To ensure reliable protection and near-instant recovery of your virtual environment, NAKIVO Backup & Replication is able to create and maintain identical copies of your source VMs on a target ESXi host. The VM copy, also known as a replica, remains in a powered-off state, consuming no resources, and is available from your VMware vSphere client. In case of disaster, you can simply fail over to your replicas and continue business operations as usual.
NAKIVO Backup & Replication offers advanced features for automating VMware replication. You can set up policy-based replication jobs which protect VMs matching certain parameters (size, name, location, etc.). The software scans your infrastructure for new VMs and automatically adds them to the relevant replication jobs if any are discovered. You can also replicate entire VMware containers (such as resource pools, folders, hosts, clusters, etc.) and have all the VMs in a particular container automatically included in the replication job. With either of these methods, you can ensure that all your critical VMs are protected without having to track their protection status manually.
Increase VMware Replication Speed
Depending on the purpose, VMware VMs can house great amounts of data. VMware replication in this case creates additional load on your production networks and requires some time to complete, resulting in delays in business operations, affecting replication performance. NAKIVO Backup & Replication helps minimize such impact, thanks to its LAN-free data transfer and Network Acceleration. The combination of these features allows you to achieve up to 2x higher replication speed.
Save Space and Increase Reliability of Your Servers
During the replication of VMs running Microsoft SQL or Exchange Server, transaction logs are replicated alongside all the important database and application data. Transaction log files are constantly growing and accumulating, filling up the disk space, which can eventually lead to a server crash or data loss. To avoid such an occurrence, NAKIVO Backup & Replication truncates transaction logs on a source virtual machine once they reach the target host. This allows you to maintain all transaction records, save storage space, and thus safeguard your servers from failures.
Guarantee Recoverability of Your Replicas
Having replicas does not always equal successful failover and recovery. Replicas can be rendered unavailable or not bootable for a number of reasons, without necessarily meaning that the replication job was improperly performed. However, with NAKIVO Backup & Replication, you can get confirmation that your replicas are usable for recovery. The software can boot your VMware VM replicas in test mode with networking turned off, and send you a screenshot report, proving recoverability of your replicas.
Recover Faster with Automated Failover and Failback
During a disaster, all of your virtual infrastructure can be failed over from the primary site to a disaster recovery site in just a few clicks. When the virtual infrastructure at the primary site is restored, you may want to return workloads with the failback process. Using NAKIVO Backup & Replication, you can easily transfer changed data back to your primary site and resume regular business operations.
Achieve the Lowest RPO and RTO
TVM replication protects your business-critical services from a number of problems that can occur in a data center, including critical VM loss/failure due to a bad OS update, virus, or accidental deletion; host/datastore failure as a result of power loss, hardware malfunction, or infrastructure damage; or natural disasters such as earthquakes, floods, tornados, hurricanes, or typhoons.
With VM replicas in place, you can restore your business activities near-instantly, with little-to-no data loss. NAKIVO Backup & Replication enables you to reduce your recovery point objective (RPO), which is the measure of how far back in time your VMs are reverted in case of disaster. You can set up your replication jobs to run as often as every minute, thus obtaining nearly real-time replication and one of the shortest RPOs possible.
You can also significantly decrease your recovery time objective (RTO), which reflects how much time you can afford to spend waiting to restore your VMware virtual infrastructure. Since your VM replicas are regular VMware VMs, you can near-instantly fail over from the source VM to the copies, achieving dramatically better recovery times when compared to restoring them from VM backups.
Support for Applications and Databases
To create replicas of VMware VMs, NAKIVO Backup & Replication can use the application-aware replication mode. Unlike the crash-consistent mode, the application-aware mode uses Microsoft’s VSS service to correctly quiesce MS Exchange, SQL, and Active Directory data. This functionality also works for other applications or databases that flush in-memory data and pending I/O operations to the disk before a snapshot is made, creating transactionally-consistent VM replicas.
NAKIVO Backup & Replication allows for complete automation of VM replication jobs with the help of rule-based policies. You can set up replication policies based on VM size, name, location, tag, or any combination of these and other parameters. A policy-based job replicates all VMs that match the policy rules and scans your infrastructure periodically, adding new matching VMs to the replication scope. Thus, you can rest assured that your important VMs are protected at all times.
Flexible Retention Policy
With NAKIVO Backup & Replication, you can keep up to 30 recovery points for each VM replica. Being just a regular VM snapshot, each of the saved recovery points can be used to easily return the VM replica back to a previous state from a vCenter or ESXi server. The software relies on the Grandfather-Father-Son (GFS) rotation scheme, meaning that you can rotate recovery points on a daily, weekly, monthly, and yearly basis.
