Alternate Read Server
|
This option applies to NetBackup Enterprise Server only.
The name of an alternate read server. If robots (or drives) are
shared by more than one media server, you can designate a different
media server to read the original backups than the media server
that wrote the backups. Using an alternate read server may transfer
data over your network, affecting your site's computing
environment. The Source Media Server and Alternate Read Server may
be the same.
By default this option is disabled. To configure an alternate
read server, select Alternate Read Server. Then select a media
server from the drop-down menu. For advanced duplication, click New
to configure duplication rules.
|
Change
|
For advanced configuration only, the button used to display the
Duplication Rule dialog box so you can change a destination media
server and duplication rules for that server.
If you select Alternate Read Server on the Duplication tab, the
Duplication Rule dialog box has fields for both Source Media Server
and Alternate Read Server. If you did not select Alternate Read
Server, only a Source Backup Server field appears.
|
Configure
|
For basic duplication only, the button used to display the
Multiple copies dialog box.
|
Delete
|
For advanced configuration only, the button used to delete the
selected destination media server and duplication rules for that
server.
|
Duplicate Smaller Images First (applies only to disk backup
images)
|
Select to duplicate images in smallest to largest order. This
capability applies only when duplicating disk backup images.
By default, Vault duplicates images from largest to smallest,
which improves tape drive utilization during duplication and
duplicates more data sooner. If you know that your most important
data is in smaller backup images, you can select this option so
that those images are duplicated before the larger images.
This choice does not affect the total time required to duplicate
the images.
Note:
|
By default, Vault duplicates tape images
using the time the backup was created. It duplicates images from
the oldest to the newest.
|
|
Duplication Job Priority
|
The priority to assign to the Vault duplication jobs, from 0 to
99999. A larger number is higher priority. All duplication jobs for
the profile run at the same priority.
Vault duplication jobs compete with other process in NetBackup
(such as regularly scheduled backups) for resources, including tape
drives. If you want your Vault duplication jobs to obtain resources
before other processes, assign a higher priority to the Vault jobs
than to other NetBackup processes. Priority for backups, restores,
and synthetic backups is assigned in the master server Global
Properties.
|
Expire Original Disk Backup Images
|
The delay (in hours) until duplicated backup images become
eligible to expire after the Vault session runs (applies only if
the backup images are on disk and the duplication job has selected
that copy as a source copy for duplication).
You can use this option to set an earlier time for the images to
become eligible to expire, however, the imageDB cleanup process
performs the expiration of eligible images as a separate operation.
The imageDB cleanup process is run every 12 hours by default. You
can change this default value using the Image DB Cleanup Interval
option on the node of
Master Server Host Properties on the NetBackup Administation
Console or the bpconfig -cleanup_int
command. Refer to the NetBackup Commands document for more
information about this command.
If the duplication of a disk image is not successful, the disk
image does not expire. In addition, if the number of hours (X)
equals zero, then the images expire immediately after a successful
Vault duplication occurs.
|
Expire Original Tape Backup Images
|
The delay (in hours) until duplicated backup images become
eligible to expire after the Vault session runs (applies only if
the backup images are on disk and the duplication job has selected
that copy as a source copy for duplication).
You may chose to set this option to expire original VTL images.
You can use this option to set an earlier time for the images to
become eligible to expire, however, the imageDB cleanup process
performs the expiration of eligible images as a separate operation.
The imageDB cleanup process is run every 12 hours by default. You
can change this default value using the Image DB Cleanup Interval
option on the node of
Master Server Host Properties on the NetBackup Administation
Console or the bpconfig -cleanup_int
command. Refer to the NetBackup Commands document for more
information about this command.
If the duplication of a tape backup image is not successful, the
tape image does not expire. In addition, if the number of hours (X)
equals zero, then the images expire immediately after a successful
Vault duplication occurs.
|
Make This Copy Primary
|
Whether the copy should be designated the primary backup. Only
designate a duplicate as the primary if the primary backup is
ejected and transferred off site.
