About incremental backup
NetBackup supports incremental backup for Cloud object store workloads. You can use incremental backup without enabling accelerator.
For Cloud object store workload, there are some metadata properties that do not alter the modification time for an object or blob. For example, the Tags
in Azure blobs. Even if you change these metadata properties, the corresponding objects are not considered for the next incremental backup. This may appear like loss of data during incremental backup.
For detailed list of metadata properties that do not alter modification time for an object or blob, refer to the respective cloud provider's documentation.
For incremental backups, if an object name has path style naming scheme, then for each path, an entry is added in NetBackup. If the object, which is represented by the end node of this path style naming, has not changed since last backup (either full or last incremental, based on incremental schedule used), then that object is not included in the next incremental backup. Because of this behavior, empty paths show up in the catalog and are rendered in the browse view of restore.
