Operation Overview
The Miramar real-time replication software engine operates with policy-based
automation rules used to define backup and recovery functions. Policies must be
carefully crafted so that they match your company security and archival rules.
When setting up a rule you can:
|
|
Filter out certain file types
|
|
Set up the method |
|
|
Include certain file types |
|
Set up the frequency |
|
|
Define the storage location |
|
Specify the data retention time
|
Once a policy-based automation rule is defined the Miramar real-time engine will
run automatically and silently and monitor all file activity on the machines
being protected by the Miramar client everywhere on your network. As soon as a
file been monitored by the replication engine is modified the changes can
automatically be sent:
- Locally to a drive attached to the host: (DAS: Direct Attached Storage)
- On a server attached to a LAN (NAS: Network Attached Storage)
- On a remote machine connected to the Internet (WAS: Web Attached Storage)
Miramar offers great performances since it replicates only the changed portion
of a file that has been modified and not the entire file. Consider for example
the case of a power point presentation consisting of a few existing slides, when
a user adds a new slide to the presentation then only the newly added slide will
be sent to the backup location. This efficient methodology allows files to be
replicated while saving network bandwidth. Software applications can save files
in different ways and since Miramar intercepts the file save activity there may
be slight variations on the burden of the network
Usually, greater data protection can be achieved by combining the following
methods:
- Replication
Using a Replication method a file is copied from a predefined source to one or
more destinations or target machines. The replication method is controlled by a
set of rules that determine the manner to handle all objects such as files and
directories. An object can be replicated immediately as it becomes created when
selecting the real-time option or backed up at a given point in time using a
schedule.
- File synchronization
Using a synchronization method a save to a file can be propagated through the
entire Miramar network of clients. This represents an efficient way to share a
file on a global basis.
Recovering data
The Miramar software creates automatically a restore command entry in the
recovery table each time a backup function is completed. This makes the process
to recover data back from a storage location easy and flawless.
