Granular restores skip versioned documents or files that are checked out
The following known issues relate to the restore of a document or a file that is enabled for versioning and is checked out at the time of backup:
For SharePoint 2010, the granular restore of such documents or files is skipped. The restore fails with the error: "Additions to this website have been blocked."
For SharePoint 2016, an additional version is present after restore. If the parent list contains a column that has a validation formula that might fail, the restore job might fail but the file content and other valid metadata are restored. The "checked-out" tag is also removed from the item.
To work around this issue, you can restore a checked-out item and its versions by selecting a list as the restore target. However, note that in this case, the "checked-out" tag is removed from the item. For more information, refer to the NetBackup for Microsoft SharePoint Server Administrator's Guide.
