Shell scripts to back up and retore files for EBS refresh or clone

Some setup and configuration files works specifically for the EBS instance. It takes a long time or may be impossible to re-create them. It is are very important to back them up before the instance refresh or clone, and then restore the files after clone script completes. Below two scripts work for EBS R12.1.

~~~~~~~~~~~~~~~~~ Backup ~~~~~~~~~~~~~~~~~~

# backup files before the refresh    

cd $HOME/admin_scripts/backups  # where to save the backed-up files
DT=`date +"%h_%d_%y"`               # backup date

echo It will delete old backup files. Continue ? yes or no

    if [ -n "$CONTEXT_FILE" ]; then
      echo 'running'
    else
      echo 'environment variable $CONTEXT_FILE does not exit. Exit ...'
      exit 1;
    fi;

    if [ -f $CONTEXT_FILE ]; then
      echo 'starting copy ...'
    else
      echo 'CONTEXT file $CONTEXT_FILE does not exist. Exit ...'
      exit 1;
    fi

    file1=`basename $CONTEXT_FILE`
    if [ -f $file1 ]; then
      mv $file1 $file1'_'$DT      # adding the backup date
    fi
    file2=custom`basename $CONTEXT_FILE .xml`'.env'
    if [ -f $APPL_TOP/$file2 ]; then
      cp -p $APPL_TOP/$file2 .
    fi

    rm -rf Apache admin    # remove two previous backup folders 

    cp -p $CONTEXT_FILE .
    cp -rp $INST_TOP/certs/Apache .      # SSL certs
    cp -rp $TNS_ADMIN .                       # TNS names

    cp -p $APPL_TOP/admin/adkeystore.dat .
    cp -p $APPL_TOP/admin/adsign.txt .

    echo 'Done with backing up files'
    ls -altr $HOME/admin_scripts/backups
    exit 0
