    I created a batch to run the backup command pgx_dmpall and attempted to run it automatically, but I am prompted for a password which prevents me from automatic execution. What is the cause and how can I run the command automatically?KB1001

    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 13 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.

    These methods allow batch processing without password input.

    How do I perform an online database backup and restore which ensures data consistency with no system disruption?KB1002

    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

    For more information and precautions on these backup methods, refer to FUJITSU Enterprise Postgres 13 Operation Guide > Chapter 3 - Backing Up the Database.

    For information on how to recover after backup using these methods, refer to the following in Operation Guide > Chapter 15 - Actions when an Error Occurs:

    It's also possible to back up the database without stopping it using PostgreSQL pg_dump. For more information on these backup methods, refer to PostgreSQL 13.1 Documentation - Chapter 25. Backup and Restore.

    I am planning to copy an online backup made using pgx_dmpall to a network drive or external storage to store it while the database is running. Are there any folders in the backup destination that I should exclude when copying the content?KB1003

    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 13 Reference Guide > Chapter 3 - Server Commands > 3.2 - pgx_dmpall.
