Aws backup plan multiple selection_tags
问题
我有一个问题，我已经研究了几个小时，但仍然没有得到一个合适的答案。
我正在terraform中定义一个aws_backup_plan。
module "backup" {
count = var.backup_enabled ? 1 : 0
source = "somwthing/backup/aws"
enabled = var.backup_enabled
version = "0.13.1"
namespace = "sr"
stage = var.stage
name = "storage-backups"
tags = var.tags
schedule = "cron(0 10 ? * * *)" # At 10:00 AM, daily
iam_role_name = local.iam_role_name # unique role name per region as IAM resources are global
delete_after = 35 # cannot be bigger than 35 days
enable_continuous_backup = true
backup_resources = var.backup_resources
selection_tags = [
{ type = "STRINGEQUALS", key = "backup", value = "weekly" },
{ type = "STRINGEQUALS", key = "backup", value = "daily" }
]
}
我刚刚添加了 { type = "STRINGEQUALS", key = "backup", value = "daily" } 到 selection_tags。我的问题是，如果我对一个资源打上数组中的一个标签，它会被分配给备份计划吗？也就是说，这个数组是否像一个OR运算符一样工作？

I have a question that I have been researching for a few hours now but still didn't manage to get a proper answer.
I'm defining an aws_backup_plan in terraform.
module "backup" {
count = var.backup_enabled ? 1 : 0
source = "somwthing/backup/aws"
enabled = var.backup_enabled
version = "0.13.1"
namespace = "sr"
stage = var.stage
name = "storage-backups"
tags = var.tags
schedule = "cron(0 10 ? * * *)" # At 10:00 AM, daily
iam_role_name = local.iam_role_name # unique role name per region as IAM resources are global
delete_after = 35 # cannot be bigger than 35 days
enable_continuous_backup = true
backup_resources = var.backup_resources
selection_tags = [
{ type = "STRINGEQUALS", key = "backup", value = "weekly" },
{ type = "STRINGEQUALS", key = "backup", value = "daily" }
]
}
I have just added { type = "STRINGEQUALS", key = "backup", value = "daily" } to the selection_tags. My question is, if I tag one resource with one of the tags in the array does it get assigned the backup plan? I.e. does this array behave like an OR operator?

这取决于条件的编写方式，在这个特定示例中，它的行为类似于“AND”语句而不是“OR”语句。这是为了在创建计划时提供精细的定位机制而设计的。
请查看来自AWS备份的这个图像：

Well it depends on how condition was written, In this particular example it behaves like an AND statement rather an OR. This was designed to provide refined targeting mechanisms when creating plans.