NAKIVO Backup & Replication can automatically verify all VMware VM replicas by powering them on (with networking turned off) and making screenshots of the booted OSs. The product sends you screenshots of the test-recovered VMs as proof that your VMware VM replicas are functional.
Replication From Backup
NAKIVO Backup & Replication is designed to add to the flexibility and simplicity of data protection tasks. Should your data protection policy require you to both back up and replicate specific business-critical VMware VMs, you can enable job chaining to replicate such VMs directly from their backups right after the initial backup jobs are complete.
Thin Disks for VM Replicas
With NAKIVO Backup & Replication, you can choose to create thin-provisioned disks for your VMware VM replicas, regardless of your source VMs’ type of disk. Thick-provisioned disks occupy all space assigned for a VM (including unused space) and, hence, are not efficient for space utilization. Thin disks, in contrast, consume only the space needed by the data (including the operating system and applications), helping you save a considerable amount of storage space.
NAKIVO Backup & Replication includes high-end DR functionality that allows for creation of comprehensive site recovery workflows. By combining various data protection actions into these workflows, you can automate the entire disaster recovery process, avoiding data loss and ensuring minimal downtime. In order to ensure your workflows work properly, you can perform scheduled, automated, non-disruptive testing, eliminating the risk of failure when actual disaster strikes. In addition, with the Site Recovery feature, you can perform planned failover, emergency failover, failback, and datacenter migration in a single click. This is a flexible feature suited for multiple purposes, improving the overall flexibility of the recovery process and saving you time.
Swap Data Omission
Serving as a “virtual memory” to improve performance of applications, swap files (Windows OS) and swap partitions (Linux OS) are included into each VMware VM replica you create. While swap files and partitions play an important role in the operation of applications and OSes in general, they can negatively impact the VMware replication process. Being subject to constant changes, swap files and partitions can automatically grow in size, meaning that significant amounts of unnecessary data are processed and stored each time you run VMware VM replication. NAKIVO Backup & Replication can automatically skip swap data in your VMware vSphere VMs in order to deliver higher replication speed and more economical storage space consumption.
LAN-Free Data Transfer
NAKIVO Backup & Replication is designed to ensure the fastest replication process possible. Aside from performing incremental replication, you can also have a LAN-free data transfer mode enabled. The LAN-free data transfer mode is based on two features working together – Hot Add and Direct SAN Access. By having NAKIVO Backup & Replication installed and running on a server with access to VM datastores, the solution can bypass the host’s TCP/IP stack, mounting (hot adding) VM snapshots and reading VM data directly from the VM datastores through the storage I/O stack. The Direct SAN Access transport mode allows the software to read VM data directly form a SAN storage device over Fiber Channel or ISCSI (provided that your VMware vSphere VMs are located on a Fiber Channel or an ISCSI SAN). The two features make it possible to offload your production network while data transfer rates are dramatically increased, resulting in faster replication.
SQL and Exchange Log Truncation
In case you are using Microsoft Exchange or Microsoft SQL Server, you should know that each change that is made to the database is also recorded in transaction logs, which can grow over time, fill up the disk, and crash the entire server eventually. NAKIVO Backup & Replication can truncate transaction log files of Microsoft Exchange and Microsoft SQL servers. After creating a successful vSphere replica, NAKIVO Backup & Replication can connect to your Exchange server, identify which transaction log files have already been saved in the database, and remove those log files. As a result, NAKIVO Backup & Replication creates regular, application-consistent replicas of your Exchange server and also removes the transaction log files to not let them consume all free disk space on the server.
Replication performance can be further improved through the use of an additional Transporter. A Transporter is the product component that performs all data protection and recovery tasks, such as ESXi VM replication, ESXi VM backup, ESXi VM recovery, ESXi VM encryption, and so on. To enable Network Acceleration, you only need to install another Transporter onsite or offsite, and turn the feature on. Each time a VMware replication job is executed, the additional Transporter can halve the load on your network and boost VM replication speed by up to 2X.
Encryption in Flight and at Rest
By installing an additional Transporter, you can gain another undeniable benefit. A pair of Transporters can perform VMware VM replication encryption to ensure your data unintelligible to unauthorized readers and impossible to decipher in the event of a cyber-attack. NAKIVO Backup & Replication safeguards your data both in flight (during the data transfer) and at rest (once the data reaches the repository), ensuring protection from access and malicious use by third parties at all levels.
The Multi-Tenancy feature included in NAKIVO Backup & Replication was designed to enable the delivery of Replication-as-a-Service and Disaster-Recovery-as-a-Service. You can create and manage up to 1,000 isolated tenants (customers) within a single instance of a product. In the multi-tenant mode, customers can access their VMware environments and perform all data protection tasks with no input on your part.