NetBackup restores from the primary backup, and Vault duplicates
from the primary backup. By default, the original backup image
created during a NetBackup policy job is the primary copy. If the
copy that you indicate as primary fails, and you have configured
continue as the fail option, the first successful copy is the
primary copy.
|
Media Owner
|
The name of the owner of the media onto which you
are duplicating images. Specify the media owner from the drop-down
list box, as follows:
-
The media owner option Any lets NetBackup choose the media
owner. NetBackup chooses a media server or a server group (if one
is configured).
-
The media owner option None specifies that the media server that
writes the image to the media owns the media. No media server is
specified explicitly, but you want a media server to own the
media.
-
The media owner option Server Group allows only those servers in
the group to write to the media on which backup images for this
policy are written. All server groups that are configured in the
NetBackup environment appear in the drop-down list.
|
Multiple Copies
|
Whether to create multiple copies concurrently. You can select
Multiple Copies if the master server properties allow it.
If you select Multiple Copies, click Configure to display the
About the Multiple Copies options.
If you configure multiple copies, you cannot configure a Storage
Unit, Volume Pool, Retention Level, or Primary Copy on the basic
Duplication tab.
|
New
|
For advanced configuration only, the button used to display the
Duplication Rule dialog box in which you can add a destination
media server and duplication rules for that server.
If you select Alternate Read Server on the Duplication tab, the
Duplication Rule dialog box has fields for both Source Media Server
and Alternate Read Server. If you did not select Alternate Read
Server, only a Source Backup Server field appears.
|
Number of Read Drives
|
The number of drives to use for reading backup images. When you
enter a number of read drives, the same number is entered into the
Destination Write Drives field. You must have an equivalent number
of read and write drives available.
|
Preserve Multiplexing
|
Whether to preserve multiplexing. Multiplexing is the process of
sending concurrent, multiple backup images from one or more clients
to the same piece of media. This process speeds up duplication, but
slows down restores and disaster recovery processes. If the option
to preserve multiplexing is selected, the multiplexed duplication
process occurs for all multiplexed images that are selected for
duplication during a given Vault session.
If the source image is multiplexed and the Preserve Multiplexing
option is selected, ensure that the destination storage unit
configured for each copy has multiplexing enabled. Multiplexing is
configured in NetBackup Management > Storage Units.
Multiplexing does not apply to disk storage units or disk
staging storage units as destinations. However, if the source is a
multiplexed tape and the destination is a disk storage unit or disk
staging storage unit, selecting Preserve Multiplexing ensures that
the tape is read on one pass rather than multiple passes.
|
Retention Level
|
The retention level for the copy. Each copy has a separate
expiration date. If a retention level is not specified, the
expiration date is the same as the original. If you specify a
numeric retention level, the expiration date for the duplicate
media is calculated by adding the specified retention period to the
date the original backup was created. If you specify Use Mappings
for the retention level, the retention period is based on the
retention period of backup image copy 1.
When the retention period expires, information about the expired
backup is deleted from the NetBackup and Media Manager catalog, the
volume is recalled from off-site storage, and the backup image is
unavailable for a restore.
|
Skip the Duplication Step
|
Select if you do not want to configure duplication.
|
Source Backups Reside On
|
The location of the backup images: disk or removable media or
both. Vault duplicates images from the primary backup images on
removable media or from backup images on disk.
|
Storage Unit
|
The name of a storage unit that contains the resources to which
the copies of the backup images are written.
Storage units can be Media Manager storage units, disk storage
units, disk staging storage units, or Network Data Management
Protocol (NDMP) storage units.
If the Media Manager or NDMP storage unit has more than one
drive, the source and destination storage units can be the same.
NDMP storage units are supported only when one copy is created per
duplication rule. Because of potential NDMP performance
limitations, Symantec suggests that you duplicate between drives
that are directly attached to the same NDMP host.
If the duplicated backup images are to be vaulted, the media in
the destination storage unit must be in the Robotic Volume
Group.
All storage units must be connected to the same media
server.
|
Volume Pool
|
The name of the offsite volume pool to which Vault assigns the
duplicate media. Images on media in the offsite volume pool are
ejected for transfer offsite. Do not use the volume pool that was
used for the original backup. NetBackup does not verify in advance
that the media ID selected for the duplicate copy is different than
the media that contains the original backup. To ensure that two
processes do not try to use the same volume at the same time,
specify a different volume pool.
|
Write Drives
|
The number of write drives. This value is the same as the number
of read drives.
