Due to Google Cloud Platform’s (GCP) announcement of new prices for disk snapshots, as of April 1, 2023. The changes affect regional and multi-regional snapshots.

The image shows the situation in many companies where the cost of snapshots has almost doubled and it is now really important to check and analyze your snapshot protection, especially if you have a large organization and thousands of PD snapshots.

• As a suggestion to minimize costs, use Archive snapshots:
  • Use archive snapshots. Archive snapshots are a new type of snapshot that is designed to be more cost-effective than standard snapshots. Archive snapshots are stored in a compressed format and can only be accessed by creating a new disk from the snapshot. The price of archive snapshot storage is $0.019 per GB per month, which is significantly lower than the price of standard snapshot storage ($0.05 per GB per month).
  • But very important to remember about the “Early Deletion” cost – the minimum life sickle period for this type of snapshots is 90 days.

• Important steps:
  • Retention policy and snapshot frequency:
    • Review your retention policy and snapshot frequency to comply with the policy. Reducing the frequency of snapshots or adjusting the retention period can help reduce costs. Only take snapshots as often as necessary and consider deleting older snapshots that are no longer needed.
  • Use regional (rather than multi-regional) snapshots:
    • Regional snapshots are generally cheaper than multi-regional snapshots. If your use case allows it, opt for regional snapshots to save on costs.
  • Optimizing snapshot size:
    • Try to minimize the amount of data stored in the snapshots by removing unnecessary files or temporary data. If you take several snapshots from one disk, the incrementally saved data and deleted files will be added to the active snapshots. Ensuring efficient disk usage can help reduce the size of snapshots and, consequently, lower costs.
  • Snapshot Schedule and Automation:
    • Automate the snapshot creation process using scheduling tools or scripts Python. This helps you manage snapshots efficiently and avoid unnecessary manual operations.

def create_snapshot(disk_name, snapshot_name):
    config = {
        "name": snapshot_name,
        "sourceDisk": disk_name,
        "storageLocations": "southamerica-east1",
        "labels": {"bkp": "archive"}
    }
    # parâmetro 'snapshot-type' definido como 'ARCHIVE' no corpo da solicitação
    config["snapshotType"] = "ARCHIVE"

• • Choose the Right Disk Type and Size + Analyze:
    • Choose the appropriate persistent disk type and size based on your application’s needs. Using the right disk specifications can prevent overprovisioning and reduce costs.
    • Monitor and analyze snapshot usage regularly to identify any unnecessary or redundant snapshots. Removing such snapshots can lead to cost reductions.
