EBS Snapshotshigh

• Per-EBS volume, incremental in S3; not full instance image.
• Via EC2 CreateSnapshot API, not Nova/Cinder.
• Async pending state, volume usable during snapshot.
• Billed per GB-month stored.

Snapshotshigh

• Snapshots of managed disks (Microsoft.Compute/snapshots), billed on used size, separate from volumes unlike Cinder volume snapshots integration.
• Supports incremental snapshots for efficiency, ZRS storage in zones.
• API /providers/Microsoft.Compute/snapshots vs Nova/Cinder volume snapshot APIs.
• Primarily for disks, not full instances; instance snapshots via images instead.

Volume Snapshotshigh

• Proprietary API /v2/volumes/{volume_id}/snapshots instead of OpenStack /v3/{project_id}/snapshots.
• Explicitly crash-consistent only, no automatic filesystem consistency (requires manual power-off/sync); OpenStack snapshots can use quiescing drivers for apps like databases.
• Snapshots billed separately based on block-level used size (may exceed filesystem due to trim); OpenStack typically similar. See the DigitalOcean pricing page for current rates.
• Can create new volumes only in same region as snapshot; OpenStack snapshots more flexible for cross-region with upload/download.

Standard/Archive Snapshotshigh

• Crash-consistent point-in-time copies stored incrementally in Cloud Storage (geo-redundant by default), unlike Cinder snapshots which depend on backend (often full copies).
• Two types: Standard (faster recovery) and Archive (cheaper long-term); supports snapshot schedules (standard only).
• Global by default, shareable across projects/regions/zones with network egress costs for cross-region restore; regional scoping (preview) for location control.
• Frequency limit: max 6 snapshots per disk every 60 minutes.

N/A (No equivalent)high

• No support for volume snapshots in API or console; explicitly stated 'we do not provide Backups or Snapshots for Volumes' and server snapshots exclude volumes.
• Workarounds like rsync/dd to new volume required, unlike Cinder's create/delete/get/manage_snapshot API.
• Recent confirmations (2026) show no addition of feature.
• Created as Image type='snapshot' via server action; stored under /images.
