Accordingly, your backup jobs finish much more quickly, as significantly less data needs to be copied. Thus, using the full synthetic mode for creating and storing backups drastically reduces the size of the backup jobs. With the three recovery point references and the changed data blocks recorded in the backup repository, the software can restore the full VM to the Sunday, Monday, or Tuesday state. The example below illustrates this process, showing how changes (or increments) made over three days in the source VM are then stored in the backup repository. Complementary features, such as data deduplication and compression, further reduce the data size, then update recovery point references to the deduplicated data blocks. Changes are saved to the backup repository as increments, and recovery points are created that reference these changes. Solutions using the full synthetic backup system take advantage of CBT or RCT technologies, which allow the software to quickly identify changed data blocks. A full backup is created only once, and all backup jobs thereafter are forever-incremental. With this approach, periodic full backups need not be performed. In contrast to the traditional backup types, such as full, incremental, or differential, the synthetic backup emerged quite recently. Full Synthetic Approach to Storing Backups You can download the free trial of NAKIVO Backup & Replication to try these features out for yourself and see the difference. Let’s review some of the features offered by modern VM backup solutions that can help you maximize your VM backup speed. To learn about 21 differences between legacy backup solutions and modern native VM backup solutions, download our free White Paper. In this regard, legacy backup solutions leave much to be desired, lagging far behind the ever-growing demands of virtualized environments. Modern VM backup solutions can provide you with the maximum possible VM backup speed in a given virtual environment. There is one major factor that affects backup speed, however: the agility of your backup software. cost, and cannot be easily improved without investment. These issues relate mostly to resource availability vs. The write speed of your target storage could also be limited. Your virtual environment may suffer from insufficient network bandwidth this could create bottlenecks between the source data storage, the backup software, and/or the destination data storage. There are many potential factors that could be slowing down your backup processes. As you scale out, boosting your VMware backup speed becomes a vital element in maintaining your virtual infrastructure’s resilience. The problem becomes all the more serious when your infrastructure comprises upwards of a thousand VMs. By Alex Mayer How to Increase VM Backup Speedīackup speed becomes a serious issue when your business operates 24/7 with hundreds of virtual machines up and running.
