ReadyNAS Replicate Software Manual
Simplified, Efficient Data Management
Managing efficient backup and restore tasks can be complex, even with the most
sophisticated tools. Coordination between the data source and backup target is required to
efficiently and consistently backup data or systems.
sophisticated tools. Coordination between the data source and backup target is required to
efficiently and consistently backup data or systems.
ReadyNAS Replicate automates and simplifies these complexities, creating point-in-time
backups, even if a backup job takes hours. It is as if the data on your ReadyNAS is taken
from a snapshot in time while the backup job executes. The data stored in each backup job is
cataloged and can be easily searched; even a single file within a job can be restored by date.

cataloged and can be easily searched; even a single file within a job can be restored by date.
Because backups are incremental, only data that has changed is backed up, however each
and every backup revision behaves as a full backup. By selecting a backup job and a restore
location, single points of data or an entire system are automatically restored without manual
copying or downloading.

Data is backed up from one ReadyNAS (called the source) to another ReadyNAS (called the
target). The target ReadyNAS contains most of the intelligence and manages the backup and
restore process. The source checks which blocks in a file have changed and only sends the
changed blocks, while the target catalogs the data from each backup occurrence in a manner
that makes it searchable with a fully indexed behaving like a full backup but at the cost of only
an incremental backup.

In addition, the target instructs the source to create a snapshot of the data to be backed up
and then instructs the source to release the snapshot when the backup is completed. Having
the intelligence in the target also allows data to be easily restored to any ReadyNAS device.

ReadyNAS Replicate can also be used to backup and restore unstructured file data across
your ReadyNAS devices, no matter where they are located. To back up structured data, such
as database files or virtual machine disk (LUN) on the ReadyNAS, these backups are "crash
consistent.” If applications, such as databases or virtual machines, do not quiesce and buffer
flushed, the data in the backup could appear as if the server was halted before all the data in
memory could be written to disk. However, most modern applications are designed to recover
from crash consistent data. Creating crash consistent backups has the advantage of putting
no load on the source host whether a database or virtual machine environment.
