Configuration Settings for NAS Shares

These configuration settings on the device are unique to NAS shares:

Make Share Public/Private

This option lets you make a share available globally or limit access. If you set the share to private, you must assign designated users.

Making a private share public will remove existing assigned users. If you set the share to private again, you must reassign the private users.

Add User to Share

This option provides you with the ability to give users root access to the share.

1. To add a user, type in the username and click the Add user button.

2. Check the Add as admin box to grant the user root access to the share.

Manage Share Users

Manage Share Users provides management options for users and groups assigned to the share. From this card, you can grant users root access to the share, and you can remove their accessIt also gives you the ability to remove users.

  • To add a new admin and grant them root share access, click the Grant admin access button next to the user who you would like to promote.
  • To remove a user, click the Remove button next to the name of the user whose access you would like to remove.

Other Share Options

  • Enable write access for all users: This option lets you give all users of the share permission to write to the files and folders within it
  • Apple Filing Protocol (AFP): Allows users with Mac OSX to access and use the share; this option also allows Apple's Time Machine to back up files and folders within the share
  • Network File System (NFS): Enabling this option enables endpoint machines to access and write to the share as though it were a local volume; for more information about NFS, see Microsoft's Network File System (external link)
  • Secure File Transfer Protocol (SFTP): Enables secure transmission of files and folders using SFTP

Snapshot settings

The snapshot settings are the same for both NAS and iSCSI shares. 

Sync

Pause Snapshots

The Pause Snapshots setting allows you to stop local backups for the selected share or all shares on the device. When the Enabled setting is selected, backups for the share will run. When the Paused setting is selected, backups for the share will not run. Preferences for snapshot interval and snapshot schedule will preserve when pausing backups for shares. 

Pausing backups for an agent or share will not suspend billing for it. To modify your billing plan, contact your Datto Sales Executive.

Pause Cloud Snapshots

The Pause Cloud Snapshots setting allows you to halt the replication of backups to the Datto Cloud for the selected share or all shares on the device. When the Enabled setting is selected, replication will run. When the Paused setting is selected, replication for the share will not run. Preferences for snapshot interval and snapshot schedule will preserve when pausing replication for shares.

NOTE: If your Datto appliance subscribes to SIRIS Private service, you will see the Pause Replication card instead.

Pause Replication

The Pause Replication setting allows you to halt the replication of backups to a target SIRIS for the selected share or all shares on the device. When the Enabled setting is selected, replication will run. When the Paused configuration is active, replication for the share will not run. Preferences for snapshot interval and snapshot schedule will preserve when pausing replication for shares.

NOTE: If your Datto appliance does not subscribe to SIRIS Private service, you will see the Pause Cloud Snapshots card instead.

Local Snapshot and Retention

The Local Snapshot and Retention Policy setting allows you to specify how often your Datto appliance should capture a local backup of the selected share or for all shares on the device, and how long those backups should retain on the Datto appliance.

Cloud Snapshot and Retention

The Cloud Snapshot and Retention Policy setting allows you to specify how often your Datto appliance should replicate local backups of the selected share or all shares on the device to the Datto Cloud, and how long those backups should retain on the offsite storage node.

NOTE: If your Datto appliance subscribes to SIRIS Private service, you will see the Replication and Retention Policy card instead.

Replication and Retention

The Replication and Retention Policy setting allows you to specify how often your Datto appliance should replicate local backups of the selected share or all shares on the device to a target SIRIS. It also enables you to designate how long those backups should retain on the target device.

NOTE: If your Datto appliance does not subscribe to SIRIS Private service, you will see the Cloud Snapshot and Retention Policy card instead.

Secure File Restore

The Secure File Restore feature allows you to require credentialed login to SMB shares created for File Restores. When activated, users will be prompted by the Datto appliance to enter the credentials of the account you select before they can access the restore. You can configure secure file restore access at a per-share or global level.

Reporting & Alerting

Growth Report

From the Growth Report card, you can subscribe to email reports which detail storage usage fluctuations for your appliance's protected shares. You can elect to receive reports daily, weekly, or monthly. When enrolling multiple email addresses, separate each entry with a comma.

Critical Error Alerts

The Critical Error Alerts setting allows you to specify one or more email addresses which should receive a notification when local snapshots for the selected share are no longer occurring and are unlikely or unable to resume. To enter multiple email addresses, separate each entry in the list with a comma.

Warning Notices

The Warning Notices setting allows you to specify one or more email addresses which should receive a notification when the selected share encounters an error condition where a warning state has occurred. For example, a single snapshot for the share may not have taken place, but future snapshots are likely to resume. To enter multiple email addresses, separate each entry in the list with a comma.

Log Digests

The Log Digests setting allows you to specify one or more email addresses which should receive a daily summary of the last 24 hours of activity for the selected share. To enter multiple email addresses, separate each entry in the list with a comma. Your Datto appliance sends logs at midnight (device time). Once you configure this setting, the first log digest will send after the next logging event occurs on your device.

Advanced

Force Retention

Clicking the Force Retention button immediately applies the device's retention policies for the share to its local backups. Learn more here.

Destroy Live Dataset

The Destroy Live Dataset option will stop any snapshots in progress for the selected share and delete its live disk images from the Datto appliance. It will leave the snapshot chain intact. Selecting this option will result in the share taking a new full backup, which will take up the space of a new full image on your Datto device. Only use this option if the protected share's disks have resized, or if the protected share's disk image is irreparably corrupt.

Change Connection Settings

NOTE: You will not see this option if the selected share is not an external share protected by NAS Guard.

The Change Connection Settings feature allows you to update the SMB address and connection credentials for the selected share. Use this feature if the address or the connection credentials of the production share have changed. To have your Datto appliance connect to the production share as a guest, check the Guest Access box.

Changing connection settings can help resolve One Or More Files Were Copied Unsuccessfully Due To Lack Of Permissions issues.
