The NetBackup Administrator's Guide for Windows, Volume I details that files and directories with path lengths greater than 1023 are automatically excluded from backups. For MAPI mailbox backups and for GRT-enabled backups, the path length limit applies to individual mailbox folders and messages. When a legacy mailbox backup encounters an item that exceeds the limit, the backup job reports a final status of 1. This status indicates that some items were not backed up, and the job details tell you which items were skipped. For granular backups NetBackup checks the pathname length limit and reports exceptions, during browsing and restoring of the granular backup image. It logs the pathnames that exceed the limit in the unified logging ncflbc or ncfgre logs. Then it reports the items that were skipped during restore to the View Status window.
