Description

Seeding is the process in which a copy of a mailbox database is added to another Mailbox server. This becomes the database copy into which copied log files and data are replayed.

The Update-MailboxDatabaseCopy cmdlet can also be used to seed a content index catalog for a mailbox database copy. When you do this, the MAPI network is used, regardless of the value you specify with the Network parameter.

You must suspend a database copy before you can update it using the Update-MailboxDatabaseCopy cmdlet. For detailed steps about how to suspend a database copy, see Suspend or resume a mailbox database copy.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Update-MailboxDatabaseCopy -Identity DB1\MBX1

This example seeds a copy of the database DB1 on the Mailbox server MBX1.

Example 2

Update-MailboxDatabaseCopy -Identity DB1\MBX1 -SourceServer MBX2

This example seeds a copy of the database DB1 on the Mailbox server MBX1 using MBX2 as the source Mailbox server for the seed.

Example 3

Update-MailboxDatabaseCopy -Identity DB1\MBX1 -DatabaseOnly

This example seeds a copy of the database DB1 on the Mailbox server MBX1 without seeding the content index catalog.

Example 4

Update-MailboxDatabaseCopy -Identity DB1\MBX1 -CatalogOnly

This example seeds the content index catalog for the copy of the database DB1 on the Mailbox server MBX1 without seeding the database file. The content index catalog seeding occurs over the MAPI network.

Example 5

Update-MailboxDatabaseCopy -Server MBX1

This example performs a full server reseed of all of the databases on the Mailbox server MBX1.

Parameters

-BeginSeed

The BeginSeed switch asynchronously starts the seeding operation and then exits the cmdlet. You don't need to specify a value with this switch.

This switch is useful for scripting reseeds.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-CancelSeed

The CancelSeed switch specifies whether to cancel an in-progress seeding operation. You don't need to specify a value with this switch.

Type:SwitchParameter
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-CatalogOnly

The CatalogOnly switch specifies that only the content index catalog for the database copy should be seeded. You don't need to specify a value with this switch.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

The DeleteExistingFiles switch specifies whether to remove the existing log files at the target location. You don't need to specify a value with this switch.

This switch removes only the files that it checks for and fails if other files are present. No action is taken on other files at the target location. Therefore, if database-related files are present, you must manually remove them.

Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Force

The Force switch hides warning or confirmation messages. You don't need to specify a value with this switch.

You can use this switch to run tasks programmatically where prompting for administrative input is inappropriate.

Type:SwitchParameter

Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

With this switch, you can manually resume replication to the database copy.

-SafeDeleteExistingFiles

The SafeDeleteExistingFiles switch specifies a seeding operation with a single copy redundancy pre-check prior to the seed. You don't need to specify a value with this switch.

Because this switch includes the redundancy safety check, it requires a lower level of permissions than the DeleteExistingFiles parameter. Limited permission administrators can perform the seeding operation by using this switch.
