Pass-through recall for placeholder shortcuts with File System Archiving
For Windows and NetApp file servers, you can configure Enterprise Vault to perform pass-through recall for placeholder shortcuts. Enterprise Vault then passes the data directly through to the calling application on receipt of a read request for a placeholder. Enterprise Vault recalls the file to the file server, subject to permissions, only if the calling application makes a write request. For example, this is the case if the application requires a writeable file, or the user attempts to save changes to a file.
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 where 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. For Windows file servers, you can enable or disable pass-through recall for each file server volume.
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 file servers, the disk cache is located on the Enterprise Vault server.
Note the following:
Some applications such as Excel always recall to disk even when pass-through recall is enabled.
For Dell EMC Celerra/VNX file servers, Enterprise Vault supports the Celerra/VNX pass-through facility.
For NetApp file servers, the pass-through recall feature works only with read-only file systems. Pass-through recall is ignored for read-write file systems.
There is a setting "Delete archived file when placeholder is deleted" on the Shortcuts tab of volume policy properties and folder policy properties. That setting is ignored on Windows file server volumes if pass-through recall is enabled on the volume.
