Confluence 2 User Guide : Site Backup and Restore
This page last changed on Dec 27, 2006 by david.soul@atlassian.com.
By default, Confluence backs up all data and attachments once a day to a backup file. These files are called XML site backups, stored in the backups directory of Confluence home. You can also create XML site backups manually.
XML site backups are fine for most instances of Confluence. However, large instances of Confluence will find backups may become slow to create and use large amounts of disk space. Backups For Large InstancesXML site backups are unsuitable for instances of Confluence that contain hundreds of large pages, as XML backups take progressively longer to complete as the amount of text increases. Another issue with XML site backups is that Confluence instances with a gigabytes of attachments will consume disk space rapidly. This is because each site backup contains all content needed for a site restore. For example, if a 1 gig instance of Confluence is backed up daily, it will create 30 gig of backups per month if left unattended. When administering a large instance, you can reduce disk space by setting XML site backups to exclude attachments, then manually scheduling a backup of your attachments from the Confluence home directory or database. The backup manager can save space by saving changed files instead of all content.
Creation Delay is the time it takes to create an XML site backup minus attachments. Manual BackupsConfluence's attachment storage configuration can be set to store attachments in the Confluence home directory, or in the database.

If the performance hit is significant, you can switch to an external backup process for large instances. How can I reduce the space taken up by automatic backupsSwitch to a manual backup process according to the 'Backups For Large Instances' section of Site Backup and Restore, which will give you more control over disk usage. Can Confluence be restored from a backup minus attachments?Yes, as long as the attachments have been backed up are the same time. Refer to Site Backup and Restore.
