Error description
In the following snapdiff backup statistics, Total number of objects inspected: 4 Total number of objects backed up: 5 928 Total number of objects updated: 0 Total number of objects rebound: 0 Total number of objects deleted: 0 Total number of objects expired: 917 Total number of objects failed: 0 Total number of objects encrypted: 0 Total snapshot difference objects: 38 678 Total number of subfile objects: 0 Total number of objects grew: 0 Total number of retries: 0 Total number of bytes inspected: 648 B Total number of bytes transferred: 7,54 GB Data transfer time: 1 092,60 sec Network data transfer rate: 7 239,62 KB/sec Aggregate data transfer rate: 1 380,40 KB/sec Objects compressed by: 0% Total data reduction ratio: 0,00% Subfile objects reduced by: 0% Elapsed processing time: 01:35:30 We see this line : "Total snapshot difference objects: 38 678" which means the client saw 38678 objects that changed as reported by the NetApp filer snapdiff feature. This number should be equal to what the Netapp "apitest" tool (available from NetApp SDK) would report as changed objects between the same filer volume snapshots (Base and differences snapshots) as used by the backup process. In reality, this is not the case. "Total snapshot difference objects" might report more objects than the "apitest" tool when directories containing more subdirectories and files are created. This is a cosmetic issue only and does not affect backup consistency.

Problem conclusion
The issue in the calculation of snapshot difference objects in the case of a newly created or just fully removed folder has been fixed. Note that the calculation does not include objects having the change type 'inode_modification' whose contents have not been changed. For information about the 'inode_modification' see the NetApp documentation. You can use the auditlogging option to generate an audit log that contains an entry for each file that is processed during the snapshot differential backup.
