StoragePoint 6.2 - Reference Guide

Large File Support

SharePoint does not support the uploading of files greater than 2GB, or in some cases, 10 GB in size. Web Applications also have upload size limits. In SharePoint 2010 and newer, Metalogix StoragePoint has a feature that allows a custom upload interface to circumvent this limitation, if the Document Library is in the scope of an active StoragePoint profile. By dragging the file to the custom upload page, the document is moved to the endpoint, and a link (aspx file) is placed in the document library to access that file. The link will have a content type of ‘StoragePoint Document Link’. The BLOB will be externalized to the endpoint.

If for whatever reason StoragePoint is uninstalled, these large file uploads will no longer be available, because the endpoint is no longer available.

Administrators should ALSO know:

·StoragePoint must be present to allow for continued management of Large File content through SharePoint.

·Large File Support can be used with any of the StoragePoint-supported adapters.

·System Cache using the File System adapter is required to enable Large File Support.

·On the Unused BLOB Cleanup timer job, large files are not included by default, but this can be configured for the timer job.

·Bulk Migration operations will move Large File content across endpoints.

·Bulk Recall does not process Large File Content.

·Archiving will only move the .aspx files to the archive endpoint.

·It is recommended that the information in the Large File Upload section of the Administration Guide, or this supplement, be shared with end users if this feature is being enabled.

·Use of the large file upload feature requires at a minimum, the View Application Pages and Add Item permissions. When adding a custom permission level, Add Item will also automatically enable View Items, View Pages, and Open. These permissions are included with the default permissions of "Contribute" and higher. This is important to note if using custom security groups or breaking inheritance with security on lists or libraries.

·Large File Uploads are not compatible with any type of migration within SharePoint or from one farm to another. However, the actual large files can be uploaded from the endpoint, in the destination, since they are complete files.

Users should know:

·A user with the ability to edit document properties should not change the content type from ‘StoragePoint Document Link’.

·The aspx file will not be subject to metadata requirements normally placed on a document content type; there can be list data fields, but changing the content type to get those fields is not supported.

·Open or download can only be performed by clicking on the name of the document.

·Previous versions can only be accessed from the Large File Details Download link.

·The option to ‘download a copy’ is not supported.

·Office Web Applications are not supported.

·The file does not need to be large to use this interface, but files smaller than the upload limit for the web application  will not generate a link; they will be externalized to the endpoint like a regular upload.

·The recommended maximum number of files to be used with the Large File Upload interface is 100.

Enabling Large File Support

To enable large file support, select ‘yes’ on the dropdown, on the General Settings page. Large file support will be enabled on any Document Libraries under the scope of an active storage profile.

System Cache, using File System Adapter, is required to enable Large File Support. There will be a link available to edit System Cache if it is not already created.
