如何安排AWS EC2 Windows实例的自动(每日)快照？

AWS Powershell工具使创建快照变得非常容易：

New-EC2Snapshot "vol-371acd04" -Description "My Snapshot"

您可以像这样查询快照：

PS C:Program Files (x86)AWS ToolsPowerShell> Get-EC2Snapshot | more


SnapshotId  : snap-18be2b28
VolumeId    : vol-371acd04
Status      : completed
StartTime   : 2012-12-28T08:17:00.000Z
Progress    : 100%
OwnerId     : 383816850479
VolumeSize  : 30
Description : My Snapshot
OwnerAlias  :
Tag         : {}

确保安装了AWS Powershell工具,并创建一个计划任务,该任务使用类似于上面代码段的powershell脚本来安排快照,您应该做得很好.

已更新以查询附加的EBS卷：

要查询附加到您的实例的EBS卷,然后为每个卷创建快照,您可以执行以下操作：

# Find my instance ID from the EC2 metadata
$myInstanceID = (New-Object System.Net.WebClient).DownloadString("http://169.254.169.254/latest/meta-data/instance-id")

# Query for volumes that are attached to my Instance Id
$volumes = (Get-EC2Volume).Attachment | where {$_.InstanceId -eq $myInstanceID } | Select VolumeId

# Iterate through these volumes and snapshot each of them
foreach ($volume in $volumes)
{
    New-EC2Snapshot $volume.VolumeId -Description "My Snapshot"
}
