Data Range - HP BB118BV - StorageWorks Data Protector Express Package User's Manual & Technical Reference

Backup Range When a file is backed up, Data Protector Express stores the backup date in the catalog.
This is called the backup date. Each time you back up a file, Data Protector Express changes the backup
date to match this newer backup date. You can view information for all available backup versions file in
the Versions of window. You can use this information to filter files for verify jobs. You can use this filter
for files that have been backed up on specific dates. More often, however, you would use this filter to
filter out files that have been recently backed up.
To select files that have specific backup dates, click on the Browse button next to the Backup range
field. In the Date Range window that appears, select the appropriate range type and the starting and
ending dates and times.

Modify Range Each time a file is modified, its modified date is updated. You can use this filter to
back up files whose modified date matches your criteria. Data Protector Express checks the directory
information on the volume to see if the file should be included for backup.
For example, you can select only those files that were modified after a certain date and time or, alternatively,
those that were modified before a certain date and time.
To select files that have specific modify dates, click on the Browse button next to the Modify range
field. In the Date Range window that appears, select the appropriate range type and the starting and
ending dates and times.
Create Range When a file is first created, it is assigned a create date. You can use this filter to select
only those files that match your criteria. Data Protector Express checks the created date for each file stored
in the directory of the volume and uses this to select files for backing up.
To select files that have specific creation dates, click on the Browse button next to the Create range
field. In the Date Range window that appears, select the appropriate range type and the starting and
ending dates and times.
Access Range Each time a file is read, whether or not it is modified, its access date is updated. You
can use this information to select files for backup.
For example, you might want to back up only those files which have been accessed (opened or read) in
the past two months. Alternatively, you could back up only those files which have not been accessed in the
past two months.
To select files that have specific access dates, click on the Browse button next to the Access range field. In
the Date Range window that appears, select the appropriate range type and the starting and ending
dates and times.
Size Range This filter lets you select files for backup according to their sizes. You might want to select
only smaller files, larger files or files between two sizes.
