5. Specify the following options:
• The name of the application system.
When backing up cluster-aware writers (such as SQL Server via the MSDE
Writer, or Exchange Server in the LCR or CCR environment), specify the
virtual server name given in the particular writer resource group as the
application system.
• For a transportable backup, the name of the backup system from where the
shadow copy can be backed up to tape or where you want your shadow
copies to be presented and mounted after the backup.
• For local or network backup, the type of provider: select Use hardware
provider if you want to enable instant recovery and specify other backup
options.
• To enable instant recovery, select Track the replica for instant recovery.
• If you have selected Track the replica for instant recovery, specify the
configuration check mode. Configuration check applies to the disk backups
that are to be used for instant recovery and does not apply to the tape
backup. For information on the options, see “Configuration
check” on page 353.
• If you do not select Track the replica for instant recovery, you can specify
the replica type:
Default
The replica type created depends on the VSS hardware provider
configuration.
Mirror/Clone (Plex)
A shadow copy, independent from its source volume is created:
• With EVA hardware provider, snapclone is created.
• With XP hardware provider, the replica created depends on the
provider mode (clone in the case of VSS compliant mode, or mirror
in the case of resync mode).
Snapshot (Differential)
A shadow copy, dependent on its source volume is created: by default,
standard snapshot is created (with pre-allocated disk space).
This replica type is not supported by XP hardware provider.
A provider may support one or both types. If you select an unsupported
replica type, the backup will fail.
For more information on EVA provider replica types, see “Snapshot
replica” on page 361.
• Optionally, specify other replica management and mount options.
