2.1 PrerequisitesThis section describes the supported database server versions, the required supporting software, etc.
• Note: BART currently runs on only 64-bit platforms.2.1.2 Required SoftwareThe following components must be installed on the BART host as well as on any remote database server hosts on which incremental backups are to be restored (These remote hosts also require installation of BART.):
• Postgres libpq library
• Postgres pg_basebackup utility programThe BART host components are installed using EnterpriseDB RPM packages. See Section 0 for installation instructions for these components.
• Full base backups are taken using the pg_basebackup utility program. In the global section of the BART configuration file, parameter pg_basebackup_path specifies the complete directory path to the pg_basebackup program file to be used by BART for taking full base backups. See Section 4.1 for information on this parameter.For information on pg_basebackup see the PostgreSQL Core Documentation available at:There are restrictions that affect how full base backups can be taken on Postgres database servers depending upon the pg_basebackup version and the Postgres database server version.Database servers can only be backed up by using pg_basebackup of the same or later version than the database server version. For example, pg_basebackup version 9.5 can back up database server version 9.5, but it cannot be used to back up database server version 9.6.
