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.
Add a user to Share
This option lets you give users root access to the share.
- To add a user, type in the username and click the Add user button. Check the Add as admin box to grant the user root access to the share.
Manage share users and groups
This option lets you control which users and groups have root (admin) privileges for the share. It also lets you remove users.
- To add a new admin, enter the username or group name and click the Grant admin access button.
- To remove a user, enter the user or group name and click the Remove button.
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 also allows Apple's Time Machine to back up files and folders within the share.
- Network File System (NFS): Enabling this option allows 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.
Configuration settings for iSCSI shares
This configuration setting on the device is unique to iSCSI shares:
To set up CHAP authentication on the iSCSI share, click the Enable CHAP authentication checkbox, then click the Apply button.
The snapshot settings are the same for both NAS and iSCSI shares.
The Pause Snapshots setting allows you to stop local backups for the selected share or for 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 be preserved when pausing backups for shares.
Pause Cloud Snapshots
The Pause Cloud Snapshots setting allows you to replication of backups to the Datto Cloud for the selected share or for 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 be preserved when pausing replication for shares.
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 be retained 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 be retained on the offsite storage node.
Reporting & Alerting
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.
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 have been missed but future snapshots are likely to resume. To enter multiple email addresses, separate each entry in the list with a comma.
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. Logs are sent by your Datto appliance at midnight (device time). Once you configure this setting, the first log digest will be sent after the next logging event occurs on your device.
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 been resized or the protected share's disk image is irreparably corrupt.
Change Connection Settings
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.
