The plug-in offers the following backup methods:
|
• |
SQL Logical Data Dump: Selecting this method performs logical data dumps composed of SQL commands that are used to reconstruct the PostgreSQL data. The PostgreSQL Server utilities pg_dump and pg_dumpall are used to perform SQL Logical Data Dump Backups. This option supports database-cluster backups and individual database and table backups in different backup formats. |
|
• |
File Level Data Copy: If you are using PostgreSQL Server 9.6 or later, this option supports archive-based backups and restores of the complete PostgreSQL database cluster. This option performs a physical backup of the PostgreSQL Server data files and works in combination with the pg_start_backup and pg_stop_backup utilities. |
The plug-in supports backups in Plain-text SQL Script File, TAR Archive, and Custom Archive backup formats, which can be used to back up an entire database cluster or individual databases and tables.
|
• |
Plain-text SQL Script File: This format generates a plain-text file that contains the SQL commands required to reconstruct the database to the state it was in at the time of backup. |
|
• |
TAR Archive File: This format generates a tape archive (TAR) file that is not compressed. |
|
• |
Custom Archive File: This format generates an archive file that is compressed by default. It lets you select the compression level and can be used for tables that are larger than the maximum file size supported by the OS. |
The plug-in provides the following backup types:
|
• |
Full Database Cluster: This option backs up all the databases within the cluster in the selected backup format. It also includes a backup of Global Objects, which are in the form of a Plain-text Script file, regardless of the backup format specified. The plug-in automatically includes the configuration files when the database cluster is selected; however, you can exclude it from the backup if applicable. |
|
• |
Individual Database/Table: This option backs up selected databases or tables in the selected backup format. You can use it to back up databases that are updated more frequently than others or use it as a source when creating test environments. This option does not include Global Objects when the databases or tables are backed up individually. |
|
• |
Global Objects Only: This option backs up only the Global Objects, which you can use to back up the updates made to the database users, groups, and access permissions. |
|
• |
Configuration Files Backup: You can back up the configuration files with any of the preceding backup types, or separately. The following files are included when you select this option: |
|
• |
postgresql.conf: This file is the primary server configuration file that contains all the parameter settings and directives. |
|
• |
pg_hba.conf: This file is the host-based authentication (HBA) or client authentication file. |
|
• |
pg_ident.conf: This file stores ident maps, excluding sameuser, and is used for ident-based authentication. |
