Service Console에서도 Virtual Machine Online Backup이 가능할까?
앞서 vcb관련 내용을 포스트 했는데,,
여기서 설명하는 내용은 vmdk 파일 자체를 백업 받는 방법입니다.

ESX 2.5.x 인 경우

1. vmAddRedo.pl     # Snapshot 생성
2. vmkfstools -i source.vmdk /vmfs/backup/target.vmdk
3. vmCommit.pl       # Snapshot 제거

# vmware-cmd -l
/root/vmware/win2k3/win2k3.vmx
/root/vmware/win2k/win2k.vmx

# vmAddRedo.pl -c /root/vmware/win2k3/win2k3.vmx
vmAddRedo: VM config file is '/root/vmware/win2k3/win2k3.vmx'

vmAddRedo: Disks found that are in use:
vmAddRedo: Disk found: scsi0:0 (localvmfs:win2k3.vmdk)
vmAddRedo:    1: scsi0:0
vmAddRedo: Creating the RedoLogs for cfg : /root/vmware/win2k3/win2k3.vmx
vmAddRedo:    scsi0:0:Adding REDO
vmAddRedo: diskname :/vmfs/localvmfs/win2k3.vmdk

# grep vmdk /root/vmware/win2k3/win2k3.vmx
scsi0:0.name = "localvmfs:win2k3.vmdk"

# vmkfstools -i /vmfs/localvmfs/win2k3.vmdk /vmfs/backup/win2k3.vmdk

# vmCommit.pl -c /root/vmware/win2k3/win2k3.vmx

vmCommit: VM config file is '/root/vmware/win2k3/win2k3.vmx'

vmCommit: Disks found that are in use:
vmCommit: Disk found: scsi0:0 (localvmfs:win2k3.vmdk)
vmCommit:    1: scsi0:0
vmCommit: Backing up the cfg : /root/vmware/win2k3/win2k3.vmx

vmCommit: scsi0:0: Adding stacked REDO.REDO
vmCommitRedo: diskname :/vmfs/localvmfs/win2k3.vmdk
vmCommit: scsi0:0: Committing REDO
Please wait, committing disks...
vmCommit: scsi0:0: Committing REDO.REDO


VI3 인 경우

1. vmware-cmd ${vm} createsnapshot ${vmname}-snapshot
2. vmkfstools -i source.vmdk /vmfs/volumes/backup/target.vmdk
3. vmware-cmd ${vm} removesnapshots

아래 스크립트는 참고만 하시고,, 그대로 사용하시면 안됩니다.
