Configure Share Settings
Topic
This article describes the Configure Share Settings options for Network Attached Storage (NAS) and iSCSI shares.
Environment
- Datto SIRIS
- Datto ALTO
- Datto NAS
Description
Datto Business Continuity & Disaster Recovery (BCDR) appliances can take point-in-time snapshots of the onboard NAS shares that they host and the external NAS shares they protect. To configure the share snapshot settings for your Datto appliance, perform the following steps:
- Access the device GUI.
- Click the File Share tab.
- Choose the share that you want to configure.
- Click Configure Share Settings.
Configuration Settings for NAS Shares
These configuration settings on the device are unique to NAS shares:
This option lets you make a share available globally or limit access. If you set the share to private, you must assign designated users.
NOTE Making a private share public will remove existing assigned users. If you set the share to private again, you must reassign the private users.
NOTE If you recieve an error when attempting to access a public share path, it may be due to Windows security policy settings for SMB. You may need to adjust group policy settings. See Guest access in SMB2 and SMB3 disabled by default in Windows (external link)
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 access. It 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. Admin access provides full root privileges (read, write and edit).
- To remove a user, click the Remove button next to the name of the user whose access you would like to remove.
- 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
Configuration Settings for iSCSI Shares
This configuration setting on the device is unique to iSCSI shares:
Snapshot settings
The snapshot settings are the same for both NAS and iSCSI shares.
Sync
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.
NOTE Pausing backups for an agent or share will not suspend billing for it. To modify your billing plan, contact your Datto Sales Executive.
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.
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.
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.
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.
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
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 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.
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
Clicking the Force Retention button immediately applies the device's retention policies for the share to its local backups. Learn more here.
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.
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.
