HuaweiCloud CBR Terraform Module

Terraform module which creates CBR (Cloud Backup and Recovery) resources on HuaweiCloud.

Usage

module "cbr" {
  source = "github.com/artifactsystems/terraform-huawei-cbr?ref=v1.0.0"

  vault_name      = "my-backup-vault"
  vault_type      = "disk"
  protection_type = "backup"
  vault_size      = 100
  auto_expand     = true

  volume_ids = [
    "volume-id-1",
    "volume-id-2"
  ]

  # Simple backup policy - daily backup at 2 AM
  backup_cycle_interval = 1
  execution_times        = ["02:00"]
  backup_quantity       = 7 # Keep last 7 backups

  tags = {
    Terraform   = "true"
    Environment = "dev"
  }
}

• ✅ Long-term Retention: Advanced retention rules with daily/weekly/monthly/yearly backups
• ✅ Auto-expand: Automatic vault capacity expansion when needed
• ✅ Multi-AZ: Multi-availability zone backup support for high availability

Backup Scheduling

• ✅ Flexible Scheduling: Daily or interval-based backup schedules
• ✅ Multiple Execution Times: Configure multiple backup times per day
• ✅ Weekly Schedule: Day-of-week based scheduling (MO, TU, WE, TH, FR, SA, SU)

Retention & Lifecycle

• ✅ Quantity-based Retention: Retain backups by count (2-99,999 backups)
• ✅ Time-based Retention: Retain backups by duration (2-99,999 days)
• ✅ Long-term Retention Rules: Daily, weekly, monthly, and yearly backup retention
• ✅ Full Backup Interval: Configurable full backup frequency after incremental backups

Resource Management

• ✅ Disk Backup: Backup specific EVS volumes (disk type vault)
• ✅ Server Backup: Backup entire ECS instances with volume exclusion support (server type vault)
• ✅ Auto-bind: Automatic resource association based on tags
• ✅ Vault Set Resource: Separate resource management for fine-grained control

Replication

• ✅ Cross-region Replication: Replicate backups to different regions
• ✅ Cross-project Replication: Replicate backups to different projects
• ✅ Replication Acceleration: Enable acceleration for faster cross-region replication

Billing & Operations

• ✅ Charging Modes: PrePaid and PostPaid billing options
• ✅ Auto-renew: Automatic renewal for PrePaid vaults
• ✅ Vault Locking: Protection against accidental deletion
• ✅ Backup Name Prefix: Customizable naming for automatic backups

Security & Compliance

• ✅ Enterprise Project Integration: Support for HuaweiCloud Enterprise Projects
• ✅ Consistent Levels: Crash-consistent and app-consistent backup levels (for server type)

Examples

• simple - Simple disk backup vault with basic policy configuration
• complete - Complete disk backup vault with long-term retention rules and advanced scheduling
• server - ECS server backup vault with crash-consistent or app-consistent backup
