ESXi オンラインバックアップ

前提 †

オンラインでバックアップ
PCIパススルーを設定している仮想マシンはオフラインでしか取れない。

やり方 †

 バックアップ用スクリプトの使い方説明（英語）
 https://github.com/lamw/ghettoVCB

以下のサイトからバックアップ用スクリプトをダウンロードする
　バックアップスクリプト（ghettoVCB.sh）
　https://github.com/lamw/ghettoVCB/archive/master.zip
ESXiから見えるバックアップ先のメディアを用意する
　　SATAに接続したHDD、iSCSI、NFSなど

解凍＆展開

# cd /vmfs/volumes/datastore1/~
# unzip ghettoVCB-master.zip~
# mv ghettoVCB-master ghettoVCB~
# cd ghettoVCB~

設定ファイル編集

# vi ghettoVCB.conf
VM_BACKUP_VOLUME=/vmfs/volumes/ESXI_BACKUP/DAILY/ghettoVCB  #バックアップ保存先
VM_BACKUP_ROTATION_COUNT=3                                  #バックアップは3世代~

バックアップ対象の仮想マシン名を記述
```
# vi backup_vmlist.txt
WEB
MAIL
```

オンラインバックアップの実行

# ./ghettoVCB.sh -f ./backup_vmlist.txt -g ./ghettoVCB.conf

cronの設定 †

注意

linuxのcronと違い、ESXiを再起動するとcron設定が初期化される。
そのため、/etc/rc.localにESXiを再起動するたびにcron設定をするように変更をする。

以下、現時点のMy自宅鯖の設定内容

#vi /etc/rc.local
#! /bin/sh

rcdir="$1"
if [ -z "${rcdir}" ] ; then
   rcdir=/etc/rc.local.d
fi

export PATH=/sbin:/bin

log() {
   echo "$1"
   logger init "$1"
   esxcfg-init --set-boot-status-text "$1"
   esxcfg-init --set-boot-progress step
}

# execute all services registered in ${rcdir}
if [ -d "${rcdir}" ] ; then
   for filename in $(find ${rcdir} -type f -not -name ".*" | sort) ; do
      if [ -f "${filename}" ] && [ -x "${filename}" ]; then
         log "Running $(basename ${filename})"
         "${filename}"
      fi
   done
fi
