i dont know if it's exactly what you're looking for but there is a reg key called FileDownloadTimeOut.
from the Registry_Values.pdf that comes with EV:
FileDownloadTimeOut
On a 32-bit installation of Windows:
HKEY_LOCAL_MACHINE
\SOFTWARE
\KVS
\Enterprise Vault
\FSARestore
On a 64-bit installation of Windows:
HKEY_LOCAL_MACHINE
\SOFTWARE
\Wow6432Node
\KVS
\Enterprise Vault
\FSARestore
Location
Content DWORD.
FileDownloadTimeOut lets you change the placeholder recall
mechanism of the FSAUtility -t and -b options from asynchronous to
synchronous, and to specify a timeout, in minutes, for the synchronous
recall of each file.
If FileDownloadTimeOut is set to 0, recall is asynchronous.
If set to any value greater than 0, file recalls happen synchronously
with a timeout of the specified minutes. If the recall operation does not
complete within the specified timeout, FSAUtility moves on to recall the
next file.
For example, if you set the value to 30, FSAUtility adds a file to the
queue for file recall and waits for 30 minutes for the file recall to
complete. If the file is not recalled in 30 minutes, the recall operation
runs in the background, and FSAUtility puts the next file in the queue.
Set this registry value on the computer on which you run FSAUtility.
This registry value does not exist by default. If FileDownloadTimeOut
does not exist, FSAUtility -t and -b options recall files asynchronously.
