The following items should be backed up to ensure that App Volumes can be recovered in the event of a disaster or other scenario:
- App Volumes Manager servers appliances
- AppStacks can be backed up from and restored to anywhere; what is most important is getting a reliable backup
- App Volumes Writable Volumes, including their underlying storage configuration if possible
- App Volumes Manager server appliance custom SSL certificates (if used)
VMware engineers have developed a utility that can be used to back up AppStacks and Writable Volumes. While the App Volumes Backup Utility (https://labs.vmware.com/flings/app-volumes-backup-utility) is not an official component of App Volumes, and offers no formal support, it may be useful for smaller environments that require a simple process for backing up critical App Volumes files.
