Within 30 days, you'll master:
- Backup for essential and enhanced cyber-resilience.
- Full server recovery and Hyper-V rapid recovery.
- Restoring files, mailbox items in Exchange, and other common data retrieval tasks after user accidents.
- Advanced tasks like restoring Hyper-V VMs, SQL databases
Here’s a typical plan to become cyber-resilient within 30 days. It’ll take about 2-4 hours per week over the next four weeks. After the free trial, you won’t just have backups; you’ll also have a well tested disaster recovery plan that you can put into action when disaster strikes.
Week 1
Backing up for essential cyber-resilience. Preparing for full system recovery, and setting up onsite, offsite and offline backups. Reviewing your goals and budget.
Week 2
Test recoveries: performing dry-runs of full server recovery (BMDR), and where appropriate, Hyper-V Rapid VM Recovery and Exchange Granular Restore.
Week 3
Backing up for enhanced cyber-resilience. Implementing multiple layers of protection that will complement each other – including cloud offsite backups, file replication for extensive version keeping, backing up workstation shares, and where appropriate, archival backups to tape.
Week 4
Putting together your Disaster Recovery Plan, with the assistance of our template. For large deployments, free trying Multisite Manager.
You too can join the other hundreds of thousands of organizations in 165 countries that we've helped become cyber-resilient.
Since 2002, BackupAssist has helped thousands of organizations become cyber-resilient. Let us help you too.

What do our clients say?
I appreciate the time that the BackupAssist Team takes to understand my situations and objectives. These days it is a breath of fresh air to speak with a live individual that calls you back and then does not rush, but patiently answers all of your questions clearly and knowledgeably. To top it off, their follow through on promised information is provided the same day instead of after you have forgotten about the conversation.

The BackupAssist Client Success team took the time to fully understand the disaster recovery needs of our target market and provided multiple solutions for consideration. The ability to choose between a perpetual license or a monthly subscription model was a definite plus. They continue to expand the capabilities of subscription offerings. A key feature, CryptoSafeGuard, protects our Clients’ backups from ransomware attacks. I was also surprised to have the CEO reach out to me directly for market feedback and feature requests we thought they might want to consider for future development.

As a public services organization supported by tax dollars, we are extremely cognizant and cautious in how our budget is allocated. We didn’t have an ‘enterprise-sized’ budget to spend on ransomware protection. However, we would be negligent if we didn’t invest in protection against the type of malicious software that could block access to our computers and data, and therefore our city services, until a sum of money is paid. And, that sum can be large – too large for an organization like ours.
This is exactly the position some of my colleagues have found themselves in – it was ugly – and it wasn’t anything I wanted even the remotest possibility of having to deal with here. BackupAssist’s CryptoSafeGuard will deliver the extra layer of protection organizations need at an affordable price.

About backupassist

Linus Chang
Founder of BackupAssist
Hello, my name is Linus Chang and I’m the creator of BackupAssist.
I first became aware of the need for backups when I worked at my university’s helpdesk. A PhD student come in with a broken floppy disk, asking for help. We tried some recovery techniques which failed… and then she broke down uncontrollably, seeing 3 years of her research and her mostly-complete thesis simply vanish.
Fast forward a few years, I saw the same problems in a business context. Why was it so difficult to back up a Windows Server? We were using batch scripts, and silent failures were a huge risk.
As a long time computer programmer (I started in 1985, aged 8, on the Apple //c), I decided to take action and write BackupAssist. That was in 2002. Fast forward to today, we’ve helped hundreds of thousands of I.T. administrators get reliable backups, and most importantly, get their data back when it matters the most. We’ve done the thinking and hard work, so you can follow a simple plan.
In the age of cyber crime and ransomware – let’s all stay cyber-resilient.

Wilson Nheu
CEO at BackupAssist
Hello, I’m Wilson Nheu and I’m the CEO at BackupAssist.
I spent nearly 10 years leading the R&D department at BackupAssist before taking on my current role. That first-hand insight into the nuts and bolts of our software, combined with a passion for market strategy have led me to where I am today.
There have been so many changes in the backup industry in the past few years, and I’m certain there will be even more in the years to come. We here at BackupAssist want to ensure that your business is cyber-resilient enough to keep up with the ever-evolving cyber-threat landscape, but at a cost that provides exceptional value for your money.
My goal is to ensure that BackupAssist evolves with the changing landscape while continuing to provide you with the products and services that meet your business needs.
