These integrations orchestrate application-consistent snapshots on a desired schedule to ensure the OS and applications are in a consistent state before the snapshot is created. Veeam Availability Suite leverages storage snapshot operations to multiply the value of your investment virtualization and modern storage from: The best IT approach is to use storage snapshots and backups together to lower RPO and RTO down to minutes instead of hours and days - and in some cases weeks. The following table illustrates how storage snapshots and backups complement each other based on their respective strengths: Additionally, the number of storage snapshots you can create and save is limited in most scenarios.
Also, there are no safeguards to protect against an administrator deleting a snapshot on the primary storage, which may trigger the deletion on the secondary storage during the next replication.
Even replicating storage snapshots to a secondary storage system does not avoid problems if the data is corrupted or if there is an error on the storage system. However, storage snapshots alone are not the complete answer to bridging the Availability Gap.
#BACKUP STORAGE MEANING WINDOWS#
Storage snapshots shorten backup windows considerably, and they are especially useful when you’re doing many updates because it is easy to revert the system to a snapshot. Storage Snapshots and Backup: A Powerful Combination In addition, snapshots on their own do not have the means to check for corruption or restore capabilities. There is no way to restore if the source gets lost. This means that in case of a disaster or damage to the source data, the storage snapshot will be lost or inaccessible. Therefore, it depends entirely on the reliability of the source. The one of the differences between a storage snapshot and a backup is that the snapshot is stored at the same location as the original data. Because of that it, is very common to create lots of them to get RPOs down to minutes. Storage snapshots are created instantly, which means they are done within seconds. It is just a copy of the metadata that holds information about the data snapped that is used both for tracking purposes and for saving changes based on the pointer. A storage snapshot is similar: it is a point-in-time image-level view of data.Ī storage snapshot does not consume any space by default when it is created. Think of it as a photograph that captures a moment in time. In computer systems, a storage snapshot is the state of a system at a particular point in time. They minimize both the data traffic and the load required to create them compared to a backup. Snapshots are a common way to protect data and systems. When done correctly, backup operations provide long-term retention of backups for months and years with effective performance and space consumption. The rule states you should have at least three copies of your data, stored on two different types of media, with one copy stored outside your primary data center. Veeam recommends following the 3-2-1 Rule to protect your critical data and applications. With backup, you have an additional copy and multiple versions of a file, application, file system or other resource for use in the event of failure or loss of the original. What are Backups?īackup is a process that creates a consistent state of the application and operating system and then copies the data to a different location for safekeeping. This union creates the agility and responsiveness to deliver what Veeam calls Availability for the Always-On Enterprise. Let’s look at how backup and storage snapshot technologies come together in IT operations for a combined recovery time and point objectives (RTPO) of < 15 minutes for all applications and data.
This gives IT managers new levels of flexibility. With modern storage, virtualization and the cloud, backup, replication and recovery all work together. Companies need to be able to recover from the loss of data, applications, systems or location with minimal or zero downtime, and that is vastly different from backup solutions of yesterday. The new IT business objective is Availability. In today’s data center-powered world, we’ve come a long way from simple, legacy backup for data protection.