Advanced Bandwidth Throttling
Whether you perform VM replication during business hours or send replicas offsite over the Internet, saving network bandwidth is of the essence. NAKIVO Backup & Replication includes the Advanced Bandwidth Throttling feature to reduce the load on your production network with smarter bandwidth allocation. The feature allows you to control the use of your bandwidth by setting up global or per-job bandwidth throttling rules. For example, you can configure your VMware VM replication jobs to not exceed 50MB/s in bandwidth consumption during specific periods of time or set limits for particular jobs to have more granular control over the whole process. With NAKIVO Backup & Replication, you can choose to stick to one approach or combine the two of them for more advanced control.
Automated VM Failover
With Automated VM Failover, you can recover from disasters by running a single job. Once you have replicas of your business-critical machines, you can transfer your workloads to a secondary location in one click. To bring your DR automation to the next level, NAKIVO Backup & Replication allows you to create network mapping and re-IP rules. Since servers at the primary site and DR site differ in their configurations, you can set up a rule to switch VMware VM replicas from one network to another upon failover and assign new IPs to them, turning recovery activities into a smooth process.
Staged VM Replication (Seeding)
VMware VMs are often rather large, and thus initial VM replication can be a time-consuming process, though it can be easily solved by means of a staged VM replication. With that functionality in place, you can first transfer (i.e. seed) the initial VM replicas to removable media and then move the VM replicas to a new location. After that, you can create a new replication job, setting up the transferred VMs as the target, and perform only incremental replication.
You can easily integrate NAKIVO Backup & Replication with monitoring, automation, or orchestration solutions to reduce complexion and cut down costs associated with data protection management. Integration is available via a simple HTTPS API provided by the product. The API is included in an Integration Kit together with API documentation and code examples, which simplifies and speeds up the integration process for you.
In most cases, modern VM replication software solutions provide for automation of the replication process, allowing businesses to gain multiple benefits. Aside from being a strong time-saving technique that helps reduce manual effort, execution complexity, and time to recovery, automation also helps significantly reduce the risk of the human error that manual processes are prone to. NAKIVO Backup & Replication can help automate core data protection tasks, including VMware VM replication, with the Policy-Based Data Protection feature. The functionality can automatically add newly-created VMware VMs to existing replication jobs if such VMs match pre-defined criteria based on VM name, size, tag, location, etc.
Issues are often discovered when it’s too late – when the recovery procedure cannot be performed due to an invalid replica, resulting in downtime, which, in turn, can entail other severe consequences. Without validation in place, unusable VMware VM replicas can be classified as valid, turning the recovery process into a guessing game. NAKIVO Backup & Replication can validate usability and recoverability of VMware replicas upon completion of VMware VM replication jobs on demand or automatically. With Screenshot Verification, you can be sure that you always have the means for successful recovery.
Offload production environment
WIn some organizations, data protection strategies may require business-critical virtual machines to be backed up and replicated as often as possible to achieve tighter RTOs and RTOs. The combination of two processes is quite resource-intensive since both of them are snapshot-based operations. As a result, doubled load on the production environment can significantly slow down business applications. This can easily be avoided with NAKIVO Backup & Replication and its capability to perform replication from backup. The Replication from Backup feature can reduce snapshot overhead, thus, offloading the production environment, and freeing up valuable resources for other important operations.
Control bandwidth use
If multiple tasks are performed over the network concurrently, bandwidth can easily get congested. This results in a negative impact on performance of business solutions and applications. Similarly, VM replication jobs run during busy business hours consume too much network traffic, affecting the overall efficiency and timeliness of business operations. NAKIVO Backup & Replication features an Advanced Bandwidth Throttling functionality that was designed to purposefully decelerate network speed for chosen jobs or globally in order to allow for faster data exchange between other business-critical applications via the network when needed.
Schedule jobs to avoid overlaps
In large environments with hundreds or thousands of VMware VMs, finding free slots and scheduling replication jobs in such a way as to avoid overlaps can be a challenge. Moreover, while managing a big amount of virtual machines, it can be hard to track changes in the infrastructure and have all critical VM included within replication jobs. NAKIVO Backup & Replication improves job scheduling by providing the Calendar Dashboard, which displays all jobs and their predicted duration in a calendar view (much like meetings in a calendar application), in addition to allowing you to create new jobs or manage existing ones.
Protect your data from unauthorized access
With malicious attacks becoming more and more sophisticated, the importance of securing personal and customer data is undeniable. VM replication to offsite locations poses a risk that critical information may be intercepted in transit or accessed at the destination by a hacker. Replicas that travel over the Internet should be encrypted both before the first bit leaves the organization and after the replica reaches its destination. NAKIVO Backup & Replication uses the Advanced Encryption Standard with 256-bit encryption keys to protect VM replicas both in flight and at rest.
