Ahsay delivers comprehensive protection for all virtual machines (VMs) running on Proxmox VE standalone and clustered hosts, combining rapid recovery with precise restore capabilities so IT teams can handle both major outages and everyday small scale data loss incidents with confidence.
- Disaster recovery & business continuity: Restore entire VMs to replacement hosts when production servers fail or data becomes corrupted.
- Minimize downtime costs: Faster recovery means less disruption—protecting revenue streams and productivity.
- Migration flexibility: Backups can be leveraged to move VMs between hosts.
- Instant recovery: Boot VMs directly from backup storage and get critical services online within minutes, even while full recovery continues in the background—for meeting strict RTOs (Recovery Time Objectives).
- Granular restore: Recover individual files or folders from any point-in-time without restoring the entire VM. Perfect for meeting precise RPOs (Recovery Point Objectives).
Secure, reliable, and fast backups
Ahsay leverages a suite of technologies and settings to ensure data reliability and consistency, minimize backup transfer size, and boost overall performance:
- Select all VMs or specific VMs to back up.
- Choosing specific virtual disks on each VM allows customers to focus on protecting critical data, optimizing both backup performance and storage usage.
- Proxmox snapshots capture the entire state of guest VMs to ensure complete data consistency before backup.
- Application-aware backups for Windows VMs automatically flush in-memory data and pending transactions to disk, guaranteeing application-level consistency.
- Change Block Tracking (CBT) detects block-level changes on guest VMs, backing up only the blocks that have changed since the last job.
- Automatically excludes the swap file and deleted data blocks on the virtual disk(s) from the backup data.
- Data deduplication removes duplicate data, backing up only unique data, which can reduce storage usage and costs by up to 90%.
- Data compression further reduces the size of backup files.
On top of these, backing up your guest VMs with Ahsay using advanced technologies, including immutable backups, AES 256-bit encryption, two-factor authentication, and Restore Drill (backup data validation), ensures your organization can reliably recover data in the event of a disaster.
What are the benefits?
Ahsay provides an intuitive user interface to guide you through the automated recovery process directly on a live production server or standby server.
Standard recovery options:
- Restore guest VMs to the original location on the same Proxmox host.
- Restore guest VMs to an alternate storage location on the same Proxmox host.
- Restore guest VMs to an entirely different Proxmox host (standalone or cluster)
Advanced recovery options:
- Granular Restore: Mount the virtual disks of a guest VM directly from the backup file on the backup destination, then recover individual files or folders using the Windows File Explorer.
- VM Run Direct: Run a VM directly from the backup file on AhsayCBS or cloud storage without restoring it to the Proxmox host.
- Live Migration: Restore a running guest VM back to the Proxmox host with minimal downtime.
