Backing Up Changed Files Only; Working With Mapped Drives - HP BB118BV - StorageWorks Data Protector Express Package User's Manual & Technical Reference

Allow Parents
for the parent along with the file. This option must be checked in order for folders and other directory
data to be backed up. When this option is not checked, Data Protector Express will not back up any
parent information for any file backed up.
Allow Children
folders. If you want to back up only the marked directories, however, you can clear this option. When the
Allow Children box is unchecked and the Allow Parents box is checked, Data Protector Express backs up
the directory structure, but not the files stored in the directories (that is, in the folders).
This option can be useful for replicating a complex directory structure. Begin by marking the directory
structure you wish to duplicate. Then clear the Allow Children option. Data Protector Express will back up
only the directory structure. You can then replicate that directory structure to any volume by restoring
the directory to that volume.
Media Data Protector Express tracks versions of files and the media on which those versions are stored.
You can use this information to sort files according to the media on which they appear. Only files with
versions on the media in the Media field will be selected for the backup job.
For example, if you select media named "Daily Set:1," Data Protector Express will only include files in the
backup job which have a valid version on the media named "Daily Set:1."
To sort files according to the media on which they appear, click the Add button and select the media
from the Browse window.
NOTE:
You must select a Media object, not a Media folder or User/Group folder. If there are multiple media
shown in the Media filter field, only files which have a valid version on
This filter has limited applications for backup jobs. One way to use it, however, would be in the case
of media you know is corrupt or damaged. To back up a new version of every file on that damaged
media, begin by creating a new job and then selecting the appropriate Network or Machine object on
the Selection page. Then open the Selection Filters window by clicking on the Selection Filters button.
Add the damaged media to the Media field. Then set the Backup mode on the job's Options page to
Copy . When Data Protector Express runs the job, it will only back up files which had a version on
the damaged media shown in the Media field.
Backing up changed files only
When you run a job repeatedly, particularly backup jobs designed for disaster protection, many times
you only want to back up files that have changed since the last time you ran a backup job. Data Protector
Express handles this with the backup mode setting. The backup mode is specified on the Options page
for the job.
If you want to back up all selected files, use the Full backup mode setting..
If you only want to back up only files that have changed since the last full backup, use the Differential
backup mode setting. Files that have not changed since the last full backup will not be backed up.
If you only want to back up files that have changed since the last backup, use the Incremental backup
mode setting. Files that have not changed since the last backup, regardless of its mode, will not be
backed up.

Working with mapped drives

Data Protector Express can be configured to include or exclude mapped drives during file selection. Once
configured, these drives will appear on the Selection page of a job.
