Backup/Recovery

This happened because the user did not add the -w option or the --no-password option to pgx_dmpall. By using these options, the user won't be prompted for a password.

For details refer to Fujitsu Enterprise Postgres Reference Guide > Chapter 3 - Server commands > 3.2 - pgx_dmpall.

Resolution

Run pgx_dmpall with the -w option or the --no-password option. If either is used, one of the following configuration must also be in place.

• Using the pgpass.conf

  Write the password in the %APPDATA%\postgresql\pgpass.conf file (where %APPDATA% refers to the Application Data subdirectory in the user's profile).

  For details, refer to PostgreSQL documentation > Part IV - Client interfaces > Chapter 34 - libpq-C library > 34.16 - The password file.

• Using the password file pg_hba.conf

  Specify "trust" in the "auth-method" field of the pg_hba.conf file in the data directory for the database cluster.

  For details, refer to PostgreSQL documentation > Part III - Server administration > Chapter 21 - Client authentication > 21.1 pg_hba.conf file.

These methods allow batch processing without password input.

Fujitsu Enterprise Postgres databases can be backed up and recovered in the following ways, both of which can be performed without stopping the database:

• Using WebAdmin for backup and recovery
• Using pgx_dmpall for backup and pgx_rcvall for recovery

It's also possible to back up the database without stopping it using PostgreSQL pg_dump.

pgx_dmpall saves backup files to the directory set in backup_destination in postgresql.conf, so when saving the contents of the backup directory to another location, make sure you save all content of this backup directory.

When restoring, restore the content of the backup directory to the same state as the source.

For details on pgx_dmpall, refer to Fujitsu Enterprise Postgres Reference Guide > Chapter 3 - Server commands > 3.2 - pgx_dmpall.

In postgresql.conf, enable WAL archiving by setting wal_level, archive_mode, and archive_command parameters as follows:

wal_level = replica (or, when using logical replication, set to logical)

archive_mode = on

archive_command = 'cp %p <archive directory path>/%f'

(Note that in releases prior to 9.6, wal_level parameter also allowed the values archive and hot_standby. These are still accepted but mapped to replica.)
