XamFlow Server Backup Guide

Warning

Backups are critical and require expert handling. Please carefully read this document and consult with your system administrator or IT department.

This backup guide describes the process to backup XamFlow Server.

It is important that the administrator of XamFlow Server periodically creates backups of all important data.

General recommendations

  • Keep multiple daily / weekly / monthly backups

  • Store backups on-site and off-site on different storage mediums

  • Automate backups

  • Test restoring from backups periodically

Database Backup

XamFlow Server uses a PostgreSQL database.

  • Study the PostgreSQL Documentation about pg_dump

  • Ensure the database service is running.

  • Create a folder.

  • Open a console in that folder and run for example the following commands:

    set PG_BIN="C:\XamFlow\PostgreSQL\15\bin"

    %PG_BIN%\pg_dump.exe --dbname=xamflow --file="database.dump" --format=custom --username=postgres --verbose >pg_dump_stdout.log 2>pg_dump_stderr.log

    type pg_dump_stdout.log

    type pg_dump_stderr.log

  • Type the password (default: postgres) when prompted.

  • Check the pg_dump_stdout.log and pg_dump_stderr.log files for any error message.

  • This creates a consistent backup of the database.

File Storage Backup

  • Copy the files from the File Storage mappings.

    • Consult the WebAdmin panel for File Storage mappings in case the location was adjusted.

Other Files

  • Copy other files like config, license or log files from %localappdata%\Lucid_Concepts_AG.

Other Computers

  • Create backups of files on other computers, e.g. worker computers, desktop computers, file storage computers.

Restore Database from Backup

Warning

Restoring the database is a critical operation. A clean database is required as a starting point. Dropped database objects not present in the backup cannot be restored.

  • Study the PostgreSQL Documentation about pg_restore

  • Consider adjusting flags like –create below according to the specific scenario.

  • Ensure the database service is running.

  • Stop all worker services.

  • Open a console and run for example the following commands:

    set PG_BIN="C:\XamFlow\PostgreSQL\15\bin"

    %PG_BIN%\pg_restore.exe --create --dbname=postgres --username=postgres --verbose --exit-on-error database.dump >pg_restore_stdout.log 2>pg_restore_stderr.log

    type pg_restore_stdout.log

    type pg_restore_stderr.log

  • Type the password (default: postgres) when prompted.

  • Check the pg_restore_stdout.log and pg_restore_stderr.log files for any error message.

Restore Files

Warning

Restoring the files is a critical operation. The files should be consistent with the database.

  • Restore the files at the same time as the database backup, so they are consistent.
