Back-up data

The data handled by Backlog is stored in the following files, which should be backed up regularly.

Creating an advanced configuration file

Create docker-compose.override.yml on the same level as docker-compose.yml. In docker-compose.override.yml, list the services you want to change and their configuration values. After it’s created, restart with the Start command.

For example:

version: "3"

  services:
    backlog-web:
      environment:
        ...

    backlog-api:
      environment:
        ...

Get more information.

Integrating with Active Directory

Change the port number of LDAPS

For an LDAPS connection, enter the LDAPS port number in the advanced configuration file you created. After it’s created, restart with the Start command.

backlog-api:
  environment:
    - LDAPS_PORT=8636 #Default 636

backlog-web:
  environment:
    - LDAPS_PORT=8636 #Default 636

Use Active Directory Certificate Service

If you use an LDAPS connection and the Active Directory Certificate Service, place the certificate issued by Active Directory Certificate Service in any directory. After it’s placed, add the following information to the advanced configuration file you created, and restart with the Start command.

backlog-api:
  volumes:
    - /path/to/cert/dir:/mnt/certs #Please replace `/path/to/cert/dir` with the directory where you placed the certificate
  command: -Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

backlog-web:
  volumes:
    - /path/to/cert/dir:/mnt/certs #Please replace `/path/to/cert/dir` with the directory where you placed the certificate
  command: -Dcom.sun.jndi.ldap.object.disableEndpointIdentification=true

Create users with Active Directory

Create Backlog users with information from Active Directory. Set up zone definitions and SRV resource records for Active Directory before operation. Active Directory is supported on Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019. Get detailed instructions.

Regenerate the search index

If the results of a keyword search are not displayed correctly, run the command to regenerate the search indexing. Note that playback is delayed if there’s a large amount of index data.

Problem with the issue search (issue list)

Use the following:

docker compose up elasticsearch-tool

Problem with global navigation keyword searches

Use the following:

docker compose up solr-tool

Change the speed of search index re-generation

Change the limits for indexing jobs in the advanced configuration file you created. After editing, restart with the Start command.

backlog-job-worker:
  environment:
    - BACKLOG_WORKER_JOB_INDEXING_ISSUE_JOB_PERMITS=16 # Default 6

Change maximum of bucket size requests

If the wiki has too many characters and can’t be saved, for example, change the bucket size limit in the advanced configuration file you created. After editing, restart with the Start command.

backlog-api:
  environment:
    - MAX_MEMORY_BUFFER=25MB # Default 20MB
    - MAX_DISK_BUFFER=25MB # Default 20MB

backlog-web:
  environment:
    - MAX_MEMORY_BUFFER=25MB
    - MAX_DISK_BUFFER=25MB

Change the maximum number of simultaneous Nginx connections

Copy nginx.conf locally with the following command. After editing, restart with the Start command.

docker compose cp nginx:/etc/nginx/nginx.conf .

Edit nginx.conf and docker-compose.override.yml.

nginx:
  volumes:
    - ./nginx.conf:/etc/nginx/nginx.conf

Get more information on configuring nginx.conf.
