You can use the Wizard to create a Replication Set instead of using the
procedure below; to do so, right-click the ContinuousDataReplicator icon in the CommCell,
and select All Tasks, then select Replication Set Creation Wizard.
In the CommCell Browser, right-click the ContinuousDataReplicator icon of
the source machine, select All Tasks, then select Add Replication
Set.
In the
General tab, specify a Name for the Replication Set, and a Destination
Host that has CDR installed.
On Windows, in the
User Name
field, specify a Windows User Account who has the following privileges:
Is a member of the local Administrators group on the destination.
Has read/write permissions to the
product installation folders on the destination.
Has read/write permissions to the the replication logs
directory on the destination if it is not in the default location.
Has read/write permissions to the Job Results directory.
On Unix, in Data Replication Type area, select Preserve
Write Order option for database application. This enables the use of full data journaling
necessary to preserve the consistency of the database during
replication.
For Scheduled Replication on Unix, the following
options are selected by default to identify the backup data:
Use Journaling: This option enables the use of internal
journal to identify the backup data. Requires CDR driver; for supported
platforms see System
Requirements - ContinuousDataReplicator.
For Disk Library Replication, select this option to replicate
data between the MediaAgents installed in the source and destination
computers.
In the Pre/Post
Process tab, specify any commands to be run before a Recovery Point is created,
and/or after one has been created, and specify a User Account with permissions
to run the command(s) on the destination machine. For more information, see
Pre/Post Processes.
In the
Replication Options tab, make any appropriate selections. See the following
for more information:
Optionally, select the minimum file size to perform hash comparisons,
and the block size for hashing in the
Advanced tab.
Optionally, filter the content of any Replication Pairs that are created
for this Replication Set in the
Filters tab. For
more information about CDR Filters, see
Replication Filters. To exclude data from data
replication operations, do one of the following:
Click the Add button and, in the Enter Path window, type
the complete path (including drive letter) of the file/folder/directory
that you want to exclude from data replication. Repeat this step if you
want to add more files/folders/directories to the filter.
Click the Browse button and expand the file system of the client
computer. Click the file/folder/directory that you want to exclude from
data replication and then click Add. Repeat this step for each additional
entry.
To configure User Security for the Replication Set, after it has been
created, expand the ContinuousDataReplicator icon of the source machine,
right-click the Replication Set and select Properties, then select the
Security
tab. For more information, see User
Administration and Security.
Click OK to save your changes.
To specify that all Replication Pairs created for this Replication Set are
to use a Common Base Folder
(the same folder on the destination host to contain all destination paths) see
Edit a Replication Pair.
Create a Replication Set from a Replication Policy
To create
a Replication Set from a Replication Policy:
In the CommCell Browser, right-click the Agent icon of the source machine,
select All Tasks, then select Add Replication Set From Policy.
In the Select a Policy dialog box, select the replication policy
based on which you wish to create the replication set. The replication policies
created for the corresponding agent will be displayed. Click OK.
In the Enter Name dialog box, specify the name of the replication
set, and click OK.
The replication set will be created with the configurations available in
the selected replication policy.
Delete a Replication Set
When you delete a Replication Set, all of the following are deleted as well:
In the CommCell Browser, right-click a Replication Set icon, and select
All Tasks, then select Delete.
If Recovery Points were created for this
Replication Set and any of the snapshots were mounted, select the
Unmount and delete any manually-mounted snapshots before deleting
replication set option.
Click OK in the confirmation screen.
Start/Suspend/Resume/Abort Data Replication Activity for a Replication Pair
In the CommCell Browser, right-click a Replication Pair, and select
Start,
Start Full Resync,
Suspend, Resume, or Abort.
From the Replication Pair level, you cannot Suspend
a Replication Pair that is in the Replicating state; instead, do this
from the Replication Set level. See,
Suspend Data Replication Activity from the Replication Set for
step-by-step instructions.
To suspend
all data replication activity from the Replication Set level:
In the CommCell Browser, right-click a Replication Set in the source machine,
and select All Tasks, then select Suspend Data Transfer.
For Windows, if you Suspend Data Transfer for one Replication
set, you will be prompted with a list of Replication Set that have the same
destination.
If you click Yes all Replication Pairs on that source computer
which use the same destination computer will be placed in the Paused state,
even those that are in different Replication Sets.
For UNIX, data replication activities are suspended for all Replication Pairs in the
Replication Set.
Encryption settings made at the Replication Set level are for encryption
of data between the source machine and the destination machine.
Encryption must be enabled at the client level prior to configuring data
encryption for a Replication
Set residing on that client. See Configure
the Client for Data Encryption.
Click OK to save your settings and close the Replication Set Properties.
Add/Edit/Delete Filters for a Replication Set
Before You Begin
When Filtering is edited for a Replication Set, any existing and active Replication Pairs will be automatically aborted and restarted to effect the change. If the newly configured filtering excludes files or folders that had previously been replicated, these files and folders on the destination(s) will be handled according to your
Orphan Files settings.
To add/edit/delete a filter for a Replication Set:
In the CommCell Browser, right-click a Replication Set on the source machine, and select Properties.
In the Filters tab, specify the files and folders to filter from the content of any Replication Pairs that are created for this Replication Set. For more information, see Replication Filters.
To specify
a snap engine on Windows to the destination computer:
In the CommCell Browser, right-click the Replication Set on the source
computer and select Properties.
In the
Replication Options tab,
select one of the choices in the
Select
Snap Engine Type for Recovery Point Creation section.
For Windows,
VSS is the default selection; ONTAP can be used if available
on the destination computer where the Recovery Point will be created.
For
UNIX, Snap Engine Type is automatically detected by the File System
configured on the destination computer.
Click OK to save your changes.
On UNIX, CDR software
automatically recognizes the File Systems configured on the destination
computer and detects the appropriate snap engine. For more information on
supported snap engines, see Snapshot Engines - Support.
