====== Docker Container Backup/Restore ======
  * 備份正在運行 Docker Container 的語法: docker export <CONTAINER_ID|NAME> > <CONTAINER_ID|NAME>-backup.tar<code sh>
docker export CentOS6 > /backup/CentOS6-backup.tar
</code>
  * 還原已備份的 Docker Container 的語法 : docker import - <USERID/CONTAINER_ID|NAME>-backup < <CONTAINER_ID|NAME>-backup.tar<code sh>
docker import - tryweb/centos6-backup < /backup/CentOS6-backup.tar
docker images | grep centos6-backup
docker run -i -t --name="CentOS6-01" tryweb/centos6-backup /bin/bash
</code>
  * 可以定期自動備份 <code sh>
export NOWDT=`date +%F_%T`
docker export CentOS6 > /backup/CentOS6-backup-$NOWDT.tar
rm -f /backup/CentOS6-backup.tar
ln -s /backup/CentOS6-backup-$NOWDT.tar /backup/CentOS6-backup.tar
</code>
  * 定期復原驗證 <code sh>
docker stop CentOS6-01
docker rm CentOS6-01
docker rmi tryweb/centos6-backup
docker import - tryweb/centos6-backup < /backup/CentOS6-backup.tar
docker run -i -t --name="CentOS6-01" tryweb/centos6-backup /bin/bash
</code>
