Differential Backup vs. Incremental Backup
In earlier posts, we have covered how the incremental backup works. Now we will focus on how the differential backup works and compare it with the incremental one. Differential backup copies the differences in a VM made since a last full backup. This method is in between a full backup and a traditional incremental (not […]

Exchange Log Truncation in VM Backups
One of the tremendous benefits to application-aware backups is being able to perform application-aware tasks such as truncating log files. Application-aware backups are able to flush any application specific data out of memory and pending I/O operations to disk so that backups are consistent from an application standpoint. With NAKIVO Backup & Replication, we are […]

VM Backup vs. VM Replication
VM backup and replication are essential parts of a data protection plan. At the first look, they seem similar and interchangeable, and this is partly true. VM backup and replication pursue different goals, so you need to think of them both when setting up a data protection plan and understand the difference between them. VM […]

RPO and RTO: What Is the Difference and Why You Should Care?
The ultimate goal of data protection is clear: you want to be sure that you will not lose data if something goes wrong. However, it is quite costly to mirror all the changes in your virtual environment to a DR site. That is why you need to accept the idea that you will lose some […]

GFS Retention Policy Explained
At first, let’s recap what retention policy is and why we need it. Ideally, the goal of backup is the ability to recover data from any point back in time. The straightforward way to do that is to keep periodical backups, usually daily. However, even with space-saving techniques like forever-incremental backups, synthetic backups, data compression, […]

How Does Forever-Incremental Backup Work on VMs?
The simplest way of backing up a VM is doing the full backup. You just need to copy an entire virtual machine to a backup repository. This simplicity has its price: making the full backup takes a long time, loads production networks, and uses a significant amount of space. One of the ways to reduce […]

Benefits and Technologies of LAN-free Backup
During a backup, large amounts of data are transferred through the networks and can cause a slowdown of business-critical operations. Network administrators use various approaches to minimize the impact of backups on the daily operations. Among those are scheduling backups off the business hours and traffic-reducing techniques such as data compression and forever incremental backups. […]

VMware Backup Best Practices
Backups are a critical part of our VMware virtual infrastructure. These days with mission-critical 24 hour a day, 7 days a week, the always-on infrastructure behind many web-facing businesses, business continuity is essential. When thinking about backing up our VMware virtual environments, what are some best practices to make sure we are getting effective, efficient, […]

Backup Deduplication Explained
Large virtual infrastructures generate a vast amount of backup data that leads to the increase of spending on storage infrastructure: storage appliances themselves and their maintenance. So network administrators are looking for the ways to save storage space. One of the widely-used techniques is backup deduplication. A concept of deduplication is almost as old as […]

What is Application-Aware VM Backup?
When it comes to backups, there is a wide range of options that must be considered such as backup type, frequency, source, destination, and many others. Back in the early days of traditional backups, most backup solutions simply captured files on disk. However, in today’s modern backup technology world, most servers are application centric. Flat […]
