PowerProtect Data Manager 19.10 Network Attached Storage User Guide

Unable to move backups to protection storage

Verify that there is sufficient free space on the protection storage system.

Unable to discover assets

If the first discovery succeeds and later discoveries fail, verify whether the asset credentials have changed. Update the credentials in PowerProtect Data Manager accordingly.

Consecutive incremental backups fail

Perform a manual full backup of the NAS asset. The PowerProtect Data Manager Administration and User Guide provides instructions.

Unable to back up share assets

Verify that the share address and path are valid and mountable. Adding a share does not verify that the share can be backed up.

Unable to back up a NAS appliance because of connectivity errors

You may receive error messages such as Unable to communicate with NAS appliance when the appliance does not respond as expected and backups may fail to start.

Verify that the NAS appliance is available. Verify connectivity between PowerProtect Data Manager, the protection engine, and the NAS appliance. Verify the appliance and management credentials and, if required, update the stored appliance credentials.

For Isilon/PowerScale appliances and protection policies with large numbers of NAS assets, the resulting quantity of REST API calls may exceed the appliance API rate limits. When this happens, the appliance API becomes temporarily unavailable. To work around this limit, move some NAS assets to different protection policies or retry the failed backups.

Unable to back up CIFS shares on PowerScale/Isilon appliances after updating PowerProtect Data Manager

Perform a manual full backup and then verify that subsequent backups succeed.
