Re: script to cp a DIR to DISK runing it using cron job

Hi:

This could be as simple as a crontab entry like:

0 17 * * cp -Rp /disk1/dir1 /disk1/dir2 /disk1/dir3 /disk2 && echo OK || echo FAILED

Regards!

Re: script to cp a DIR to DISK runing it using cron job

The definition of disk on HPUX is a little bit fuzzy as the use of LVM is default behavior and one LVM volume can be spread over several physical disks.

Having said that, let's assume your "disk" is mounted on /new_disk filesystem and you want to copy the contetns of /data/dir1, /data/dir2 and /data/dir3 onto this /new_disk filesystem

you just create a script, let's say, /var/adm/datacopier.sh as follows:

#!/usr/bin/ksh
timestamp=`date | awk {'print $2 $3 $6'}`
for dir in /data/dir1 /data/dir2 /data/dir3
do
cp -rp ${dir} /new_disk/somedir/${dir}.${timestamp}
done

save and exit. Make sure it is executable by the person/group according to its file permissions.

then edit your crontab via command crontab -e and append this line

0 3 * * * /var/adm/datacopier.sh > /var/adm/datacopier.log 2>&1

Now, everyday at 3 AM, your directories will be copied to the destination disk and they will have a timestamp on them, in case you want to copy more than one day's worth.

Hope this helps

Hi:

> thank you . now, will this overwrite the data daily?

In the simple script I suggested, yes. In Mel's method, no, since he appends a date (e.g. May132009) to each destination directory name.
