the hds ie platters and arms should survive that.....electronics might as well.....in which case swapping one half (I assume you have a raid1) to a new box and syncing it might work....then drop out the old disk and slot in a new one...same with fire / smoke damage. NB One of the recommended ways to put out a fire in a server room is water misting using de-mineralised water.... I was merely giving a radical scenario in jest. My main purpose is to produce an IPA 'specifc' backup/restore procedure that doesn't rely on other technologies. Starting with a similar goal to restoring an AD system state backup for example.

Another way might be rsyncing the ldif over ssh to a remote site......maybe even email it to say google....it shouldnt be very big, ours is 400k at the moment. > > regards > > Steven Jones > > Technical Specialist - Linux RHCE > > Victoria University, Wellington, NZ > > 0064 4 463 6272 > > ________________________________________ > From: <a class="moz-txt-link-abbreviated" href="mailto:freeipa-users-bounces@redhat.com" target="_blank"> freeipa-users-bounces@redhat.com</a> [<a class="moz-txt-link-abbreviated" href="mailto:freeipa-users-bounces@redhat.com" target="_blank">freeipa-users-bounces@redhat.com</a>] on behalf of Dale Macartney [<a class="moz-txt-link-abbreviated" href="mailto:dale@themacartneyclan.com" target="_blank">dale@themacartneyclan.com</a>] > Sent: Wednesday, 27 June 2012 11:27 p.m. > To: <a class="moz-txt-link-rfc2396E" href="mailto:freeipa-users@redhat.com" target="_blank"> <freeipa-users@redhat.com></a> > Subject: [Freeipa-users] IPA Backup / Restore - Everyone's favourite problem child! > > Howdy all > > We have had quite alot of discussions on the list about this process but > I'd like to get some documentation together so we are all speaking the > same language. > > So last night I wrote a script to backup IPA based on the below article. > > <a class="moz-txt-link-freetext" href="https://access.redhat.com/knowledge/solutions/67800" target="_blank"> https://access.redhat.com/knowledge/solutions/67800</a> > > This is fine and dandy.
