Data Protector Express User's Guide and Technical Reference
•
How much data can the backup media hold? How many media does my budget allow me? Or,
alternatively, how many tapes does my library hold?
As you review the following sections, keep these questions in mind to help you determine which backup
job schedule to select for any particular job.
Non-scheduled backup jobs
Some jobs may run once or only occasionally. Historical files provide a record of the data stored on the
computer or network at particular times such as the end of the week or the end of the month. For jobs that
do not need to run automatically on a regular schedule, Data Protector Express provides four options:
Not
scheduled
,
Run now
,
Run on specific day
, and
Run on selected days
. By default, backup jobs are not
scheduled. You must start these jobs manually each time you want to run them. To use a different
schedule type, you must select it from the
Schedule Type
list on the
Schedule
property page for the job.
A backup job that uses the
Run now
schedule type, will begin as soon as you finish setting it up.
NOTE:
No jobs will start until the database server has been running for a minimum of five minutes. This
allows the user a chance to shut down jobs that should not run immediately after the server is restarted.
NOTE:
If you plan to set up media rotation, choose
Run repeatedly
. If you intend to manage your media
manually, select any type other than
Run repeatedly
.
TIP:
Backup jobs designed to protect data from disaster should always be scheduled. This is the most
effective way of insuring that your data will be safely stored on media with regular backups. Media
rotation also helps protect your data by insuring that media is not over-used.
Scheduled backup jobs
Backup jobs designed for disaster protection are run routinely, usually daily. Data Protector Express
contains the Run repeatedly schedule type that is designed to provide different levels of data availability
for recovery in the event of data loss or a hard disk failure. This schedule type allows backup jobs to be
run at different intervals:
Minute
,
Hour
,
Day
,
Week
,
Month
, or
Year
.
For more information on how these scheduling options affect media rotation see
Chapter 7 – Planning for
Media Rotation
.
Customizing Schedules
CAUTION:
It is strongly recommended that you use the default schedules for disaster recovery. These
schedules are specially designed to secure your data against catastrophic loss over time. If you need a
