It may be a foolish method, but you can try this:

# ls -l | grep "Oct 30" | awk '{print $NF}' | tar -cvf [Tape Drive]

Hello

You can try that...

sample))
# tar cvf - `ls -l | grep "Oct 30" | awk '{print $9}'` | dd of=/dev/rmt/0m bs=128k

"tar" can execute interprocess communication with only "dd".

you could use also:

ls -l | grep "Oct 30" | awk '{print $NF}' | cpio -o > /dev/rmt/cxtxdx ( tape device)

Alternately, you can use a command like:

find / -mtime 10 | xargs tar cvf /dev/rmt/xxxx

which will tar all files on your system
having been modified in exactly 10 days.

Use atime for files being accessed..

The disadvantage is that you have to compute
the number of days but this can easily be
done by a shell or perl script, allowing
to replace the fixed figure by a variable.

Only as an addition to Dan's reply,
if you already use Perl for the date conversion stuff I'd do the filesystem scour from within Perl as well, using Perl's standard File::Find module and define in two lines a callback sub reference.
