Issue



The following warning event is reported when attempting to retrieve a file that has previously been migrated to secondary storage using Enterprise Vault collection and migration feature:


Error



Event ID 20552

Error downloading file: ..., Url: ... 

Reason: The archived item is being retrieved from a slow or busy device and a timeout has occurred.

Cause



This occurs when the time taken to retrieve the file exceeds the time specified in the setting User wait timeout, which is in vault store partition properties. In particular, this may occur when retrieving very large files.


Solution



User wait timeout specifies the number of seconds that Enterprise Vault users wait for migrated file retrieval requests before timing out. The default value is 40 seconds. The requested file remains in the retrieval queue. Retrying later can usually resolve the issue.

If these warnings are reported frequently, it may be because the backup storage devices are fully utilized performing backups or restores, or are slow to load or read, or both. In this case you may want to increase the timeout value. You can configure the User wait timeout setting on the Advanced tab of vault store partition properties.
