Changing The Tape Set Count; Managing Backups With Or Without Media Rotation - HP BB118BV - StorageWorks Data Protector Express Package User Manual

You can change either the length of the full data recovery period or the level of access to historical copies
for media rotation plans. By modifying the tape set count, you can lengthen or shorten the period in which
full data recovery is available or the period of time for which historical files are available.
For example, you may wish to increase the number of yearly historical tapes available from two to three
or more. To do so, change the number in the Sets box for Yearly set types on the Schedule property page
to the desired number of historical backups.
Alternatively, you may wish to expand the full data recovery period, while limiting the number of
historical backups. As you change the number of media groups you want to maintain, Data Protector
Express updates the number of sets required for the backup job.
To view when a group will be used during the life of the backup job, select Sample.

Managing Backups with or Without Media Rotation

If you create a backup job that does not include media rotation, you must manage your backup media sets
manually. That is, you are responsible for ensuring that the expected media is in a backup device before a
job runs. Data Protector Express will not prompt you to insert the correct media in a backup device
because there is no media rotation plan to follow.
The schedule types Run now, Run on specific day, Run on selected days, and Not scheduled all
require you to manage your own backup media sets. To make data recovery easier, Data Protector
Express sets the backup mode to Full for any job created with these schedules. Running a job in Full
backup mode ensures that you can use the media set to recover data easily. To change the backup mode
for these jobs, edit the Backup Mode setting on the Options property page.
For all other schedules, you must choose whether or not to include media rotation. You can also alter the
backup mode if the default settings do not suit your data recovery needs. By default, Data Protector
Express sets the Rotation Type to No rotation.
Follow the guidelines below to determine how best to manage your media and how to set the backup
mode.
