Veritas NetBackup™ for Hadoop Administrator's Guide

Backup operation fails with error 6647

Backup operation fails with error 6647 wherein the following error is displayed:

Unable to create or access a directory or a path. (6647)

This error is encountered in one of the following scenarios:

  • Directory is not snapshot-enabled.

  • Policy is configured to take snapshot of the root folder as backup selection, whereas one of the child folder is already snapshot-enabled.

  • Policy is configured to take snapshot of a child folder as backup selection, whereas one of the parent folder is already snapshot-enabled.

  • Policy is configured to take snapshot of a file as backup selection

Workaround:

Nested snapshot-enabled directories are not allowed in Hadoop. If the parent directory is already a snapshot-enabled, than any other child directory under the parent directory cannot be enabled for snapshot. For backup selection in Bigdata policy type, only snapshot-enabled directory must be selected for backup and any other child directories must not be selected.
