Cp & skipping exiting files

// Redhat

I am running a cron with cp every 15 minutes.

Code:
cp /p2/arch/log/* /p2/bkp

What I need is to not to copy the file again if the filename already exists under /p2/bkp

The reason is that the file size under /p2/arch/log/ will be reduced (contents truncated), so I need to keep the files copied over for the very 1st time.

In that case, I keep the original files w/o losing the contents.

Please advise.

strclean(8)						      System Manager's Manual						       strclean(8)

NAME
strclean - Removes outdated STREAMS error log files SYNOPSIS
/usr/sbin/strclean [-d logdir] [-a age] FLAGS
Specifies a maximum age in days for the STREAMS error log files if this not the default age of 3. The value of age must be an integer greater than or less than 3. Specifies a directory for the location of the STREAMS error log files to be removed if this is not the default directory /var/adm/streams. DESCRIPTION
The strclean command cleans the STREAMS error logger directory of log files (error.mm-dd) that contain error messages sent by the STREAMS log driver (strlog). If no other directory is specified (the logdir argument), the command removes error log files in the /var/adm/streams directory. If no other age is specified (the age argument), the command removes error log files that have not been modified in 3 days. The strclean command is executed by the cron daemon on a periodic basis. EXAMPLES
To remove the day-old error log files from a directory called /tmp/streams, enter: strclean -d /tmp/streams -a 1 FILES
One or more error log file or files on which strclean operates. The mm.dd in the filename indicates the month and day of the messages con- tained in the file. RELATED INFORMATION
Commands: strerr(8), cron(8). Interfaces: strlog(7). delim off strclean(8)
