The DEDUPREQUIRESBACKUP server option is set to YES. If the value of this option is YES (the default), files within a deduplicated storage pool must be backed up to a non-deduplicated copy storage pool before the files can be moved.
The operation skips the files without copies and continues the operation.
Ensure that all files in the primary storage pool are backed up to a non-deduplicated copy storage pool. You can also change the value of the DEDUPREQUIRESBACKUP server option to NO. However, doing so can result in unrecoverable data loss if a data-integrity error occurs. As a best practice, do not change the default.
