The Enterprise Vault Storage Verification and Repair Tool (EVSVR) is unable to repair (DeleteSurplusReferences) pre-8.0 Collected items that return "Sharer not found".
When performing a Verify, using EVSVR, against an affected location, items in this scenario will return <Sharer not found>.
Cause of <Sharer not Found>:
In EV 2007 and older, Single Instance Storage (SIS) was available only at the partition level. When sharing occurred between multiple whole items, each subsequent item stored would update the original file with the 'Sharer information'. If a disaster recovery occurred on storage, these additional Sharer references may no longer be present in the restored version of these files.
If it is necessary to repair these discrepancies prior to a released fix, please open a Support ticket for further assistance.
Symantec Corporation has acknowledged that the above-mentioned issue is present in the version(s) of the product(s) referenced in this article.
This issue only affects environments where a disaster recovery occurred in versions prior to Enterprise Vault (EV) 8.0 and where Collections were also enabled.
