Copies
|
The number of copies to create concurrently. You can create up
to four or the number of copies specified in the Maximum Backup
Copies field for the NetBackup master server (if less than four).
(Configured in NetBackup Management > Host Properties >
Master Server > server_name > Global NetBackup Attributes.)
By default, the value is two: one original backup and one copy.

For Each Image, If This Copy Fails
|
The action to perform if a copy fails: Continue or Fail All
Copies.
In Vault, if you choose Fail All Copies, all copies of that
image fail, independent of the success or failure of other image
copy operations.
The next time the Vault profile runs, Vault again
tries to duplicate the image if the following conditions are
true:
By default, the option is configured to Fail All Copies in
Vault.
If you choose Continue for all copies, Vault considers the
duplication job successful if any of the copies succeed. However,
it is possible that a copy of the image may never get vaulted. It
is probable that at least one copy will succeed, but it may not be
the copy assigned to the off-site volume pool.
|
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.
|
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 configured
continue as the fail option, the first successful copy is the
primary copy.
|
Retention
|
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 catalogs,
the volume is recalled from off-site storage, and the backup image
is unavailable for a restore.
|
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 off-site volume pool to which Vault assigns the
duplicate media. Images on media in the off-site volume pool is
ejected for transfer off-site. 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.
