Chapter 5: Selecting Files and Versions 87
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 verifying.
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 verifying. For example, you might want to verify only those files which
have been accessed (opened or read) in the past two months. Alternatively, you could verify 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 verifying according to their sizes. You might want to select only smaller
files, larger files or files between two sizes.
To specify a filter that sorts files according to their sizes, click on the
Browse
button next to the
Size
range field and then select the appropriate criteria in the Size Range window that appears.
Version Range
Each time Data Protector Express backs up a file, it creates a new
version
of that file. For example, a file
named Expense Account Reporting Form may have been backed up several times during the previous
months and years. Typically, each version of the file is stored on the backup media of a different job. Data
Protector Express tracks each version of a file separately in its catalog.
You can use this filter to instruct Data Protector Express to select files according to the number of
versions that exist in the catalog. You might, for example, instruct Data Protector Express to verify all of
the files for which there is only one version. When you set
Range type to At most and Maximum
versions to 1 , Data Protector Express only verifies those files with a single version.
Note, however, that having multiple versions of a file does not ensure that the versions you have reflect
the latest changes to the file. It may have been modified after the last time you backed it up. So your latest
version may not match the file’s current form.
