最新版 Zerto Virtual Replication 10 更新於 2024/5/12
Virtual Replication 採用Hypervisor層複製機制,擺脫特定硬體依賴,提供自動化災難備援設定執行工具。其控制臺嵌入在vCenter中,管理者可從單一介面設定與監控整個環境中個別虛擬機器,或保護群組的複製作業。
利用虛擬平臺是建立災難備援環境的一種方便、節省成本的方式,而為了在備援站點取得主站點資料的複本,透過複製軟體在兩站點間維持資料同步是常見的做法。這款Zerto Virtual Replication採用的是Hypervisor層複製機制,透過在虛擬平臺Hypervisor安裝一臺執行複製工作的虛擬機器,從而在兩個站點間維持資料的同步。
Zerto Virtual Replication可支援VMware ESX/ESXi 4以上環境,並能在VMFS、RDM等不同模式的磁碟區之間執行資料複製。藉由嵌入在vCenter中的管理控制臺,管理者可在不同站點的VMware主機上設定保護群組與複製路徑,控制臺還含有啟動備援系統與執行災難備援演練的選項。
Zerto Virtual Replication的複製作業為含有Journal log的處理型式,可保存寫入I/O的時間資料,從而達到接近連續資料保護(CDP)的效果,允許以10秒為單位,讓使用者將來源磁碟區回復到過去的任一時間點。

VM Level Business Continuity and Disaster Recovery (BC/ DR) for VMware Just Got Easier
Automated data recovery, failover and failback: Select any VM in VMware’s vCenter, click the Zerto tab and it’s protected. It’s that simple – no storage configuration necessary, no agent installation on guest required.
Zerto protects at the VM and VMDK level, which means that protection decisions can be made without any storage constraints.
- Replicate single or multiple VMs
- Use an intuitive GUI embedded in VMware’s vCenter
- Protect multiple virtual disks connected to the same VM
- Recover immediately with the click of a button
- Support replication of RDM devices
- View and manage local and remote sites from the same vCenter
- Deliver consistent protection across your company with the ability to support multiple sites
Enterprise-Class Replication
Zerto was designed to replace array-based replication. It provides the flexibility, scalability and ease of use expected in the virtual world without compromising any of the features and functionality required for protecting mission-critical production applications.
- Achieve seconds of RPO with continuous replication
- Recover applications instantly and automatically, providing RTO of minutes
- Protect thousands of VMs with scale-out replication architecture
- Reduce application performance impact to zero by eliminating snapshots
- Recover from logical or operator errors with journal-based, point-in-time recovery
- Monitor and report with built-in reporting and performance UI
- Centralized management simplifies tasks, ensuring application availability
Multi-tier Application Protection & Recovery
Protect applications, not LUNs! With Zerto’s Virtual Protection Groups (VPGs), you can group VMs and virtual disks to be protected and recovered together. This provides complete consistency, regardless of physical location on servers and storage.
- Group VMs and virtual disks into VPGs
- Maintain all properties of VPGs, VMs and vApps
- Test recovery, failover and failback of entire VPGs
- Support VMotion, storage VMotion, DRS and HA while replicating
- Get application protection policy and QoS
- Leverage built-in support for VSS and VMware vApp objects
Complete BC/DR: Replication, Testing, Recovery, CDP, Migration, Reporting
Zerto eliminates the need to use multiple solutions for your business continuity and disaster recovery needs. All required workflows and functionality are built-in with easy-to-follow, scalable wizards, empowering you to:
- Failover one or more VPGs through automated failback
- Recover to a historic point-in-time with journal-based CDP
- Recover applications instantly, in full read-write mode
- Test failover, including full remote recovery in a sandboxed zone
- Migrate workloads to a remote datacenter
- Monitor with comprehensive reporting on all system-wide activities

Hypervisor-Based Replication
At the heart of Zerto’s patent-pending replication technology is the Zerto Virtual Replication Appliance (VRA). A single, software-based VRA is quickly installed on each host, capable of protecting all the VMs on that host. The VRA continuously replicates data from VMs and VMDKs selected by the user, compressing it and sending it to the remote site over WAN. Replication is performed in a nearsynchronous manner without a snapshot or CBT mechanism, avoiding any negative impact on application performance. VRAs on different hosts communicate between themselves, synchronizing replication to ensure block-level consistency between different VMs located on different hosts and storage arrays. Hypervisor-based replication is fully agnostic to storage source and destination,natively supporting all virtualization platform features including VMotion,storage VMotion, high availability, clustering and more.
Cloud-Ready Disaster Recovery
Disaster recovery to the cloud is considered by many enterprises as a natural first step in the journey to the cloud, being an effective alternative to in-house DR sites.
Zerto’s technology fits perfectly with the specific needs of both enterprises and cloud
providers.
- Replication from any storage to any storage
- Management API
- Built-in WAN optimization
- Native multi-tenancy support
- Software only, highly scalable
- Tier-one protection level
