Open directory mac os x server 10.8

It is described somewhere but it basically runs a backup script before running TM backup. Jul 28, 2: The ServerBackup process does archive OD. See the additional information section of this article:.

Aug 20, 8: Actually, I believe that I found my answer with the "slapconfig" command. I have not tried it in production, but "sudo slapconfig -backupdb" is supposed to do the trick, according to the man page of slapconfig.

For starters, I would encrypt the backup file which it probably doesn't do by default. Any other insights? Sep 1, 6: I am not sure if this is supposed to run automatically with Time Machine, but if you manually load this launchd job, it will run daily:. Oct 22, 9: I would caution you heavily against doing this unless you have disabled backup of the System folder in time machine.

Serverbackup drops it's backups in. ServerBackup in the root of the system drive which then gets picked up by TM, which is actually pretty great. However it does need to be scheduled to run using chron or it will not do anything. This may or may not be what's called when time machine backs up open directory, but I've had multiple cases in multiple environments all documented by apple where because of one reason or another the time machine backup actually trashes OD completely. Sr level engineers recommended strongly to me that the only sure fire way to backup OD was to script it and exclude it from time machine.

I'm still not settled on how I want to standardize this in my environments, given some discussions I've had with apple server support about restoring those backups. I don't know if they were just being lazy, but they all really want you to just roll your server back using time machine Oct 22, 3: Apple support told me to use this to backup and restore Open Directory.

It worked fine. You can protect the backup with a password. I am now tempted to make a daily backup this way ;-. I did a restore using time machine some time ago and that did not work out very well as it seemd that it had restored a very old version of the postgress database. So calendars, wiki, etc. I do not know what caused this, but since then I do not trust time machine backups very much for os x server. Nov 9, 2: Has anybody wrote a script for cron or launchd for mac let to automate the task?

Nov 9, 3: Off course, you can always use Perl for this. I think I modified this back in the day from someone else don't have any credits, sorry. This has been taking backups for well over a decade. Mar 15, 2: While it might not be suitable for everyone, a solution that has worked quite well for me is to just periodically make disk images of the server. Not as easy to automate, but much more reliable when it comes to restoring a dead OD server.

Plus, it backs up user passwords this way, whereas just backing up the ldap database does not. Unfortunately, Apple doesn't seem to think that we need tools to fix broken directory services, because the company seems to live in a delusional bubble where nothing they create ever breaks or behaves unexpectedly. While Server Admin offered a built-in Backup and Restore feature for Open Directory, it was an illusion of safety, because account passwords were not included.

So yes, you could restore your directory nodes, such as group memberships and policy settings but it didn't do any good since the user accounts were ruined. I have been fortunate enough to be in situations where I've had to rebuild directory services from scratch on several occasions because backup and restore wasn't good enough for one reason or another.

An ideal place to start

So over the years, I've come up with my own "best practice" for setting up Apple Open Directory, because I like to minimize downtime in the event of a disaster. In most cases with Open Directory, they provide no actual fault tolerance or any sort of automatic load balancing. All they are good for is corrupting your LDAP database when they fall out of sync.

So getting rid of these actually reduces the chance you will actually need to restore the database in the first place. Obviously if you do have remote offices, you will still probably need at least one replica. Make sure the remote clients all point to that replica and NOT your primary master. Better yet, switch to AD for this scenario.

Apple OS X Server: How to set up Open Directory

Alternatively, you can also "Option Boot" the server to an external FireWire disk that has the same or newer copy of OS X installed and plenty of free space to hold your backup image. Yet another alternative would be to use a custom NetBoot image that has a server volume available for writing the backup to.

If your OD server is dedicated to the purpose and only has the OS installed and OD configured, the process will take about minutes or so to complete. Despite the gargantuan size of problems it can create, the OD database itself is actually very small. Meanwhile, you can tell Disk Utility to "Scan the Image for Restore", which basically reorders the blocks in the image file you just created so that it can quickly be reapplied to any drive big enough to hold it. Assuming you did everything correctly, the image will restore using block-level copy and will complete in about 10 minutes or less.

The drawbacks to my approach are fairly obvious. Primarily, it's just the downtime and manual labor involved in creating the backup. So if your database changes dramtically on a weekly basis, then this may not be the right approach for you.

In my experience, however, aside from replacing computers, adding new policies, or users changing passwords, the database hardly ever changes. At least not to a degree that will matter much in a disaster recovery situation. But taking an hour every other month to make a backup is worth it if you seriously rely on your OD.

I usually set things up so that I can do all of this remotely after hours. Which is a bit trickier, because having your OD server down often disables many, if not all, of your network services, too.

For me, the benefits to my approach outweigh the drawbacks. In the event my OD server has a melt-down or gets corrupted for whatever reason, I can usually have everything back up and running tip-top shape in less than 20 minutes. Even when I had to restore an OD server from a backup image that was over a year old, I was able to get the company back up and running in less time than it would have taken for me to read the slapconfig man page.

Some of these can act as a directory service of sorts https: A hosted directory service provider Directory as a Service like Jumpcloud. There are probably dozens of other options as well please feel free to add them in the comments section of this article.

To help with this, I wrote a little ldif to csv converter and posted it here.

You can also repeat this process for Groups, if needed.
