Backups

SD Elements provides a mechanism to create and restore backups on the same instance.

Create a server backup

Follow the steps below to create a backup of server customizations. The backup can be used for the purposes of server restoration.

Prerequisites:

  1. SSH credentials for sde_admin or sudo access.

  2. The backup you wish to create and restore will be performed on the same SD Elements instance (OVA file).

Steps:

  1. Access the SD Elements server SSH console as sde_admin.

  2. On the command line, run

    sudo sde backup create

A file is created in /docs/sde/backup/ by default, this value is configurable via the --output-dir flag. Its filename matches format sde-backup-SDE.Version-YYYY-MM-DD-HHMM.tar.gz where SDE.Version is a release name. For example,

sde-backup-4.12.22-2018-03-01-1201.tar.gz

The backup archive contains:

  • database encryption keys

  • core configurations in the YAML file

  • SAML certificates

  • Webserver SSL/TLS certificates

  • uploaded media files.

Further options are available, use sde backup help to view additional command arguments.

Restore a backup

Restore a server to an earlier state using a previously created backup.

Prerequisites:

  • SSH credentials for sde_admin or sudo access.

  • The backup you wish to create and restore will be performed on the same SD Elements instance (OVA file).

  • An existing backup archive whose version is identical to the active release of SD Elements.

Steps:

  1. Access the SD Elements server SSH console as sde_admin.

  2. On the command line, run

    sudo sde backup restore -i /file_path/backup_file.tar.gz

The files from the backup archive begin to restore, and a backup archive of your current database is created:

Schedule a backup

Perform regular application backups using the guidance below.

Prerequisites:

  1. SSH credentials for sde_admin or sudo access.

Steps:

  1. Schedule sde backup create to run as a cron job using details from section Supported system configuration

      cron::crontab::jobs:
 backup_sde:
   command: 'sde backup create'
   hour: '*/12'
