How do I backup profile manager database on OS X Yosemite?

Hello guys,

I'm struggling to find an answer on how to backup profile manager database(devices, groups etc.) on Yosemite(server 4), so far I only found a few threads for Mavericks (10.9) & Server 3 saying to type the following command via terminal: "sudo pg_dump -U _postgres -c device_management > $HOME/device_management.sql"

Although this command applies to Mavericks(server 3) I decided to give it a shot but as expected I got this error message:

"pg_dump: [archiver (db)] connection to database "device_management" failed: could not connect to server: No such file or directory

Is the server running locally and accepting

connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?"

I also tried to backup & restore profile manager's database with TimeMachine but unfortunately it didn't worked..

It seems that TimeMachine misses the profile manager's data folders(see thread: Profile Manager not being backed up in Time Machine?)

and I saw that other people also complained about this problem.

As we're a company who holds thousands of devices & integrates them on daily basis to profile manager, I would be very pleased to know how to backup our Profile manager's database.
Please see this question as HIGH importance, I really hope to get an answer ASAP..

Thanks in advance for all the repliers! 🙂

Yours sincerely,

Daniel Adler.
