Enterprise Vault™ Administrator's Guide

Configuring partition rollover

In each vault store where you use partition rollover, the open partition must be rollover enabled, and there must be at least one ready partition. For partition rollover to work for an extended period without intervention, each ready partition in a vault store must also be partition rollover enabled. If not, partition rollover stops at the first partition that is not rollover enabled. In summary, for Enterprise Vault to roll over through a series of partitions, each must be both ready for partition rollover, and partition rollover enabled.

You can enable and configure partition rollover for each partition when you create it using the New Partition wizard. For more information on creating a new vault store partition, see the Setting up storage chapter of the Installing and Configuring guide. You can also configure partition rollover for existing vault store partitions, using the Vault Store Partition Properties page.

This flexibility enables a number of approaches to the management of partition rollover. You can take a purely volume-based approach, in which you configure a series of partitions that roll over when their host disks approach capacity. Normally, this approach would require you to create the partitions on separate physical disks. However, it is still possible to host partitions on a single disk when you mount multiple physical volumes in one file system. In this case, Enterprise Vault rolls over based on the free space on the physical volume, rather than on the host file system.

The time-based approach to partition rollover lets you roll over according to any time criteria that suit your environment. For example, you can configure partitions to roll over at the end of each week, or on a specific date each month.

Enterprise Vault also lets you use a mixture of volume and time criteria.
