I need your help in cloning 28TB xfs filesystem I used the following script:

/ >> /backuptacs.log

And the script is:

echo "++++++++++++++++ Start Date is `date`+++++++++++++ "
cd /tacs1/conq/hhl_imgs
find . -depth -print | cpio -pdmv /tacs2/conq/hhl_imgs
echo "++++++++++++++++ Completion Date is `date`+++++++++"
echo "========================================================"

With 31 GB of free memory when I run the above script I noticed too mush usage of memory. In two hours time free memory dropped to 23 GB. I can see from top that 8 GB is used and keep increasing.

What process is using the memory? Or is it cache? – psusi Feb 27 '12 at 15:52
more than 20 processes cpio - smb etc – AlBouazizi Feb 27 '12 at 16:08
Why are you running the script 20 times? – psusi Feb 28 '12 at 1:08
Sorry, only one process for cpio and one process for find and the other process are different one.. – AlBouazizi Feb 28 '12 at 5:13
