Managing
StorageThis help page provides information to guide you through the tasks and procedures to manage replication with Navigator 2. It contains the following topics:
Navigator 2 provides access to multiple methods of backing up data. They are divided between two primary types: local and remote replication, as described below.
Local replication includes two methods of backing up information: ShadowImage and SnapShot. These methods create a copy of a volume (logical unit) in an array to another volume in the same array. You can create an actual copy of a volume by using ShadowImage and can create a virtual point-in-time copy of a volume by using SnapShot. ShadowImage and SnapShot treat the source volume, also called Primary Volume, and its copy, which is called the Secondary Volume, as a volume pair. For example, you can a copy by creating a pair. For detailed information and instructions, see the help page Local Replication.
ShadowImage and SnapShot are optional storage features and require licenses to be installed and/or enabled before they can be used. See the introduction help page and the licenses help page for more information about setting up optional storage features.
Remote replication includes two methods of backing up information: TrueCopy Remote Replication and TrueCopy Extended Distance. These methods allow you to create a copy of a volume (logical unit) in the array. TrueCopy remote replication allows the volumes to be synchronous at all times, while TrueCopy Extended Distance allows the volumes to be asynchronous. Both methods treat the source volume, also called Primary Volume, and its copy, which is called the Secondary Volume, as a volume pair. For example, you can a copy by creating a pair. For detailed information and instructions, see the help page Remote Replication.
TrueCopy remote replication and TrueCopy Extended Distance are optional storage features and require licenses to be installed and/or enabled before they can be used. See the introduction help page and the licenses help page for more information about setting up optional storage features.
Both local and remote replication have options which can be set via the items under Replication > Setup in the Arrays tree. Current options include:

Description |
|
Data Pools |
A data pool is a logical entity that can contain one or more logical units. A secondary SnapShot volume is a virtual volume that contains actual data from the primary volume and differential data stored in one or more data pools. |
|
SnapShot Logical Units |
A SnapShot Logical Unit is a virtual volume and is specified as the secondary volume of a SnapShot pair when you create a pair |
|
Remote Path |
Set the remote path to the system where the copy will occur. |
