VMのバックアップ保存先にバックアップを行うシェルスクリプトを作成する StoreNAS-Backup-Mintというディレクトリに作成する（もともと誰かがbackup.shを作ってくれていた）

[root@mint:~] ls /vmfs/volumes/StoreNAS-Backup-Mint
#recycle         20200205_backup  backup.sh        rancher-0.tmp

シェルスクリプト作成¶

使用できるコマンドの確認

[root@mint:~] ls -la /bin/sh
lrwxrwxrwx    1 root     root            35 Jun 18  2019 /bin/sh -> /usr/lib/vmware/busybox/bin/busybox

busyboxで使用できるコマンドをシェルスクリプトで使用可能バックアップを行うbackup.shを/vmfs/volumes/StoreNAS-Backup-Mint/backupに作成する動作確認のためcatを用いてテスト用シェルスクリプト作成参考資料：https://mseeeen.msen.jp/configure-cron-on-vmware-esxi-6-7/

backup.sh

target_dirs=`find /vmfs/volumes/StoreNAS-Mint/ -type d`

for target in $target_dirs
do
  echo cp -r $target /vmfs/volumes/StoreNAS-Backup-Mint/backup/
done

実行結果

[root@mint:/vmfs/volumes/29f92888-f2d38ff8/backup] chmod u+x backup.sh
[root@mint:/vmfs/volumes/29f92888-f2d38ff8/backup] ls

テストは成功

実際にバックアップで実行するバックアップファイルに変更

backup.sh

##
# create backup
##
date_dir="$(date +%Y-%m-%d-%H-%M)"
echo "date_dir=$date_dir"
mkdir /vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir
vim-cmd vmsvc/getallvms | grep -v Name | grep StoreNAS-Mint | awk "{print \$2;}" | while read vm_name
do
  echo "vm_name=$vm_name"
  # get virtual machine id
  vm_id=$(vim-cmd vmsvc/getallvms | grep "$vm_name" | grep StoreNAS-Mint | awk "{print \$1;}")
  echo "vm_id=$vm_id"
  # create a snapshot
  vim-cmd vmsvc/snapshot.create $vm_id $vm_name
  # create dir
  mkdir "/vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir/$vm_name"
  # copy backup vmdisc
  vmkfstools -i "/vmfs/volumes/StoreNAS-Mint/$vm_name/$vm_name.vmdk" -d thin "/vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir/$vm_name/$vm_name.vmdk"
  # delete snapshot
  vim-cmd vmsvc/snapshot.removeall $vm_id
  # copy backup file
  find /vmfs/volumes/StoreNAS-Mint/"$vm_name"/* -not -name "*.vmdk" -exec cp {} /vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir/"$vm_name"/ \;
done
############# ここからStorePCIeのVMのバックアップコードの追加
vim-cmd vmsvc/getallvms | grep -v Name | grep StorePCIe | awk "{print \$2;}" | while read vm_name
do
  echo "vm_name=$vm_name"
  # get virtual machine id
  vm_id=$(vim-cmd vmsvc/getallvms | grep "$vm_name" | grep StorePCIe | awk "{print \$1;}")
  echo "vm_id=$vm_id"
  # create a snapshot
  vim-cmd vmsvc/snapshot.create $vm_id $vm_name
  # create dir
  mkdir "/vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir/$vm_name"
  # copy backup vmdisc
  vmkfstools -i "/vmfs/volumes/StorePCIe/$vm_name/$vm_name.vmdk" -d thin "/vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir/$vm_name/$vm_name.vmdk"
  # delete snapshot
  vim-cmd vmsvc/snapshot.removeall $vm_id
  # copy backup file
  find /vmfs/volumes/StorePCIe/"$vm_name"/* -not -name "*.vmdk" -exec cp {} /vmfs/volumes/StoreNAS-Backup-Mint/backup/$date_dir/"$vm_name"/ \;
done
##
# delete old backup files
##
# keep latest 3 versions
ls -r /vmfs/volumes/StoreNAS-Backup-Mint/backup | tail -n+4 | xargs -I{} rm -fr /vmfs/volumes/StoreNAS-Backup-Mint/backup/{}

実行はVMの電源を落とさないと最初の一回はスナップショットを取れないため次回に回す

実行確認¶

sshが切れても実行し続けるためproxyで実行する

ssh cdsl
ssh proxy
tmux

この状態で実行を行うことでsshを抜けても実行し続けられる Ctrl+B, D で抜けることができるまた戻るときは tmux a で戻る

2021/10/7¶

リストアの確認¶

anchor-2を例としてリストアしてみる - anchor-2のシャットダウン - anchor-2のアクションから登録解除 - 仮想マシンの登録でStoreNAS-Backup-Mintからバックアップしたファイルをもとにリストアする - 新しく登録したanchor-2をパワーオン - ログインできたか確かめるバックアップがちゃんとできていることが確認できた

cronの設定¶

cronにシェルスクリプトを追加することにより自動で定期的に実行してくれる

/var/spool/cron/crontabs/に移動 chmod 1744 /var/spool/cron/crontabs/rootで権限付与 vi /var/spool/cron/crontabs/rootで書き込む

#min hour day mon dow command
1    1    *   *   *   /sbin/tmpwatch.py
1    *    *   *   *   /sbin/auto-backup.sh
0    *    *   *   *   /usr/lib/vmware/vmksummary/log-heartbeat.py
*/5  *    *   *   *   /bin/hostd-probe.sh ++group=host/vim/vmvisor/hostd-probe/stats/sh
00   1    *   *   *   localcli storage core device purge
00   0    *   *   *   /vmfs/volumes/StoreNAS-Backup-Mint/backup.sh

再起動するとcronが初期化されるので、起動時にcronの設定を再度追加するため以下のファイルに書き込む /etc/rc.local.d/local.sh

/etc/rc.local.d/local.sh

#!/bin/sh

# local configuration options

# Note: modify at your own risk!  If you do/use anything in this
# script that is not part of a stable API (relying on files to be in
# specific places, specific tools, specific output, etc) there is a
# possibility you will end up with a broken system after patching or
# upgrading.  Changes are not supported unless under direction of
# VMware support.

# Note: This script will not be run when UEFI secure boot is enabled.

/bin/echo "00   0    *   *   *   /vmfs/volumes/StoreNAS-Backup-Mint/backup.sh" >> /var/spool/cron/crontabs/root
/bin/kill $(cat /var/run/crond.pid)
/usr/lib/vmware/busybox/bin/busybox crond

exit 0
