Understanding replication
This chapter describes how to configure and manage the replication of protected data from an AppAssure 
source core to an AppAssure target core for disaster recovery. It includes the following sections:
•Understanding seed drives
•Understanding failover and failback in AppAssure
•Performance considerations for replicated data transfer
•Configuring replication
•Replicating to a self-managed target core
•Replicating to a...

Version 5.4.3 Revision B180 • Hosted and Cloud Replication. AppAssure MSP partners maintain multiple target cores in a data center 
or a public cloud. On each of these cores, the MSP partner lets one or more of their customers replicate 
recovery points from a source core on the customer’s site to the MSP’s target core for a fee.
Possible replication configurations include:
•Point to Point. Replicates a single protected machine from a single source core to a single target core....

Version 5.4.3 Revision B182 •Point to Multi-point. Replicates a protected machine from a single source core to more than one target 
core.

Version 5.4.3 Revision B183 •Multi-hop. Replicates a replicated protected machine from one target core to another target core, 
producing an additional failover or recovery option.

Understanding seed drives
Replication begins with seeding: the initial transfer of deduplicated base images and incremental snapshots of 
the protected machines, which can add up to hundreds or thousands of gigabytes of data. Initial replication can 
be seeded to the...

Version 5.4.3 Revision B184 •The second part is consuming, which occurs when a target core receives the transported drive and copies 
the replicated data to the repository. The target core then consumes the recovery points and uses them 
to form replicated agents (protected machines).
Because large amounts of data need to be copied to the portable storage device, an eSATA, USB 3.0, or other 
high-speed connection to the portable storage device is recommended.
Seeding is an...

connection.
• Number of protected machines. It is important to consider the number of machines protected per 
source core and how many you plan to replicate to the target. AppAssure lets you perform replication on 
a per-protected server basis, so you can choose to replicate certain servers. If all protected servers must 
be replicated, this...

Configuring replication
To replicate data using AppAssure, you must configure the source and target cores for replication. After you 
configure replication, you can then replicate protected machine data, monitor and manage replication, and 
perform recovery.
Performing replication in AppAssure involves performing the following operations:
• Set up a repository on the target core. For more information on adding a repository to the target core, 
see...
