NetBackup™ NAS Administrator's Guide

Restore from NAS array volume fails with the status: 174 Media manager - system error occurred.

Explanation:

This error occurs during granular restoration of a specific combination of files and directories that were backed up from a NAS array.

  • For NetBackup version 10.4, this issue occurs only for multi-stream restores.

  • For NetBackup version 10.5 and above, this issue occurs for both single-stream and multi-stream restores.

Workaround:

Do any of the following:

  • For NetBackup version 10.4, use a single stream for the restore job.

  • For NetBackup version 10.5 and above, do only one selection at a time, in the restore selection, like a volume, a directory, or individual file(s).
