From Dimension, you can manually run a task to back up the historical data in your Dimension database. The amount of time it takes to create a backup file depends on the amount of log data to be included in the backup. You can back up historical data in 24-hour increments. You can also run a task to restore the historical data from a backup file to your Dimension database.
Only users with Super Administrator credentials can back up and restore historical data to Dimension.
Before you can create a backup file, you must specify a directory where the backup files are saved. The backup directory location is specified in the Dimension System Settings > Configuration settings. For more information and instructions to specify the backup directory location, see Configure Remote Backup Settings.
You can monitor the progress of the backup or restore tasks from the Manage Tasks page.

Restore Historical Data
When you restore a backup file of historical data to your Dimension server database, the data in the backup file are added to the existing log files in your database. If the files you import do not increase the size of your Dimension server database to over 95% of the maximum database size, all of the existing and newly imported log files are maintained in the Dimension server database. If the log files you import increase the size of your Dimension server database to 95% of the maximum database size, the oldest log files are purged until the database size is reduced to under the maximum database size.
