Configuring Logical Devices

To create a new logical device, click Create on the ribbon, and then select Logical Device from the drop-down menu. To modify a previously configured logical device, select the logical device, and then click Edit on the ribbon.

In the Create Logical Device or Edit Logical Device interface, configure the following settings:

2. Data Storage Type – Select the device type according to different types of the data you are about to store:

 Standard storage device – This storage device can be used to store all kinds of data. It is the common type of device.

 BLOB storage device – This storage device is used to store the BLOB data. It can only be used for the Storage Manager.

*Note: When selecting the BLOB storage device, you can select the Configure Folder Structure feature to generate the BLOB data folders in the structure you selected.

 Redundant backup data storage device – Stores the data of Platform Backup and Granular Backup.

*Note: When selecting the Redundant backup data storage device, add two storage groups so that if the current storage group is damaged, the data can be obtained from the other storage group.

 Concurrent storage device – Backs up data to the device with the optimal performance instead of the next one in the device order, which improves backup efficiency.

*Note: Once the Data Storage Type is configured, it cannot be modified later.

3. Storage Type – From Storage type drop-down box, select the storage type for this logical device.

This will determine the physical devices available to be added to this logical device. Note that when you have selected the Blob storage device, the Redundant backup data storage device and the Concurrent storage device as Data Storage Type, only the Net Share and IBM Storwize Family can be selected as Storage Type.

4. Add Physical Device – Select the physical device you wish to add from the Physical Device drop-down menu. You can also choose New Physical Device to create a new one. Click Add to add the physical device to this logical device. For more information on creating a new physical device, see the Configuring Physical Devices section of this guide.

You can change the order of the physical devices by selecting a different position number in the Order drop-down box. The data/index will be stored in the physical device according to this order. For each physical device that you add, you may select Data, Index, or both by selecting the corresponding checkbox that you want to store in this physical device. By default, both options are selected. To remove a Physical Device, click the corresponding remove (X) button.

Note: On the Edit Logical Device interface, if you have more than one physical device added to this logical device, and if you deselect the Data/Index checkbox or remove a physical device, a confirmation window will pop up when you click Save. The pop up will inform you that the old backup data will be unavailable until you copy the old data and/or index manually to a new physical device. You must create new folders under the path of the new physical device, with the same name and the same hierarchy as the old physical device, and copy the old data and/or

index manually into their corresponding folders. Otherwise, the old data/index cannot be found after data recovery.

When the BLOB storage device or the Redundant backup data storage device is selected in the Storage Type section, click the Add a Storage Group link in the Add Physical Device section to add a storage group. To add a storage group, complete the following steps:

 Add a Storage Group – This feature is used for the BLOB storage device and the Redundant backup data storage device. When selecting Standard storage device and Concurrent storage device, the Add a Storage Group link will be hidden.

 Please choose the synchronization method for the specified storage groups – This feature is only used for the BLOB storage device. When more than one storage groups have been added, this feature will be displayed. This feature allows you to enable data synchronization among several storage groups and provide high available performance to your data. This means that if the current used storage group is damaged, the data can be obtained from the other storage groups. This option is only available for Net Share and IBM Storwize Family physical devices and it is only supported for Real-Time Storage Manager and Scheduled Storage Manager. This feature will help you synchronize data to all of the storage groups. The storage groups will be used in the order that they have been added. The primary group will be used first by priority.

o Asynchronous – Enables the data to be written into the first available storage group, and then DocAve will copy the successful written data from the specified storage group to all of the other storage groups.

o Synchronous – Enables the data to be written into all storage groups at the same time. The synchronization thread will keep all of the data in the storage groups same, complete and correct.

5. Configure Folder Structure – This is an optional feature. When selecting the BLOB storage device, configure the Configure Folder Structure field to generate the BLOB data folders in the structure you selected here. After selecting the Create storage path for contents using the following structure checkbox, select the following radio buttons:

 Time and date – Adds additional information such as modified time to the path to make the identification of BLOBs in the storage location easier. Select one of the following four options from the drop-down list:

o YYYY/MM – Select this to generate the folders. The directory of your stored data is .../YYYY/MM.

o YYYY/MM/DD – Select this to generate the folders. The directory of your stored data is .../YYYY/MM/DD.

o YYYY/MM/DD/HH– Select this to generate the folders. The directory of your stored data is .../YYYY/MM/DD/HH .

o YYYY/MM/DD/HH/mm – Select this to generate the folders. The directory of your stored data is .../YYYY/MM/DD/HH/mm.
