About Enterprise Vault quiescence before a backup
To back up an Open partition or Index location, Enterprise Vault needs to be quiesced before the backup job starts. The way quiescence is achieved in Enterprise Vault 7.5 is different from how it is achieved in Enterprise Vault 8.0 and later.
Note:
Enterprise Vault uses three terms to define quiescence. Those three terms are read-only mode, backup mode, and quiescence. These terms are used interchangeably in reference to Enterprise Vault.
For Enterprise Vault 7.5, the following applies when NetBackup quiesces Enterprise Vault:
Quiescence always happens at the Enterprise Vault server level. For example, if only one vault store needs to be backed up, the entire Enterprise Vault server is put into read-only mode.
When an Enterprise Vault server is put into read-only mode, you can access the data, however you cannot archive any data. Even if only one open partition is backed up the archiving cannot not happen in any of the vault stores in the Enterprise Vault server.

In Enterprise Vault 8.0 or later a more granular method to quiesce Enterprise Vault components is used.
