GRT backup fails for SharePoint if the SharePoint database object path exceeds the Windows maximum path limit
A Granular Recovery Technology (GRT) backup fails for SharePoint if the SharePoint database object path exceeds the Windows maximum path limit.
During GRT backup, SharePoint database objects are temporarily stored as files within a folder hierarchy. This folder name consists of the SQL Server host name, Backup image ID, and Content Database name within the NetBackup temporary directory path. Together this combination should not exceed the Windows path length limitation. For more details, refer to the following Microsoft article:

If the Windows path length limitation is exceeded, then the result can be a failure to capture the backup artifacts for GRT for SharePoint.
Workaround: Ensure that the content database name along with the other parameters mentioned above does not exceed the Windows maximum path limit.
