Configuring Backup Quotas for Exchange Mailboxes
Setup Exchange Mailbox Backup Quota to check for mailboxes in a subclient that exceed the quota that is set for the subclient. Mailboxes that exceed 90 percent of the quota generate a warning email. Mailboxes that exceed the quota generate an alert email and are not backed up until some backed up messages are deleted from secondary storage.
The first backup operation for a new subclient cannot enforce limits because the subclient must be backed up once to determine how much backup storage space a mailbox is actually consuming. That amount is usually less than the source data because of factors such as deduplication and compression.
Tip: If it seems that quotas are not enforced, run the backup job for that subclient a second time. After the backup job completes, confirm that the mailboxes that are over the specified quota generate notifications as expected.
If you enabled source pruning for end-user delete, then deleting backed up messages from secondary storage also removes them from primary storage (that is, the Exchange server).
Before You Begin
- You must enable Exchange Mailbox Backup Quota.
- Install and configure the Web Server.
- Install Exchange package and add the agent on the client where the quotas need to be configured.
- Make sure that the agent has completed a least one backup job.
- Install and set up the Private Metrics Reporting Server to view the reports. For more information, see Getting Started with Metrics Reports.
- From the CommCell Console, expand Client Computers > client > agent > backup_set.
- Right-click a subclient, and then click Properties.
The Properties dialog box appears.
- On the General tab, select the Mailbox Quotas (based on media usage) check box.
- In the Skip mailboxes that have exceeded n MB box, type a new media usage limit.
- Click OK.
The limit is enforced the next time the subclient is backed up. If a mailbox exceeds 100 percent of its quota, the mailbox is not backed up again.
What to Do Next
If mailboxes that approach or exceed their quota prevent messages from being backed up, you can do the following:
- Increase the quota for the subclient.
- Enable End-User Delete so that users can remove backed up messages by browsing and deleting them. For more information, see Exchange Mailbox End-User Delete.
