No doubt, our reliance on large volumes of mission-critical data is ever-increasing. Also, our rising expectations for the data to remain intact, 24×7 available, 100% accessible, & reliably protected during a disaster event. Business units undergo mergers and acquisitions. At times, enterprises face unexpected disasters such as internet outages, database failover, natural disasters, etc. Such situations are almost inevitable within your business environment. But, this also warrants high availability and quick recovery of data.
With this in mind, businesses are turning to data replication software of their choice, like the VMware data protection. It’s enticing to use online data replication as a backup method. Many organizations even make it part of a “do-it-yourself” (DIY) strategy of disaster recovery solutions. Did you know that things can massively go wrong if certain considerations are not met? And these considerations might range from limitations of open-source data replication tools, application-specific agents, snapshot storage requirements to virtualization. Also, the cost & risks in syncing a large number of virtual workloads could be complex & expensive, if not managed properly. But, this might not be the case if you can demystify the common misconceptions related to data recovery replication solutions.
So, what’s the Right Approach for Data Recovery Replication?
To identify the right approach, here’s a small exercise of debunking the myth.
Myth: I am in charge of my Organization’s data backup and replication.
Truth: NOT all disaster recovery partners can optimize the compute capacity or address cross-region replication in one step. The key is to select the right software backup and replication solution that best fits your RPO & RTO objectives. After all, during catastrophic events, having a replica for ensuring data availability always makes sense for accomplishing disaster recovery. Hence, Replication comes into the picture.
What is Data Replication?
Unlike normal backup, backup & replication Synology creates copies of a database in more than one site/node or server. Since you can duplicate the data on an ongoing basis, the data is available to the users even during downtimes. So, the data stays consistently updated and synchronized with the source. The best part is that you can either set up a full replication or partial replication. In full data replication, you can copy the entire database. Whereas, in partial replication, you can replicate only frequently used data across the servers.
The article provides in-depth knowledge about how the Zmanda Recovery Manager (ZRM) provides near real-time data replication & backup for VMs. Zmanda has built this solution for customers to capitalize on full administrative access and control over VMware compute instances. Consequently, this makes the DR process much less painful & quick. In effect, this addresses customers’ business continuity and disaster recovery needs in addition to a global 24/7/365 support. Let’s dive deep into it.
Check out what makes Zmanda amazing in backup and replication
Here are the top six reasons to replicate your data to the cloud/ on-prem using Zmanda Recovery Manager (ZRM):
1. Delivering low RPOs –
ZRM’s approach to lowering RPOs to seconds makes the entire process of data recovery very easy. ZRM backup engine reads the data from the snapshot that appears in a specific moment (the exact time of the snapshot) to recover the MySQL database to a specific Recovery Point Objective. Since it continuously tracks the block-level changes of the VM data, this ensures real-time monitoring for consistent data backup. By employing robust data replication tools that include native code architectures, you can dramatically improve recovery point objectives (RPOs). Consequently, Zmanda leverages instant VMware backups to deliver 20 times faster storage snapshots to near-real-time RPO. Thanks to Zmanda’s vSphere backup and replication software that dramatically reduces the size of backup images.
2. Ransomware protection with air-gap –
Air-gapping works wonders with a simple formula. If the data cannot be accessed, it cannot get infected. Ransomware and cyberattacks are ruthless. Know that you are at the mercy of cybercriminals once you pay the ransom. Zmanda’s solution with the air-gapped technology is a robust encryption system. The software includes multiple layers of security to protect your business-critical backed-up data. ZRM smartly isolates the backed-up data and streams it through the encrypted tunnel from storage targets to resources for data replication. The replicated data is air-gapped by disconnecting the encrypted tunnel from the network. This makes the data isolated and cannot be accessed. This way your backed-up data is always protected & recovery-ready!
3. Protection for unlimited VMs –
Zmanda allows the users to backup and protects an unlimited number of virtual machines. For VMware data replication, ZRM employs vStorage APIs that directly communicate with the VMware ESXi host servers. This allows live migration of VMs from one server to another. As a result, it ensures continuous availability & reliable data protection for each of the hypervisors without data loss or downtime. The good news is that you just need one license to install on the server. This lets you protect an unlimited number of VMs on each ESXi Host (Hypervisor) individually.
4. File-level recovery (FLR) –
File-level restore plays an important role in recovering data. Especially, if you want to restore the previous version of an individual file that has been accidentally deleted. Database files are huge, and restoring the entire version of the virtual machine is cumbersome and time-taking. Zmanda’s special FLR feature creates two copies of specified, file-level content. Therefore, it’s convenient to access files within a restore point in time. Additionally, you can also compare the versions or overwrite the existing file to revert to its older version.
5. Instant recovery of snapshots –
In order to synchronize the data, ZRM creates snapshots for each point in time. Zmanda lets you create a logical copy that includes a MySQL binary log. Snapshots & binary logs save all individual database events and stores the last changed data (including full or incremental) backup. In effect, you can easily recover data from incremental backups thereby, achieving a more granular recovery point without any downtime.
6. Near-instantaneous hot backups for multiple platforms –
ZRM for MySQL supports snapshot capability for Linux Logical Volume Manager (LVM), Solaris ZFS, NetApp, VSS, Veritas, & VxFS Snapshots. In fact, ZRM performs backup by creating temporary snapshots while blocking the writes in less than a second time. For example, you can backup a mission-critical MySQL database, before any specific transaction error is made by the user. Besides, you can run instantaneous hot backups of live databases and rapid restores with minimal impact on the MySQL application. Thanks to the ZRM that integrates with EMC SnapView that facilitates rapid restores.
As your business contracts or expands, this calls for the virtualization of more workloads and applications. For enterprises, it’s crucial to minimize the data loss for customers without sacrificing business continuity and productivity. In this case, hunting for a Synology backup and replication solution tailored specifically to your business is daunting. Again, relying on the IT team for replication also doesn’t guarantee that your sensitive data is protected. This is because human errors are inevitable. In fact, this poses several additional concerns such as:
- Recognizing and setting the baselines of which backup or data replication software will work, and which not.
- Determining the right tools that are unique to backup and replicate data that offer storage, recovery, and backup.
- How you could narrow down the cost of each database backup and replication service for your business?
- Or, how would you calculate the acceptable recovery time frames for each service?
There’s no right or wrong answer to these questions. The key is to select the right backup and replication solution for your enterprise needs.
