A NAS share may have multiple backup sets configured, with each backup set backing up a set of files and folders. With multiple backup sets, you can schedule backups when there is minimal network traffic and also perform backups of specific files and folders.
Credentials in NAS share
NAS shares integrate with the credential store. The credentials for manually added shares and automatically discovered shares are stored in the credential store. NAS credentials, once added, can be used for multiple NAS shares. Older shares continue to store the share credentials on the NAS proxy. If you have enabled the Use device credentials for auto-discovered shares setting while adding a NAS device, the automatically discovered shares will use the device credentials. The Credentials column in the NAS Shares page displays the status of credentials assigned to each share. Credentials only need to be assigned to SMB/CIFS shares. NFS shares do not require credentials.
The following table discusses the Credentials column value for NAS shares.
Credential status | Description |
N/A | This is an NFS share that does not need credentials. |
Device Credential | This share uses the NAS device credentials |
< credential > | This is the credential that has been assigned to the share and is stored in the credential store. |
Local | This credential is stored on the NAS proxy |
Assign | When the device is not set to use device credentials for share auto-discovery, and the auto-discovered share does not have an assigned credential. |

Error messages
Druva displays the following error message if you attempt to delete a NAS share without deleting the backup sets configured in the share.
📝 Note
Could not delete the NAS share as there are backup sets configured in it. To delete a NAS share, you must delete all the backup sets in it.
For any other error messages or internal errors, contact Druva Support.
Delete NAS share recovery points
If you are a cloud administrator, you can delete warm recovery points of NAS shares that you no longer require. If you are a group administrator, you can delete warm recovery points of NAS shares that belong to the administrative groups that you manage.
After you delete a recovery point, Druva purges the recovery point data from the warm storage, thus freeing up the storage space.
📝 Note
You cannot delete the most-recent recovery points of a NAS share. However, all recovery points get compacted according to the retention period defined in the backup policy.
