This setting determines whether or not to copy backups written to a virtual tape cartridge. If
set to Copy to device then backups written to the virtual tape cartridge are copied to a destination device.
If set to Do Not Copy, then backups written to the virtual tape cartridge are never copied to the copy
device. You can optimize the use of the copy device and its media by selectively copying backups to it.
For example, you may decide to copy only weekly or monthly full backups to the copy device, and leave
daily incremental backups on the virtual library. This policy would reduce the number of media required
for the copy device.
If you select the Do Not Copy policy, then the only version of the backup data is on the virtual
library. If the disks on which the storage folder resides crash, then data may be permanently lost.
virtual library. Use the Browse command to locate a device that is available in the Data Protector Express
management domain. HP recommends that you select specific devices instead of selecting any device on
the network. You can also select or exclude different types of devices instead of selecting specific
devices. You can select or exclude all tape devices, all virtual libraries, or all CD/DVD devices. This
setting is applicable only if the copy policy is set to Copy to device.
This setting determines how soon following the completion of a backup job to perform the copy
operation. This timeout (or delay) is only applicable if the copy policy is set to Copy to device. Enter or
scroll to the number of minutes following a backup to start the copy operation.
This setting determines how long data is retained on the virtual library. There are three
options for the retention policy.
•
overwritten or erased by a backup or media job. This is a good policy to use for backups that you
want to stay "online" for fast restores from a virtual library at any time.
•
copied to the copy device. In this case, space in the storage folder will be freed up after the copy
operation completes. This is a good policy to use if you want to fully optimize the use of space in the
storage folder.
•
successfully copied to the copy device, and the storage folder is not full. If during a subsequent
backup the storage folder becomes full, the backup data will be automatically deleted from the
storage folder to make room for the new backup. Only backups that have been successfully copied to
the copy device will be removed under this policy. This policy is the best one to use for normal
operations. It will provide the best balance of retaining backups in the virtual library and optimization
of storage folder space. Data will be removed from the storage folder following least-recently-used
(LRU) order.
Use this command to set up the log options for each copy job. Identical to the Log
options command on the Options property page of any job, you can set up a log that Data Protector
Express will save, print or email to a designated user each time a copy job is run. For more information
about job logs, refer to Log options on page 108.
When a backup is copied under the D2D2Any option, every object (file, folder, etc.) in the original
backup is copied to the copy device, and each version is recorded in the Data Protector Express catalog.
Upon normal restores, Data Protector Express will automatically select the most current version of an
object to restore, regardless of the media on which it resides. Data Protector Express makes this selection
based on the time and date that the object was backed up, and the most efficient device/media to get it
from.
This setting determines the destination device for backups that are stored on this
