Introduction

This section describes how SoftXS internal and customer data is backed up.

Basic Strategy and Organization of Backup

• Backups of critical data are made locally on the servers where the data is managed.
• Backups are made on a nightly basis, typically using cronjobs.

• Local backups are stored in the local file system in staging areas. See File System Structure below.

• Backup servers make copies of staging areas of the servers on a nightly basis.
• There are multiple servers acting as backup servers.
• On one of the backup servers offsite backups are made to USB drives, which are stored in a bank vault

Site Backups

Data is divided into sites, where a site represents a system that manages a collection of data. Typically sites are customer DrawMGT systems. Sites are also used to represent the set of wiki systems and the SoftXS development cvs root.

Site are responsible for their own backups, and are typically implemented using a cronjob, making use of the following scripts:

• backupClient.pl - A script that makes backups. It is located in the venture-lib CVS tree at etc/backupClient.pl

• mailcron - A script that report cronjob errors via email. Stored in venture-lib CVS tree at etc/mailcron

These scripts are described in detail below.

File System Structure

On backup servers the backup for locally managed data is stored in the following path:

•     /e/{volume}/backup/business/local/(intern|obsolete|sites)/{site}

• volume - typically 'vol001' or 'vol002'

• intern|obsolete|sites

  • intern - internal SoftXS data, including data from internal DrawMGT system

  • obsolete - backup data that is no longer actively changed, including DrawMGT data from project that are completed (and not running as live arcive systems.

  • sites - backups of customer DrawMGT systems

• site - the name of the customer site

For remote backups the following paths are used:

•     /e/{volume}/backup/business/remote/{system}/(intern|obsolete|sites)/{site}

• volume - as described above

• system' - the hostname of the system when the original backup data is stored

• intern|obsolete|sites - as described above

• site - as described above
