PowerProtect Data Manager 19.14 Network-Attached Storage User Guide
Files with restricted permissions
If you use limited-privilege credentials to back up files without permissions for groups and owners, additional action is required before you add the NAS appliance or share to PowerProtect Data Manager. For example, files with 500, 600, and 700 permissions. Complete one of the following sections, as applicable.
Without this action, appliance backups are complete with an exception, where some files are skipped. The job details in the user interface contain the count of folders and files that are skipped during the protection. The backup logs contain detailed information on the number of skipped elements and the reason for skipping the files/folders.
PowerScale appliance
On the NAS appliance, add the NAS protection engine and PowerProtect Data Manager by hostname, FQDN, or IP address as clients, root clients, and read/write clients to the NFS export for the share. Enable mount access to subdirectories.
The PowerScale OneFS Web Administration Guide and PowerScale OneFS CLI Administration Guide provide more information about clients, modifying NFS exports, and adding a client to an NFS export. The Add NAS wizard contains a reminder for this step.
NAS shares
Add the NAS protection engine by hostname, FQDN, or IP address as a client of the NAS server to ensure that the NAS agent can read these files with restricted permissions. Because NAS server platforms can vary significantly, consult the documentation for your NAS server for instructions.
