Error while recalling or copying large numbers of archived items in Enterprise Vault (EV) for File System Archiving.
The remote storage service was not able to recall the file.
You can specify a maximum rate of recall on each computer that runs a Placeholder Service, thus controlling the rate at which an individual user can recall files. By doing this you also prevent any applications that do not honor the file system offline attribute from recalling all files that had been archived from a volume.
The default maximum rate is 20 recalls in 10 seconds. This recall limit applies to all users except, by default, members of the local Administrators group.
If the recall limit is exceeded, the application receives an Access Denied status. Just how this is displayed to the user depends on each individual application.
Modifying the following registry values on each computer running the Placeholder Service allows the defaults to be increased or decreased.
Note: For an x64 platform changes need to be made in following location: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\KVS\Enterprise Vault\FSA\PlaceholderService
RecallLimitMaxRecalls specifies the maximum number of items that a user is allowed to recall within the specified RecallLimitTimeInterval seconds. When this limit is reached, there is a additional wait of RecallLimitTimeInterval seconds before the count is reset.
- The initial value is 20.
- The effective values range from 0-99 (decimal), settings above 99 will result in the default value of 20 being used.
- The initial value is 10 (seconds).
- The lowest value EV will use is 1, values of up to 60 can be used (decimal)
While there is not a way to disable the recall limit entirely, you can render it effectively impotent by setting RecallLimitTimeInterval very low. Setting it to 1 means that it will only trigger the limit if it is reached in a single second; even with RecallLimitMaxRecalls at the default 20, this is unlikely to happen (20 files recalled in one second). On a very powerful system, you could increase RecallLimitMaxRecalls to 99 to make the limit even less likely to be reached (99 files recalled inside one second). This has been successfully tested recalling 1,000 files using RecallLimitTimeInterval = 1 and RecallLimitMaxRecalls = 20 (default).
BypassRecallLimitsForAdmins controls whether the recall limits apply to members of the local Administrators group on the server that is running the Placeholder Service. Setting to 1 will allow members of local admins to recall files without restriction.
Note: Once the registry changes are complete, restart the Enterprise Vault Placeholder Service for the changes to take effect.
