About pass-through recall for placeholder shortcuts
You can configure the pass-through recall of placeholder shortcuts on Windows file servers, and for read-only file systems on NetApp filers that run Data ONTAP 8.0 or later. For Dell EMC Celerra/VNX devices, Enterprise Vault supports the Celerra/VNX pass-through facility.
Note:
Due to a NetApp restriction, pass-through is not supported for Data ONTAP 8.2 C-Mode.
If pass-through recall is configured, then on receipt of a read request for a placeholder Enterprise Vault passes the data directly through to the calling application. Enterprise Vault recalls the file to the file server, subject to permissions, only if the calling application makes a write request: for example if the application requires a writeable file, or if the user attempts to save changes to a file.
Note:
Some applications such as Excel always recall to disk even when pass-through recall is enabled.
Pass-through recall can be useful in the following circumstances:
With placeholders on read-only file systems, such as snapshots. A normal placeholder recall to a read-only file system fails because Enterprise Vault cannot write the recalled file to the file system.
With Windows file servers when there is limited space on the file server, or when users have strict quotas for space usage. Recalled files normally occupy space on the target file system, and therefore count towards a user's space quota.
Pass-through recall uses a disk cache to reduce recall times for large files. For Windows file servers the disk cache is located on the file server. For NetApp filers the disk cache is located on the Enterprise Vault server.
For Windows file servers you can enable or disable pass-through recall for each target volume.
