Event ID 6621 error related to PlaceHolds processing thrown into the Enterprise Vault (EV) Event Log
Enterprise Vault (EV) Discovery Accelerator (DA) has the capability to place Legal Holds on Savesets in the EV Vault Store databases for messages found and accepted in a DA search. This process normally works in the background until all accepted search hits for the appropriate DA Case are on Legal Hold. The EV Vault Store databases are controlled by the EV Storage Service one or more EV servers. When the EV Vault Store and EV Indexes need to be backed up, it is recommended that the EV Storage Service be placed into Read Only Mode or into Backup Mode.
Error Message
If the EV Storage Service is placed into Read Only or Backup Mode while the DA processing is attempting to place Savesets on Legal Hold, Event ID 6621 will be thrown into the Enterprise Vault Event Log on the EV Storage Service Server as follows:
