Creating incremental backups at different sites in a multi-site environment may prevent data from being restored. As a best practice, perform all backup and restore operations at a single site in a multi-site environment.
The options available on the second screen of the Backup and Restore Wizard depend on whether Backup or Restore was selected on the first screen.
Incremental Backup backs up only new or modified files in the file store as well as any changes to user accounts. Files and libraries that have not changed are not included in an incremental backup. Because standard libraries do not change, they are also not included in a incremental backup.
Incremental backups can only be restored in chronological order. An older incremental backup cannot be restored once a newer incremental backup has been restored. Specify the location to store the backed up data. To browse for a location, click ... and then locate a directory using the file browser. An incremental backup folder is named using the same naming convention as full backups, with the addition of _INCxx, where xx indicates the increment number. The destination folder for an incremental backup does not need to be the same as the folder containing the full backup. See Back Up or Restore a Vault for more details.
If you choose to restore, you should perform the restore starting with Incremental Backup. As long as all incremental and full backups are under the same top-level folder, the restore process will automatically restore Incremental Backups in reverse order and the Full Backup last. The restore process, which includes restoring incremental backups, should always start from the latest incremental backup in the series but choosing Full Restore option in the Backup and Restore wizard.
