Specifying Files by Date (DATE) The DATE option specifies which files are stored based on two possibilities: * Store files that have been modified since a specified date * Store files that have not been accessed since a specified date Storing Files Modified Since a Certain Date Use the DATE parameter to store only files modified since a certain date. This enables you to do, among other things, a partial system backup. For example, suppose a full system backup was performed on September 30, 1993. The following STORE command would copy all system and user files modified since that date: :FILE T;DEV=TAPE :STORE @.@.@;*T;DATE>=09/30/93 The date must be entered in either the above format (mm/dd/yy) or as mm/dd/yyyy (for example, 09/30/1993). The files stored include any modified on the same date as the date entered. The files stored also include those modified since the specified date on nonsystem volume sets that are online. Use this form of the DATE parameter when you perform regular backups of a file set. Store the entire set, for example, once a week and store only those files modified since the full backup the remaining six days. Storing Files Not Accessed Since a Certain Date You can also use the DATE parameter to store only files that have not been accessed since a certain date. For example: :FILE T;DEV=TAPE :STORE @.OPERATOR.SYS;*T;DATE<=06/10/93 The year can be entered as two digits or four digits (93 or 1993). The above command stores any files in the OPERATOR group of the SYS account that have not been accessed since June 10, 1993. You may want to use this form of the DATE parameter with the PURGE parameter to remove out-of-date files from your system. Refer to the next section.
