    4.1 Remote Copy (D2D2R)

In order to avoid local data loss due to accidents such as natural disasters, remote data disaster recovery is also a common proposition for corporate data protection. Disaster recovery and backup integration supports remote data synchronization through remote replication technology to achieve remote data protection. This offsite data disaster recovery plan is also called "D2D2R".

The remote replication process consists of two parts: First, the production data is backed up locally, and the integration of disaster recovery and backup backs up the data in the production machine to the OFS volume of the local media server. Secondly, a remote replication link is created between the local and remote data centers. Based on the remote replication task, the backup data in the local OFS volume is synchronized to the remote disaster recovery and backup integrated media server to provide double protection for production data.

When the local production data or backup data is lost or damaged, the disaster recovery and backup integrated remote replication provides three flexible recovery methods to restore data synchronized to a different location to the local media server or production machine:

1)    Source-side operation to restore synchronized data to the source media server: Under the premise of the normal operation of the source-side console, users can restore data synchronized to a different place directly to the local media server. This process is also called "reverse synchronization".

2)    Operation on the source side and restoration of synchronized data to the client: In the VPN network environment, users can restore data synchronized to a different place to the production server on the source side based on the source management console.

3)    The destination operates and restores the synchronized data to the client: The disaster recovery and backup integration supports recovery of synchronized data to the destination client after obtaining the authorization at the destination, so as to achieve data emergency use. Authorization ensures the security of data recovery at the destination.

The remote replication feature is as follows:

l   Supports three remote replication modes, namely: one-to-one, one-to-many, and many-to-one.

l   The granularity of remote replication is a scheduled backup task. Supports synchronization of data generated by scheduled backup tasks of various application types, including files, emails, operating systems, databases, and virtualization platforms.

l   Supports block-level breakpoint continuous transmission. When the data synchronization is interrupted, the next time data synchronization is performed, the transmission can start from the breakpoint, improving the data synchronization efficiency.

l   Support internal and external network synchronization, you can use VPN or IP to map the network environment for remote replication.

The diagram of the three remote replication modes is as follows:

细粒度恢复 4.5 Fine-Grained Recovery

When disasters need to be recovered, the recovery time objective (RTO) is very important, and the traditional recovery scheme must restore the entire backup set, which makes the backup and recovery of massive data extremely difficult. In many cases, users only need to restore part of the data in the backup set, so the need for more fine-grained recovery becomes more urgent.
