Periodic to Continuous Backup
Why Should You Consider Continuous Replication?
For many organizations, periodic backup has been the default way of replicating data for decades. Until relatively recently, creating a snapshot of your environment once daily was the default way of storing data for many organizations. Even today, periodic backup method may remain a cornerstone of the first phase of an organization’s hybrid cloud and DR strategy. But soon after setting up a snapshot-based replication solution, some organizations will bump into some of the limitations of periodic backup.
Typically, the process of creating and storing once-daily snapshots can lead to tech overhead and performance delays. As a result, your IT team may complain about storage shortages and employees throughout your organization may complain that they can’t access mission-critical applications with the high level of performance they’re accustomed to receiving. When this occurs, it may be time to consider a continuous replication solution instead.
A backup strategy that incorporates a continuous replication tool can address many of the performance, complexity, and granularity challenges associated with periodic backup. Here are three reasons many organizations should consider moving from a periodic backup solution to a continuous backup solution.
Reduce Risk of Data Loss: Since periodic backup often relies on once-daily replication, it may be impossible to recover data or files that were created after the last snapshot was taken. If a backup was completed at 7 AM and data is lost at 4 PM, a full day’s work may be lost.
Continuous replication creates a second-by-second record that allows you to return to a specific point in time prior to the deletion or theft of a file. Because continuous backup and replication is always ongoing in the background, the gap between when the last record was created and when the data was lost will never be longer than a second for many short-term storage strategies.
Reduce Impact of Downtime: According to research conducted by IDC, a single hour of downtime can cost as much as $250,000. The indirect cost could be much higher. Customers may decide that the outage is reason enough to take their business elsewhere. Others may vent about the outage on social media, which could cause prospects to remove your organization from their consideration set.
Balance Short and Long-Term Retention Needs: For many businesses, backup is not an all-or-nothing decision. While some applications may need the granularity of up-to-the-second storage, other data may need to be stored for seven years or longer but does not need to be replicated every day. Adding periodic backup for strategic, short-term storage can allow you to get the best of both worlds.
IPR Secure uses Zerto as its continuous backup replication partner. We often make the strategic recommendation to use Zerto’s IT Resilience platform to custom-fit a continuous backup strategy to build upon or replace a periodic backup strategy. When teams implement Zerto instead of periodic backup tools, they are able to meet aggressive RPOs and RTOs that would not be possible with periodic backup.
