自动化快照生命周期

使用create-lifecycle-policy命令创建快照生命周期策略。对于 PolicyType，请指定 EBS_SNAPSHOT_MANAGEMENT。

示例 1 – 具有两个计划的快照生命周期策略

此示例创建的快照生命周期策略可创建标签键 costcenter 的值为 115 的所有卷的快照。该策略包含两个计划。第一个计划在每天 3:00 UTC 创建快照。第二个计划在每周五 17:00 UTC 创建一个周快照。

aws dlm create-lifecycle-policy \
    --description "My volume policy" \
    --state ENABLED \
    --execution-role-arn arn:aws:iam::12345678910:role/AWSDataLifecycleManagerDefaultRole \
    --policy-details file://policyDetails.json

以下是 policyDetails.json 文件的示例。

{
    "PolicyType": "EBS_SNAPSHOT_MANAGEMENT",
    "ResourceTypes": [
        "VOLUME"
    ],
    "TargetTags": [{
        "Key": "costcenter",
        "Value": "115"
    }],
    "Schedules": [{
        "Name": "DailySnapshots",
        "TagsToAdd": [{
            "Key": "type",
            "Value": "myDailySnapshot"
        }],
        "CreateRule": {
            "Interval": 24,
            "IntervalUnit": "HOURS",
            "Times": [
                "03:00"
            ]
        },
        "RetainRule": {
            "Count": 5
        },
        "CopyTags": false
    },
    {
        "Name": "WeeklySnapshots",
        "TagsToAdd": [{
            "Key": "type",
            "Value": "myWeeklySnapshot"
        }],
        "CreateRule": {
            "CronExpression": "cron(0 17 ? * FRI *)"
        },
        "RetainRule": {
            "Count": 5
        },
        "CopyTags": false
    }
]}

如果请求成功，此命令将返回新创建的策略 ID。下面是示例输出。

{
   "PolicyId": "policy-0123456789abcdef0"
}

示例 2 - 以实例为目标并创建数据（非根）卷子集快照的快照生命周期策略

此示例创建的快照生命周期策略可从标记为 code=production 的实例创建多卷快照集。该策略仅包含一个计划。该计划不会创建标记为 code=temp 的数据卷的快照。

aws dlm create-lifecycle-policy \
    --description "My volume policy" \
    --state ENABLED \
    --execution-role-arn arn:aws:iam::12345678910:role/AWSDataLifecycleManagerDefaultRole \
    --policy-details file://policyDetails.json

以下是 policyDetails.json 文件的示例。

{
    "PolicyType": "EBS_SNAPSHOT_MANAGEMENT",
    "ResourceTypes": [
        "INSTANCE"
    ],
    "TargetTags": [{
        "Key": "code",
        "Value": "production"
    }],
    "Parameters": {
        "ExcludeDataVolumeTags": [{
            "Key": "code",
            "Value": "temp"
        }]
    },
    "Schedules": [{
        "Name": "DailySnapshots",
        "TagsToAdd": [{
            "Key": "type",
            "Value": "myDailySnapshot"
        }],
        "CreateRule": {
            "Interval": 24,
            "IntervalUnit": "HOURS",
            "Times": [
                "03:00"
            ]
        },
        "RetainRule": {
            "Count": 5
        },
        "CopyTags": false
    }
]}

如果请求成功，此命令将返回新创建的策略 ID。下面是示例输出。

{
   "PolicyId": "policy-0123456789abcdef0"
}

示例 3 - 自动执行 Outpost 资源本地快照的快照生命周期策略

此示例创建一个快照生命周期策略，该策略创建所有 Outpost 中带有 team=dev 标记的卷的快照。该策略在源卷所在的同一 Outpost 上创建快照。该策略从 12 UTC 开始每 00:00 小时创建一次快照。

aws dlm create-lifecycle-policy \
    --description "My local snapshot policy" \
    --state ENABLED \
    --execution-role-arn arn:aws:iam::12345678910:role/AWSDataLifecycleManagerDefaultRole \
    --policy-details file://policyDetails.json

以下是 policyDetails.json 文件的示例。

{
    "PolicyType": "EBS_SNAPSHOT_MANAGEMENT",
    "ResourceTypes": "VOLUME",
	"ResourceLocations": "OUTPOST",
    "TargetTags": [{
        "Key": "team",
        "Value": "dev"
    }],
    "Schedules": [{
        "Name": "on-site backup",
        "CreateRule": {
            "Interval": 12,
            "IntervalUnit": "HOURS",
            "Times": [
                "00:00"
            ],
	"Location": [
		"OUTPOST_LOCAL"
	]
        },
        "RetainRule": {
            "Count": 1
        },
        "CopyTags": false
    }
]}

