Chapter 9: Running Jobs 127
For example, suppose that a backup job is scheduled to run as an incremental job in the evening. If it is
forced to run before its scheduled time, Data Protector Express will not update the
Backup Mode setting.
In this case, if the last time the job was run, it was as a full backup job, the Backup Mode setting on the
job’s Option page will still be set to Full . As a result, when you force the job to run, it will be run as a
full backup job, even though it is next scheduled to run as an incremental job.
Forcing a job to run can be useful when a job failed to run for some reason. For example, suppose a full
backup job is scheduled for a Saturday, but a network equipment malfunction prevented the job from
being run as scheduled. It is important that another
full backup job be run before the next incremental job.
This is the only way to ensure that the full data recovery period is not compromised. On Monday, you can
force the failed backup job to run again after the network connections are restored. Before you run the
job, open the job’s property page and make sure the proper job type and media are selected.
Before forcing a scheduled job to run, you should always check the Options page of the job to see that
the option settings are set correctly. If you are forcing the job to run because an earlier job failed to run
properly, you can look at the log of the failed job to see which settings the job would have used.
How forcing jobs to run affects permissions
When a job is run, Data Protector Express will check for the appropriate permissions to the device, files,
media, and so on. Data Protector Express calculates these permissions by using the permissions of the
user who scheduled the job. The
Scheduled by
field lists the user who scheduled the job. The
Run by
field lists the user who forced the job to be run. After a job is run, the job owner is reset to the last user
who changed the job properties; forcing a job to run does not permanently change the job owner.
When the Data Protector Express administrator creates and schedules a job, the owner of the job is the
administrator. Data Protector Express will use the Data Protector Express administrator’s permissions
when running the job. Similarly, if another user creates and schedules a job, that user will be the job’s
owner and Data Protector Express will calculate the job’s permissions using that user’s permissions.
However, if a scheduled job is forced to run, the person who forces the job to run becomes the job’s new
owner. So, for example, if the Data Protector Express administrator forces a job to run that another user
has created, the Data Protector Express administrator becomes the job’s new temporary owner and Data
Protector Express calculates the permissions using the Data Protector Express administrator’s
permissions.
Changing the job’s owner can be useful for managing security. A user can create and schedule a job, even
though that user lacks the proper permissions to run that job. Another user, such as the Data Protector
Express administrator, can then force that job to run with their own permissions.
Viewing and printing scheduled job instructions
Whenever a job is scheduled and placed on the Job Status view, Data Protector Express creates a set of
instructions for that job. Included in a job’s instructions is information about which media set must be
available to be used and which backup devices it may be inserted into. For example, when running an
automatic rotation job, the instructions for that job include the name of the media Data Protector Express
is expecting to use when that job runs next, such as “Daily Set 1” or “Yearly Set 2”. The instructions also
include the name of the backup devices which Data Protector Express expects to be available when the
job runs.
TIP: You can use the instructions to ensure that all of your jobs run correctly by planning ahead to see that
each job has the media it requires before it runs. For example, you can print the instructions and then
assign a co-worker the task of inserting the proper media into various backup devices by the required
time.
