i have to touch the file because we have some processes running that need to pick that blank file otherwise we need to restart the aaplication again if i deleted the file without touching it.cp will unnecessarily increase the size.
What about moving the file and touching a new one:
Code:
for file in `ls *log*`
do
    mv $file $file.`date +%a` && touch $file || echo "Can not backup $file";
done

NAME

       touch - change file timestamps

SYNOPSIS

       touch [OPTION]... FILE...

DESCRIPTION

       Update the access and modification times of each FILE to the current time.

       Mandatory arguments to long options are mandatory for short options too.

       -a     change only the access time

       -B, --backward=SECONDS
	      Modify  the time by going back SECONDS seconds.  For example, touch -r foo -B 5 bar will make the file bar 5 seconds older than file
	      foo.

       -c, --no-create
	      do not create any files

       -d, --date=STRING
	      parse STRING and use it instead of current time

       -F, --forward=SECONDS
	      Modify the time by going forward SECONDS seconds.  For example, touch -r foo -F 5 bar will make the file bar 5  seconds  newer  than
	      file foo.

       -f     (ignored)

       -m     change only the modification time

       -r, --reference=FILE
	      use this file's times instead of current time

       -t STAMP
	      use [[CC]YY]MMDDhhmm[.ss] instead of current time

       --time=WORD
	      set time given by WORD: access atime use (same as -a) modify mtime (same as -m)

       --help display this help and exit

       --version
	      output version information and exit

       Note that the -d and -t options accept different time-date formats.
