Hi,

I want to do incremental backup of my files,
I am using cpio for copy,
my code is as follows:

CPIO=/usr/bin/cpio

cd /home/arbuser/temp2/mscdr/tar/daily.0 && find . -print | $CPIO -dplm $DR_BACKUP_DIR/daily.1


I am unable to copy to daily.1

in commad prompt I am gettiung error:
cannot write in </home/arbuser/temp2/mscdr/tar/daily.1>

I have created daily.1 and gave permisstion attribute to 777, still I am gettinf same error.

You are doing a cpio -p which tries to copy a file tree rather than create a cpio archive. The -p option is clearly documented as needing a destination directory. You are giving it a destination file.

Hi,

my Code :
echo copping daily.0 to daily1.0 using cpio
cd /home/arbuser/temp2/mscdr/tar/daily.0 && find . -print | $CPIO -pdl "$DR_BACKUP_DIR/daily.1/";
echo "Error==> " $?


O/p :

copping daily.0 to daily1.0 using cpio
cannot write in </home/arbuser/temp2/mscdr/tar/daily.1/>
Error==> 2

what is wrong in my code??

Most people backup to an archive file. If your destination is a writable directory, this should work. I tried your code on my system but with with different directories and it worked for me. Can you write into that directory? Try touching a file in it using the full path name, not a relative pathname. An unsearchable directory anywhere in that destination path could cause this. Other than that, it beats me.
