我们有一台相当大的 Windows Server 2012 R2 机器,上面运行着 Oracle 12c。我们使用 AWS MGN(应用程序迁移服务)将该本地机器迁移到 AWS。迁移已经过测试并且是成功的 - 所以我们现在有一个大型 Windows 2012 R2 EC2 实例在 AWS 上运行 Oracle 12c 服务器。
我正在尝试使用 AWS Backups 拍摄 Oracle 实例的快照,以尝试对其进行还原,作为迈向完整 DR 计划的第一步。快照恢复得很好,我们能够登录到 Windows 实例,但似乎 Oracle 表处于不一致状态,我没有从 AWS 备份中获得干净的快照。Microsoft VSS 似乎已在恢复的实例上启用。
问题是:是否有人成功使用 AWS Backups 在 Windows Server 上备份和还原 Oracle 数据库?如果是这样,我们需要做出哪些改变?我包括了一些 terraform 以供参考:
resource "aws_backup_plan" "weekly" {
name = "Legacy${var.environment_tag}Weekly"
rule {
enable_continuous_backup = false
rule_name = "Legacy${var.environment_tag}Weekly"
target_vault_name = aws_backup_vault.legacy.name
schedule = var.backup_plan_weekly_schedule
start_window = 60 # minutes
completion_window = 180 # minutes
lifecycle {
cold_storage_after = 30 # days
delete_after = 120 # days
}
copy_action {
destination_vault_arn = aws_backup_vault.legacy.arn
lifecycle {
cold_storage_after = 30 # days
delete_after = 120 # days
}
}
copy_action {
destination_vault_arn = aws_backup_vault.secondary.arn
lifecycle {
cold_storage_after = 30 # days
delete_after = 120 # days
}
}
}
advanced_backup_setting {
backup_options = {
WindowsVSS = "enabled"
}
resource_type = "EC2"
}
tags = merge(
local.tags, {
"Name" = "Legacy${var.environment_tag}Weekly"
}
)
}
resource "aws_backup_selection" "weekly" {
iam_role_arn = aws_iam_role.legacy_backup.arn
name = "Legacy${var.environment_tag}Weekly"
plan_id = aws_backup_plan.weekly.id
selection_tag {
type = "STRINGEQUALS"
key = "AWSBackup"
value = "weekly"
}
}
resource "aws_backup_vault" "legacy" {
name = "Legacy${var.environment_tag}"
kms_key_arn = aws_kms_key.mgn.arn
tags = merge(
local.tags, {
"Name" = "Legacy${var.environment_tag}"
}
)
}
