Data Manager supports centralized protection for NAS assets, where all the stages of the protection policy are managed by Data Manager.
Note: Data Manager uses these credentials at the policy level for all shares unless otherwise specified at the asset level. The credentials provide snapshot creation and export permissions on the appliance and read/write access to the NAS shares.
If credentials are set at the protection policy level, all shares should use the same credentials for access. Otherwise, if individual asset credentials are set at the asset level, multiple assets use their respective credentials.
For more information about creating a protection policy for NAS protection, see the Dell PowerProtect Data Manager for Network Attached Storage User Guide at PowerProtect Data Manager Info Hub: Product Documents and Information on Dell Support.
Individual asset credentials can be set from the Data Manager UI.
Beginning with PowerProtect Data Manager 19.14, you can configure various asset-level parameters from the Data Manager UI.
To configure the parameters:
You can then configure these backup and job options:
The following table describes the behavior when both flags are selected, only one flag is selected, and when no flag is selected:
ContinueOnFileNameLenLimitReached | SkipFilesWithNameLenLimitReached | Expected behavior |
TRUE (default) | TRUE (default) | Backup continues and skips the files/folders with names >255 bytes. |
TRUE | FALSE | Backup continues and includes the files/folders with names >255 bytes. |
FALSE | FALSE | Backup fails when the files/folders with names >255 bytes are encountered in the share. |
FALSE | TRUE | Backup fails when the files/folders with names >255 bytes are encountered in the share. |
When a cancel request is made, the NAS proxy repeatedly sends a cancel request for a time period (around 25 minutes) in fixed intervals, after which the job is forcefully terminated, either at the Data Manager layer or at the NAS agent layer.
If the job has already completed but has failed to report back, a cancel request will be denied with a warning alert in the job summary, indicating the status of the job as shown in the following image.
When the Search Engine is installed, the Enable indexing for file search and restore option is available while creating the protection policy to enable indexing the NAS backups.
Beginning with PowerProtect Data Manager 19.12, you can continue the backup even if a data access denied or an ACL access denied failure is encountered on files. You can set these flags as shown here:
