Overview

Snapshots are point-in-time, read-only copies of your data. On ALYPOD Cloud you get snapshots on CPU Pods (disk-level) and on Storage Boxes. They are the fastest way to undo a bad change — an accidental rm, a failed upgrade or a corrupted file — without waiting for a full restore from off-site backup.

Because snapshots are stored on the same platform, treat them as a convenience layer, not your only backup. Still keep an off-site copy following the 3-2-1 rule.

Before you begin

  • A CPU Pod or Storage Box with snapshots enabled in the ALYPOD Console.
  • Enough free space on the Pod/Box to hold the snapshot.
  • Console access at account.alypod.com.

Steps

Create a snapshot

  1. Open the ALYPOD Console and go to Storage → Storage Boxes (or Compute → CPU Pods for disk snapshots).
  2. Select the resource and open the Snapshots tab.
  3. Click Create snapshot, give it a descriptive name such as before-nginx-upgrade, and confirm. Creation may take a few minutes depending on data size.

You can also create Pod disk snapshots directly from the Pod's Backups tab.

Restore a snapshot

  1. Open the Snapshots tab and select the snapshot to restore.
  2. Click Restore. On a Storage Box this replaces the current volume content with the snapshot state.
  3. For CPU Pods, use Restore to roll the disk back, or Clone to new Pod to test the snapshot without touching production.
  4. Confirm the operation and wait for it to complete. Check your files afterwards:

bash ls -la /mnt/storagebox df -h

Automate snapshots

Enable Automated snapshots with a retention policy (for example daily, keep 7). This creates rolling restore points automatically so you always have a recent one.

Troubleshooting

  • Problem: Snapshot fails with "not enough space". Solution: Remove old snapshots or free space on the volume.
  • Problem: Restore is slow on a large volume. Solution: Snapshot recovery writes many blocks; expect minutes for hundreds of GB.
  • Problem: Restore rolled back newer files. Solution: Snapshots revert the whole volume — use Clone to new Pod if you only need a few files.
