1. On the Linux machine where you plan to install Acronis Management Server, install PostgreSQL:
   
   Make sure you install PostgreSQL version 9.2 or later.
   1. Install PostgreSQL:
      • on RedHat/Fedora/CentOS install as described in this manual. Additionally, install contrib modules:
        # yum install postgresql-server postgresql-contrib
      • on Debian/Ubuntu Linux install by issuing:
        # sudo apt-get install postgresql postgresql-contrib
   2. Initialize database:
      # service postgresql initdb
   3. Start PostgreSQL:
      # service postgresql start
2. Install Acronis Management Server of Acronis Cyber Backup 12.5 as described in this manual.
3. Stop services:
   # service acronis_ams stop
   # service acronis_asm stop
   # service acronis_zmqgw stop
4. Download and unpack this package. Copy all files from this package to /var/lib/Acronis/AMS/postgresql
5. Open /etc/Acronis/AMS.config in an editor and change
   <value name="AmsDmlDbProtocol" type="TString">"config:///var/lib/Acronis/AMS/dml.config"</value>
   to
   <value name="AmsDmlDbProtocol" type="TString">"config:///var/lib/Acronis/AMS/postgresql/dml_postgresql.config"</value>
   Save changes and exit editor.
6. Download and unpack this ams_postgres.exe tool. Place the tool into /usr/lib/Acronis/AMS/ams_postgres
7. Run the ams_postgres tool:
   # chmod a+x /usr/lib/Acronis/AMS/ams_postgres
   # /usr/lib/Acronis/AMS/ams_postgres
8. If you are using build 7048, Update 1 (Build 7641), Update 1 HF1(Build 7970): download and unpack libabr_ams.so and replace /usr/lib/Acronis/AMS/libabr_ams.so with the downloaded one.

   If you are using Update 2 (Build 8610) or later, skip this step.

9. Start services:
   # service acronis_asm start
   # service acronis_ams start
   # service acronis_zmqgw start

Now you can use Acronis Management Server with PostgreSQL.