示例 4 - 在区域中创建快照并将其复制到 Outpost 的快照生命周期策略

以下示例策略创建带 team=dev 标记的卷的快照。快照在源卷所在的同一区域中创建。从 12 UTC 开始，每 00:00 小时创建一次快照，并保留最多 1 个快照。该策略还会将快照复制到 Outpost arn:aws:outposts:us-east-1:123456789012:outpost/op-1234567890abcdef0，使用默认加密 KMS 密钥 对复制的快照进行加密，并将副本保留 1 个月。

aws dlm create-lifecycle-policy \
    --description "Copy snapshots to Outpost" \
    --state ENABLED \
    --execution-role-arn arn:aws:iam::12345678910:role/AWSDataLifecycleManagerDefaultRole \
    --policy-details file://policyDetails.json

以下是 policyDetails.json 文件的示例。

{
    "PolicyType": "EBS_SNAPSHOT_MANAGEMENT",
    "ResourceTypes": "VOLUME",
    "ResourceLocations": "CLOUD",
    "TargetTags": [{
        "Key": "team",
        "Value": "dev"
    }],
    "Schedules": [{
        "Name": "on-site backup",
        "CopyTags": false,
        "CreateRule": {
            "Interval": 12,
            "IntervalUnit": "HOURS",
            "Times": [
                "00:00"
            ],
            "Location": "CLOUD"
        },
        "RetainRule": {
            "Count": 1
        },
        "CrossRegionCopyRules" : [
        {
            "Target": "arn:aws:outposts:us-east-1:123456789012:outpost/op-1234567890abcdef0",
            "Encrypted": true,
            "CopyTags": true,
            "RetainRule": {
                "Interval": 1,
                "IntervalUnit": "MONTHS"
            }
        }]
    }
]}

示例 5 – 快照生命周期策略，具有已启用归档并基于期限的计划

此示例将创建一个以带有 Name=Prod 标签的卷为目标的快照生命周期策略。此策略采用基于期限的计划，该计划会在每月第一天 09:00 创建快照。此计划会在标准层中将每个快照保留一天，之后将其转移到至存档层。快照在存档层中存储 90 天后将被删除。

aws dlm create-lifecycle-policy \
    --description "Copy snapshots to Outpost" \
    --state ENABLED \
    --execution-role-arn arn:aws:iam::12345678910:role/AWSDataLifecycleManagerDefaultRole \
    --policy-details file://policyDetails.json

以下是 policyDetails.json 文件的示例。

{
    "ResourceTypes": [ "VOLUME"],
    "PolicyType": "EBS_SNAPSHOT_MANAGEMENT",
    "Schedules" : [
      {
        "Name": "sched1",
        "TagsToAdd": [
          {"Key":"createdby","Value":"dlm"}
        ],
        "CreateRule": {
          "CronExpression": "cron(0 9 1 * ? *)"
        },
        "CopyTags": true,
        "RetainRule":{
          "Interval": 1,
          "IntervalUnit": "DAYS"
        },
        "ArchiveRule": {
            "RetainRule":{
              "RetentionArchiveTier": {
                 "Interval": 90,
                 "IntervalUnit": "DAYS"
              }
            }
        }
      }
    ],
    "TargetTags": [
      {
        "Key": "Name",
        "Value": "Prod"
      }
    ]
}

示例 6 – 快照生命周期策略，具有已启用归档并基于计数的计划

此示例将创建一个以带有 Purpose=Test 标签的卷为目标的快照生命周期策略。此策略采用基于计数的计划，该计划会在每月第一天 09:00 创建快照。此计划将在快照创建后立即将其存档，并在存档层中最多保留三个快照。

aws dlm create-lifecycle-policy \
    --description "Copy snapshots to Outpost" \
    --state ENABLED \
    --execution-role-arn arn:aws:iam::12345678910:role/AWSDataLifecycleManagerDefaultRole \
    --policy-details file://policyDetails.json

以下是 policyDetails.json 文件的示例。

{
    "ResourceTypes": [ "VOLUME"],
    "PolicyType": "EBS_SNAPSHOT_MANAGEMENT",
    "Schedules" : [
      {
        "Name": "sched1",
        "TagsToAdd": [
          {"Key":"createdby","Value":"dlm"}
        ],
        "CreateRule": {
