Key Capabilities
Persistent Volumes
Volumes exist independently of instances — data survives instance deletion, restart, and migration.
Live Resize
Extend volume capacity online without detaching or rebooting the attached instance.
Snapshots & Backups
Point-in-time crash-consistent snapshots and incremental backups to protect critical data.
Storage Tiers
NVMe, SSD, and HDD-backed volume types with defined IOPS and throughput guarantees for every workload class.
Volume Encryption
Transparent at-rest encryption backed by the Polystack Key Management service — no application changes required.
Cross-Project Transfers
Transfer volume ownership between projects with a secure token-based handoff workflow.
