Backing up selected files by date

The following examples pertain to the z/OS® shell only, and demonstrate how to back up selected files that may have been modified within a specified number of days. To do this you create a "find" command that returns the list of files that meet the specified criteria, and then use the output from this command as the list of files input to pax.

Example: To back up all files in the directory /u/source that have been modified in the last week, issue:

pax -wzvf backup.pax.Z    $( find /u/source -type f -mtime -8 )

Example: To back up all files in the directory /u/usrtools/ that have not been accessed in the last 100 days, issue:

pax -wzvf backup.pax.Z    $( find /u/usrtools -type f -atime +100 )

Note: The tar equivalent for the pax portion of the previous commands is:

tar -czUvf backup.pax.Z
