Accelerated Data Copy (ADC) - ADC allows the system administrator to define a policy-based data migration, or a mass data migration to occur inter or intra Titan servers. Using BlueArc's Tiered Storage, ADC can move data between the various tiers of storage behind the server, in a non-intrusive fashion to the clients that connect to the server.
The data migration can be intra-server using the Fibre Channel network to migrate data between the tiers, and as the NDMP functions in Titan have their own, dedicated resources that are independent to the normal data access from clients, the data can be moved between tiers without affecting network clients, maintaining performance and removing any impact that this migration has on the Ethernet network.
In a inter-server data migration, one of Titan's Gigabit Ethernet interfaces can be used as a dedicated ADC or IDR interface, allowing data to be moved across servers and across the tiers of storage that each server supports. As the interface is dedicated to ADC or IDR, data migration is non-intrusive to the clients that connect to the server, again removing any impact to the network clients.
Incremental Data Replication (IDR) - IDR allows system administrators to setup a scheduled, incremental backup of a volume or a directory on the volume. Multiple schedules can be defined on a per server basis with support for pre and post scripting, enabling automated functions to occur prior and post the IDR schedule.
IDR uses snapshots as a basis for replication, maintaining the last snapshot as the reference point for the next replication to occur. Using snapshots as a means for replication also ensures files that would otherwise be skipped, as they are in use, are replicated and protected.
Using snapshots for replication also ensures that only changed files are replicated, drastically reducing the amount of replication traffic. Titan can support inter-Titan replication (local or remote) as well as intra-Titan replication, using BlueArc's unique Tiered Storage.
