This article describes the process to create a new share on a Datto NAS device.
First, log in to the Remote Web interface for the device.
Go to the Shares page, and click Add a New Share on the top right hand side.
Figure 1 - Creating a share
Enter a name for your share.
Choose the type of share you wish to create. To help you decide between iSCSI and NAS, see the article What's the difference between iSCSI and NAS shares? As a rule, if an application can store files and directory on your C: drive, it can use a NAS share.
In the Configure section, you can create a new configuration profile or use an existing one.
When you are ready to move on, click Next.
The next page differs based on the kind of share you chose. See the relevant section below.
NAS Share Settings
For a NAS share, you will see the NAS Share Settings page, as shown in Figure 2.

Choose whether you want the share to be public or private.
Then, choose whether you want to enable write access for all users.
Next, choose the users to whom you want to give access to the share. This list is populated with users that you've created on the Datto NAS device. If this Datto NAS is connected to a Windows domain, you will see a list of the domain users.
The Other Options allow you to enable FTP, NFS, or AFP for the share. If you choose nothing, the default connection is through Samba.
Click Next when you are ready to move on.
iSCSI Share Settings
For an iSCSI share, you will see the page as shown in Figure 3.
Figure 3 - iSCSI Share Settings
Set the share size and block size for your share. Keep in mind that you cannot change the size of an iSCSI share once it is created. We recommend that you use the largest size you think you'll need.
You can enable CHAP Authentication here, but is not necessary. Usually, it is used for connection through a VPN to an iSCSI target. For more information, see CHAP.
When you have selected your settings, click Next.
Snapshot Schedules and Retention Settings
Whether you're creating an iSCSI or NAS share, you will see Snapshot Schedules page. See Figure 4.
Figure 4 - Snapshot Schedules
Set the interval and schedule at which the Datto will take snapshots of the NAS or iSCSI Share.
Click Next, and you will see the Retention Settings page, as shown in Figure 5.
Figure 5 - Share Retention Settings
Configure the necessary retention. This is an important step because it dictates how much local (and offsite) storage the device will use. Figure 5 shows the Datto-recommended retention settings. For more information about retention, see the article Understanding the Retention Process.
If you intend to use the share as a repository for a third-party backup solution, then we recommend that you set tighter retention settings. This is because this repository will fill the device faster than if it is used as a file server for end users.
Click Next when completed. You will see the message as shown in Figure 6.
