BackupBuddy Multisite: Introduction

From IThemes Codex
Jump to: navigation, search

Important: BackupBuddy Multisite functionality is EXPERIMENTAL and NOT officially supported. Multiple issues are known. Usage of it is at your own risk and should not be relied upon. Standalone WordPress sites are suggested. You may use the "Export" feature to export your subsites into standalone WordPress sites. Not all Standalone features are available for Multisite installations. Please carefully review the features, differences and limitations so that you are aware of them and are sure it will meet your needs.


You must add the following line to your wp-config.php to activate these experimental features:

define( 'PB_BACKUPBUDDY_MULTISITE_EXPERIMENT', true );

Backup entire Multisite Network

  • Limitations:
    • As a Network can contain many subsites, each subsite increases the amount of time needed to perform a backup, especially if the sites are large. This can demand more server resources or more PHP runtime. Most shared hosting does not permit increasing these resources so BackupBuddy may not be able to finish backups under these conditions. If you have access to modify these settings, Maximum PHP runtime is a key setting to increase as needed.
    • WordPress 3.5 Multisite has introduced multiple problems with site imports related with both file uploads and user imports. Some workarounds: http://ithemes.com/forum/topic/37186-backupbuddy-ms-import-not-working-on-wp-35-multisite/

Restore entire Multisite Network (same server & URLs)

  • Limitation: As a Network can contain many subsites, each subsite increases the amount of time needed to perform a restore, especially if the sites are large. This can demand more server resources or more PHP runtime. Most shared hosting does not permit increasing these resources so BackupBuddy may not be able to finish restores under these conditions. If you have access to modify these settings, Maximum PHP runtime is a key setting to increase as needed.

Migrate entire Multisite Network (different server or URLs)

  • You cannot migrate a Network to a new URL. This is not supported.

Export a subsite from the Network

  • Exported subsites may be imported back into the same network (AKA Duplicated), imported into another Network, or restored as a standalone WordPress site using the importbuddy.php tool.
    • Limitation: The main Network [sub]site cannot be exported as it is tied to the Network. It is still included in the main Network backup however.
  • Import an exported subsite into the Network
    • No known limitations beyond those of normal BackupBuddy.
  • Import a backed up standalone site into the Network
    • No known limitations beyond those of normal BackupBuddy.
  • Restore or Migrate an exported subsite as a standalone site
    • No known limitations beyond those of normal BackupBuddy.

WordPress Multisite Domain Mapping and BackupBuddy Multisite

Domain mapping was confirmed by customers to work in pre-v3.0 BackupBuddy versions. It has not been officially tested with > 3.0 versions. Customer reports of success/failure are welcomed. Note: Some functionality has changed and improved since this video was made. It is not the latest version.
