Therefore, always create a full backup of each of your data stores after you upgrade ArcGIS Data Store. Due to changes in the underlying storage mechanisms and in ArcGIS software, the data store backups you create with older ArcGIS Data Store versions cannot be used to restore data to newer ArcGIS Data Store versions.You can add multiple machines to your tile cache and spatiotemporal big data stores. If you require that your hosted feature, spatiotemporal, and scene layers continue to be available even if a single ArcGIS Data Store machine fails, add a machine to each of your data stores to make them highly available. ArcGIS Data Store backups help you recover data lost if the ArcGIS Data Store machine fails or data gets corrupted.You'll still need to create separate backups of the user-managed data stores you register with the GIS Server site and the spatiotemporal big data store. See ArcGIS Enterprise backups for more information on using this tool. When you use the webgisdr tool, a backup is also created of your portal, hosting server, and federated servers. If you use a relational or tile cache data store (or both), you could use the webgisdr tool installed with Portal for ArcGIS to create a backup. You must create backups of those components separately. Backup files do not maintain a backup of the GIS Server site, your portal, or user-managed data stores you register with the GIS Server site. ArcGIS Data Store backup files only contain the relational, graph, tile cache, or spatiotemporal big data stores.Therefore, you need to store your backup files on a different server than your data store and, if possible, in a different physical location than your data store. If your backup is on the server that is destroyed in a flood, you cannot recover your data. Backups allow you to recover your data if a disaster occurs, such as when your server fails or floodwaters destroy your server.Keep the following in mind when implementing a backup and recovery strategy for your data stores: Read the ArcGIS Data Store backup considerations, then use the information in the remaining sections to configure and manage ArcGIS Data Store backups. If you create backups of your data stores and place them in a safe location, you can set up a new ArcGIS Data Store, access your backup files, and restore the data if for any reason your data store crashes and cannot be restarted. You need backups to recover your data in the event of a disaster such as data corruption or data store failure. ArcGIS Data Store backup considerations.
