Team:
I am writing a small script to copy the home dir's
from 3 machines. Pl find my script below..Please help
if there are any mistakes..My first attempt..
#!/usr/bin/sh
###################################################################
# SCRIPT NAME : HomeBackup.sh
# AUTHOR : Brian
# DATE :
# VERSION NO : 1.0
# PURPOSE : This script takes backup of /home
Machines ns1, ns2, ns3 to /home directories to as50
server.
#
PATH=$PATH:/usr/bin:/usr/sbin:/usrlocal/bin:/usr/contrib/bin:/opt/perf/bin
export TERM=vt100
export PATH
LOG_FILE=/tmp/HomeBackup.log
exec >> $LOG_FILE 2>&1
ns1_Home_Size=`remsh ns1 /usr/bin/bdf |grep home |awk
'{ if ($6 == "/home") print $3 }'`
if [ $? -eq 1 ]
then
echo "`date '+%D %T'` ns1 remote execution permission
is not available"
exit 1
fi
ns2_Home_Size=`remsh ns2 /usr/bin/bdf |grep home |awk
'{ if ($6 == "/home") print $3 }'`
if [ $? -eq 1 ]
then
echo "`date '+%D %T'` ns2 remote execution permission
is not available"
exit 1
fi
ns3_Home_Size=`remsh ns3 /usr/bin/bdf |grep home |awk
'{ if ($6 == "/home") print $3 }'`
if [ $? -eq 1 ]
then
echo "`date '+%D %T'` ns3 remote execution permission
is not available"
exit 1
fi
Total_used_space=`expr $ns1_Home_Size + $ns2_Home_Size
+ $ns3_Home_Size`
Availed_space=`/usr/bin/bdf |grep depot|awk '{ if ($6
== "/depot") print $4 }'`
# Check free space is available on as50:/depot
if [ $Availed_space -lt $Total_used_space ]
then
echo "`date '+%D %T'` Error: There is not enough
space under /depot "
exit 1
fi
#Copy ns1 /home directory to as50:/depot/ns1
if [ -f /home/ns1/home ]
then
rcp -rp ns1/home /depot/ns1/home
fi
#Copy ns2 /home directory to as50:/depot/ns2
if [ -f /home/ns2/home ]
then
rcp -rp ns2:/home /depot/ns2/home
fi
#Copy ns3 /home directory to as50:/depot/ns3
if [ -f /home/ns3/home ]
then
rcp -rp ns3:/home /depot/ns3/home
fi
My questions:
Is rcp a good approach or can i use fbackup etc..
Is there anyhting wrong with the script?
Please Help
Best Regards
Brian
