Virtual portal settings are default settings that apply to all virtual portals. Global settings can be overridden for each virtual portal from that virtual portal's administration interface.

Support Email – The email address to which support requests are sent.

Android – The URL of the Android app store.

Delete files of zero quota users after – The storage folders of customers who have no quota (for example, customers with expired trial accounts) are deleted automatically after a certain number of days. Enabling this option helps free storage space. A notification is sent to the customer prior to deletion, prompting the customer to purchase cloud storage in order to avoid the scheduled deletion of their files. Storage folders of over-quota users with a non-zero quota are not deleted. The default value is 14 days.

Invitation to register is valid for:... days – The validity period, in days, for registration invitations sent to users by team portal administrators. If a user has not registered for the service after the number of days specified in this field, the invitation expires.

Enable vouchers support – Enable the use of vouchers in the CTERA Portal. If this option is cleared, the Provisioning > Vouchers menu item is not displayed in the reseller portal's menu.

Enable Sharing of Personal Folders – Enable team portal members to share personal folders with other team portal members.

Allow collaborators to re-share content – Enable team portal members who are listed as collaborators for a file or folder to re-share the file or folder to other users.

Allow collaborators to leave shared folders – Enable team portal members to leave a folder that they have been listed as a collaborator. Once a member leaves a shared folder, they have no access to the folder unless they are re-added as a collaborator.

Allow users to request team projects with independent quota – Enable team portal members to request a team project, so that storage for the project does not use personal storage.

Use encryption – Data in newly created folder groups is stored in encrypted format by default.

Deduplication Method – Whether to use the average block size or a fixed block size for deduplication. The options in the window change depending on what is selected to either Average Block Size or Fixed Block Size. Only use Fixed Block Size if many of the folder groups that large files where deduplication is not common, such as media files.

Average Block Size/Fixed Block Size – The average block size used by the folder group or the fixed block size used by the folder group. The default value when set to Average Block Size is 512KB and 4MB when set to Fixed Block Size. CTERA Portal deduplication splits each stored file into blocks. Increasing the Average Block Size or Fixed Block Size causes the files to be split into larger chunks before storage, and results in increased read/write throughput at the cost of a reduced deduplication ratio. Increased block size is useful for workloads that require high performance, as well as for those that do not gain greatly from deduplication. For example, where the stored files consist mostly of videos, images, and music files that are not frequently modified. Decreasing the average block size can result in better deduplication, since the portal can better identify finer-grained duplicate data.

Average Map File Size – The average map file size used by new folder groups.

CTERA Portal uses file maps to keep track of the blocks each file is made of. The Average Map File Size represents the maximum size of file that will be represented using a single file map object. For example, if the average map file size is set to 100MB, files of up to approximately 100MB will have one file map, files of up to approximately 200MB will have two file maps, and so on. Reducing the average map file size causes more file maps to be created per file. This may result in smoother streaming of files; however, it will also result in some extra overhead for creating, indexing, and fetching the additional file maps. The default value is 640,000KB.

Interface Language – The default language for new users. This language can be overridden by end users in the End User Portal. The following languages are supported: English, French, German, Hebrew, Italian, Polish, Spanish, Portuguese, Brazilian Portuguese and Traditional Chinese.

By default, public link is valid for – The number of days for which public link to a folder is valid.

None – No user authentication is applied.

Email – The invitation recipient receives a time limited authenticated link to the file or folder. On every access, a new 6 digit passcode challenge is sent to the recipient by email. The recipient must enter the passcode before accessing the file or folder. This ensures that the invitation is not usable in case the invitation link is accidentally forwarded to another person, or posted on a public website.

SMS – The invitation recipient receives a time limited authenticated link to the file or folder. On every access, a new 6 digit passcode challenge is sent to the recipient by text message. The recipient must enter the passcode before accessing the file or folder. This ensures that the invitation is not usable in case the invitation link is accidentally forwarded to another person, or posted on a public website.

Display "Remember me on this browser" option – When checked, a Remember me checkbox is displayed in the user interface when the user accesses the file or folder via the link and the user can opt to be remembered on the computer. In this case, a passcode is not sent every time the user wants to access the file or folder. If this option is not checked, a Remember me checkbox is not displayed and the users receive a passcode to their email or SMS on every access to the file or folder.

Office 365 is a cloud-based office suite offered by Microsoft, which allows users to create and edit files using lightweight, web browser-based versions of Microsoft Office applications, such as Word, Excel, and PowerPoint.

Other web sites also include instructions to install the Office Online Server (OOS), with graphics to help you, for example, https://www.getfilecloud.com/supportdocs/display/cloud/Installing+Office+Online+Server+on+Windows+2012+R2+Server to install OOS on a Windows 2012 R2 Server.

If required, import a certificate, via the certmgr.msc application, to Personal > Certificates.

If you have problems and need to refer to the OOS logs, they are located by default on the OOS server under C:\ProgramData\Microsoft\OfficeWebApps\Data\Logs\ULS.

To enable Microsoft Office Online to work with a CTERA Portal, an initialization phase is required. In this phase CTERA Portal initiates a WOPI discovery call to the Office Online server to identify Office Online capabilities and how to initialize Office Online applications within the site. CTERA Portal uses the discovery XML to determine how to interact with Office Online by retrieving a list of application names and the corresponding URLs.

When first connecting the CTERA Portal to Office Online, CTERA Portal verifies that all requests will come from Office Online, using the Proof keys concept according to Microsoft best practices. For more information see https://wopi.readthedocs.io/en/latest/scenarios/proofkeys.html#proof-keys.

Office Online signs every WOPI request with a private key. The corresponding public key is available in the proof-key element in the WOPI discovery XML. The signature is sent with every request in the X-WOPI-Proof and X-WOPI-ProofOld HTTP headers.

When a user browses to a folder in the CTERA Portal, all the file names under this folder are returned to the end user’s browser together with:

The CTERA Portal receives the request to browse a folder from a Microsoft service and not directly from the user PC. All requests are directed via th secure port 443.

When an end user requests to open an Office file in their browser, the browser submits a request to Office Online to open the file. Each requested file has a file ID and the unique access token. These are used by Office Online to request the file from the CTERA Portal and by the CTERA Portal to verify the request and then return the file back to Office Online.

Once the file has been verified, it is locked and passed to the user for editing. During the editing, the file is periodically saved to the CTERA Portal. If more than one user edits the file at the same time, co-authoring, the file is unlocked and relocked by Office Online to manage the edits from multiple users. At the end of the editing session the file is unlocked.

Customize the watermark and footnote added to shared files restricted to previewing.

Text – The text to be displayed diagonally each page of a file restricted to previewing only. The following variables are supported in the text field: ${recipient}, ${date} and ${company}.

Text – The text to be displayed at the bottom of each page of a file restricted to previewing only. The following variables are supported in the text field: ${recipient}, ${date} and ${company}.

Use HTTPS for remote access – Use HTTPS for remotely accessing devices, using the remote access service.

Send CTTP keepalive messages every – Prevent proxy or load balancer servers from preemptively terminating connection between a CTERA Agent and the CTERA Portal. This may be relevant if the CTERA Agent is configured to use a proxy server and there are connectivity problems during Cloud Backup or Cloud Sync. This is because some proxy servers and load balancers are configured to close open connections that are not transferring any data after a certain amount of time, thereby causing connectivity problems.

In the field provided, specify an interval, in seconds, smaller than the timeout value configured on the proxy or load balancer server.
