C:\Users\Administrator>I can see from the above output that the last backup was performed on December 15, 2015 at 10:32 AM to an external USB drive that the system designates as drive E. The only prior backups using the built-in Microsoft Windows backup program were made to DVDs in March of 2012.
If you want details on what was included in a backup you can use
the GET ITEMS parameter for the command.
C:\Users\Administrator>wbadmin get items

ERROR - An option required for the command is missing: Version. See the
syntax below.
Syntax: WBADMIN GET ITEMS
-version:<VersionIdentifier>
[-backupTarget:{<BackupDestinationVolume> | <NetworkSharePath>}]
[-machine:<BackupMachineName>]
Description: Lists the items included in a specific backup.
To use this command, you must be a member of the Backup Operators group
or Administrators group.
Parameters:
-version Specifies the version of the backup in MM/DD/YYYY-HH:MM format.
If you do not know the version information, type WBADMIN GET
VERSIONS.
-backupTarget Specifies the storage location that contains the backups for
which you want the details. The storage location can be a
locally attached disk drive or a remote shared folder. If
WBADMIN GET VERSIONS is run on the same server where the
backup was created, this parameter is not needed. However,
this parameter is required to get information about a backup
created from another server.
-machine Specifies the name of the computer that you want the backup
details for. Useful when multiple computers have been backed
up to the same location. Should be used when -backupTarget is
specified.
Examples:
WBADMIN GET ITEMS -version:03/31/2005-09:00
WBADMIN GET ITEMS -version:04/30/2005-09:00 -backupTarget:\\servername\share
-machine:server01
C:\Users\Administrator>E.g., if I wanted details for the first backup, which had a backup time of 3/11/2012 4:07 AM, I could use the command below:
C:\Users\Administrator>wbadmin get items -version:03/11/2012-09:07

C:\Users\Administrator>Note: you need to use date and time information from the "Version identifer"
line, not the "Backup time" line, that you see when you run the
wbadmin get versions command. Also you need to use the information
exactly as formatted on that line. In the case above I needed to provide the
date and time information as MM/DD/YYYY-HH:MM where MM
represents month, DD the day, YYYY the year, HH
the hour and MM the minute. Using "3" for the momth,
instead of "03", or "9" for the hour, instead of "09" would result in the
command displaying help information for the command rather than details on that
backup. The hours are represented in
24-hour clock,
aka "military time", format, so "21:00" is 9:00 PM. The date format may vary depending on
the country for the system, so may be different on your system.
