Image backup performs a block-level backup, typically to tape. Free space is not backed up. Image backup is used only to provide a base backup for remote seeding and to protect the Catalogic DPX Open Storage Server. For remote seeding, Image runs only as a base backup; for protection of Catalogic DPX Open Storage Server, Image runs as an initial base backup followed by incremental backups. Image backup is not supported for incremental or differential backup of clients. However, if incremental or differential Image backup information exists in the Catalog from an upgraded environment and the Image backups are preserved, the backups can be used for restores. For Linux Users, note that only base backup is supported for remote seeding purposes.
Only appropriate device clusters or tape libraries appear in the destination pane of the backup window. DPX directs the data to one of those storage devices.
The minimum amount of free disk space required on the client to run Image backup jobs is as follows:
10% of the total volume size for volumes smaller than 5 GB and 500 MB for volumes greater than or equal to 5 GB.
For Image backups, if the status of a disk object is offline, you cannot browse the disk in the management console or select it for backup.
File exclusion is not supported for Image backup.
Selecting a descendant resource for exclusion by clicking it is not permitted in the source pane of the Image backup window.
Only one snapshot of a volume can exist at any time on a volume. Thus if you run an Image backup of a volume that is currently being backed up by a different Image backup job or a Block backup job, it will fail.
Mount points appear to the right of the volume icon in the format:
{volume_name} mount_point_directory
Image backup does not directly support the backup of active database applications. Run a Block backup after seeding to recover application-consistent data.
Image backup is not supported for clusters.
Before running an image backup, you need to create an Image Backup Job.
Restrictions. In Catalogic DPX version 4.10, only the desktop interface supports Image backups.
In the main desktop interface window, go to the Backup tab, and from the Backup Modes section in the task panel, choose Image.
Two additional panes will appear. You are already in the defining new image backup job, so there is no need to click the Define New Backup Job button under Job Tasks.
Specify the Image backup source in the middle pane. You can drill down only as deep as to the volume level.
Specify the Image backup destination in the right-hand side pane. Expand the tree as necessary.
Note. Before running a backup job, you need to save it. Once saved, a previously defined job can be modified, run, or deleted. If you try to leave the job creation view without saving the changes, you will be prompted to either save or discard changes before leaving.
If you select Define New Backup Job, all unsaved changes will be lost.
To add a schedule to an Image backup job, start creating a new job or open a saved job to edit it.
Go to the Backup tab and from the Backup Modes section in the task panel, choose Image.
Under the Job Tasks section, select Schedule Backup Job. The Job Schedule dialog will open.
This dialog box contains three tabs along the top: Schedule, Exceptions, and Preview.
The Schedule tab allows you to define the dates and times you want the current job to run.
The Exceptions tab allows you to list any exceptions to that schedule.
The Preview tab allows you to view all jobs scheduled for a specified future date.
Note. For File, Image, and NDMP backup jobs only, you can use the scheduler to define a Migrate operation. See Specifying an Automatic Migrate Operation in the DPX 4.9.x Reference Guide.
Select the Schedule tab. Using the Schedule window, you systematically define the schedule for the particular job you are defining. A single schedule definition for a single job can include many schedule description items or job schedule elements, which can be for different frequencies and different backup types. The following illustrates a schedule definition that contains three job schedule elements. Note that after defining the schedule, you will have an opportunity to exclude particular events by using the Exceptions tab.
Add job schedule elements one by one. To do so:
Click New.
In the New Schedule box, select a frequency. The following list describes your choices:
| Freq | Description |
|---|---|
Fill in the relevant details. The following table provides an overview of the field definitions. The field definitions may vary depending on the frequency you selected.
| Freq | Field | Definition |
|---|---|---|
Click Apply. The job schedule element is added to the “Schedule Description” list at the top of the window.
Repeat steps 4.1 through 4.4 as needed to define the schedule for the particular job you are defining.
Select the Exceptions tab if exclusions are desired. This window allows you to exclude any future scheduled runs of the job. Add exclusion description items one by one. To do so:
Click New.
In the New Exclusion box, select from the display calendar the date of your desired exclusion. In the display calendar, the dates for which the current job is scheduled are denoted in purple. The job elements scheduled for that date appear in the box.
To exclude certain job elements scheduled for that date, click Select one or more entries to exclude, then select the desired jobs from the entries listed in the box. To exclude all job elements scheduled for your selected date, click Exclude whole day.
Click Apply. The exclusion description item is added to the Schedule Description list at the top of the window.
Repeat steps 6.1 through 6.4 as needed to define the exceptions for the particular job you are defining.
You can also indicate whether or not scheduled jobs should be skipped on holidays by clicking to select or unselect Skip Run if Holiday.
Click OK. The schedule and exceptions you just defined are associated with the job you are defining.
Tip. Remember to save the job definition after you specify a job schedule.
Editing an Image backup job allows you to change some parameters of an already defined job (Save), or to create a new job based on the definition of an existing one (Save as…). The procedure is similar to creating a backup job from scratch.
In the main desktop interface window, go to the Backup tab, and from the Backup Modes section in the task panel, choose Image.
Under Job Tasks in the side panel, select Open Backup Job. The Open Job dialog will appear.
Note. The Job List includes all Image job names, regardless of the folders they are stored in. The Folder field indicates the actual folder where the selected job is stored.
Select the job you want to edit from the list. Click OK. The Open Job dialog will close and the settings of the selected job will be loaded to the main window view.
When finished, save the job by doing one of the following:
Select File > Save Job
Select Save Backup Job in the Job Tasks section of the side panel
Press [Ctrl + S]
The Save Job dialog will appear.
Restrictions. The new job name must be unique throughout the entire DPX, regardless of the folder the job is stored in.
Click OK. If you choose the same name, you will be prompted to confirm the replacement of the already existing job. Select Yes to change the job definition, or No to return to the previous step and specify another name for the job.
Proceed with editing the job. See for more details.
