How To



Exchange properties on Windows

The Exchange properties apply to the currently selected Windows clients. For clustered or replicated environments, configure the same settings for all nodes. If you change the attributes for the virtual server name, only the active node is updated.


Except for Exchange granular restore proxy host, these host properties do not apply to VMware backups that protect Exchange.

Exchange dialog box

The Exchange dialog box contains the following properties.

Table: Exchange dialog box properties



Snapshot verification I/O throttle

For snapshot backups, specify the number of I/Os to process for each 1-second pause. This option applies to Exchange 2003 SP2 and to Exchange 2007 if the Exchange Management Console is not installed on the alternate client.

See About configuring a pause in consistency checks for Exchange 2007 and earlier.

Backup option for log files during full backups

Choose which logs to include with snapshot backups:

  • Back up only uncommitted log files

    Select this option to back up only the log files that are uncommitted. This option is not recommended for Exchange 2010 DAG or Exchange 2007 CCR environments.

  • Back up all log files (including committed log files)

See About backing up all or only uncommitted Exchange transaction log files with snapshot backups.


As of NetBackup 7.0, the default option is now Back up all log files (including committed log files). If you previously changed this setting for a client, your selection remains the same. For new installations of NetBackup, the default is Back up all log files (including committed log files). For upgrade installations where you did not change this setting for a client, the default is changed to Back up all log files (including committed log files)

Truncate log after successful Instant Recovery backup

Enable this option to delete transaction logs after a successful Instant Recovery backup. By default, transaction logs are not deleted for a full Instant Recovery backup that is snapshot only.

See About truncating Exchange transaction logs with Instant Recovery backups.

Exchange granular restore proxy host

You can specify a different Windows system to act as a proxy for the source client. Use a proxy if you do not want to affect the source client or if it is not available. This situation applies when you duplicate a GRT-enabled backup image from a disk storage unit to a tape storage unit or when you use the bplist command.

For complete information on this option, see the NetBackup for Microsoft Exchange Server Administrator's Guide.

See Configuring the granular restore proxy host.

See About Exchange client and server privileges

Mailbox for message level backup and restore

As of NetBackup 7.0, this setting no longer needs to be configured.

Enable single instance backup for message attachments

Enable this option to back up the data that is stored on a Single Instance Store (SIS) volume. This feature only applies to Exchange Server 2007 and earlier versions.

See About configuring Exchange Single Instance Store backups (Exchange 2007 and earlier) .

Perform consistency check before backup with Microsoft Volume Shadow Copy Service (VSS)

Disable this option if you do not want to perform a consistency check during an Exchange 2010 DAG backup. If you check Continue with backup if consistency check fails, NetBackup continues to perform the backup even if the consistency check fails.

See About consistency checks options for an Exchange 2010 backup.
