Introduction

This article outlines the side-effects of having antivirus scanning active in the Staging Area during migration.

Overview

It is recommended to exclude virus scanner activity from Staging Area during migration.
In virus scanners there are usually options to:

  • Exclude files/folders
  • Exclude processes from ‘in memory scanning’

‘In memory scanning’ is not available in all antivirus scanners. In those that do in memory scanning, following processes might be excluded:

  • EV processes (if the source is EV)
  • Archive Shuttle processes on that EV source server

 

Details

If an antivirus scanning is active the following may be observed:

  • Significantly slower export
  • Significantly slower import

There may also be the specific errors during:

  • export
    • Files being locked errors
    • Denied access to the export folder of Staging Area. See an example below:

  • import
    • Item not found errors. This kind of errors can cause the re-export of  ‘missing’ files (can be overwritten in the System Configuration).
    • Hash failures/Chain of Custody errors. The antivirus product may change the files on disk, which leads to hash checking failures during the import (which leads to items being re-exported).
