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 NetBackup for 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.
