Figure 7. Replication over the Internet
This solution provides granularity by allowing individual shares or iSCSI LUNs to be replicated from one ReadyDATA 5200 system to
another. This mirroring technology tracks blocks as they change and replicates incremental changes asynchronously from one
ReadyDATA 5200 system to another.
Sending only block-level changes from one system to the next means that only changed data needs to be moved and that the
performance requirements on both the source and destination systems are minimal.
Replication relationships can be configured as follows:
•
Constant replication
: Ideal for B2D, this configuration is driven by activity at the source storage system. Data is replicated to
the destination device constantly. Whenever new blocks are written on the source storage system they are immediately sent to
the destination source storage system. This is ideal in high-performance networks such as LAN environments or over fiber
connections between locations. This option is ideal for B2D solutions because it moves backup data as it is being created,
meaning that in the event off a disaster the most current data possible is in a secondary location.
•
Periodic replication
: Ideal for heavy production workloads, this configuration is driven by the clock. Data is replicated periodi-
cally every 15 minutes to 24 hours, based on how you configure your ReadyDATA 5200. This configuration collects changes
that occur over the selected time period and replicates them in line with the replication schedule. This option saves bandwidth
in environments where data is constantly being rewritten, such as virtualization or production database solutions.
Conc lusion
The ReadyDATA 5200 is a a cost-effective, easy-to-deploy, feature-rich repository for backup data. It works with any third-party
backup software to help you create a simple backup-to-disk data recovery solution. The ReadyDATA 5200 supports industry-
standard file-sharing protocols including iSCSI, CIFS, and NFS, and offers high-end features that greatly enhance your data
protection solution, including data deduplication, compression, cloud-managed site-to-site replication, high-efficiency data
snapshots, and instant expansion.
