Changing a replication repository to a primary repository

Changing a replication repository to a primary repository

If your primary repository becomes corrupt or otherwise unavailable, you can quickly change your replication repository to a primary repository to continue backup and recovery operations.

To change a replication repository to a primary repository:

1	In the My Repositories pane, right-click the replication repository, and click Remove.

 

IMPORTANT: Ensure that Delete all savepoints in this repository is not selected.

2

Click OK.

3	In the My Repositories pane, click Add.

4	Select the applicable repository type.

5	Complete the Add Repository dialog box, and click OK.

6	When vRanger detects that the repository being added contains savepoint data and displays the Warning: Existing Repository Found dialog box, click Import to reconfigure the repository as a primary repository.

Administering Data Domain and DD Boost

Data Domain system administration

This topic discusses the following subtopics:

•	Restricting export permissions to DD Boost

•	Modifying an interface group

•	Removing advanced load balancing and link failover configuration

•	Setting network timeouts

Restricting export permissions to DD Boost

By default, the DD Boost service is accessible to all backup server clients. By default, an asterisk (*) wildcard is used. To restrict access to a certain set of backup servers, remove the wildcard from the list and add individual clients to specify only those backup servers.

The list of backup-server clients can contain both FQDNs or short names. The FQDN of the backup host must be correctly configured for reverse lookup in DNS.

To delete all clients from the DD Boost clients list, enter:

# ddboost clients delete client-list

Optionally, to delete all clients previously added and reset the DD Boost clients list, enter:

# ddboost client reset

Clients can be added as both FQDNs and short names. To add clients to the DD Boost clients list, enter:

# ddboost clients add client-list [encryption-strength {medium | high} authentication-mode {one-way | two-way | anonymous}]

Example:

# ddboost clients add ddboost-dl.emc.com ddboost-dlddboost-dl.emc.com : Addedddboost-dl : Added

To view the DD Boost clients list, enter:

# ddboost clients show config

Notes:

•	Disabling DD Boost disables data access to all backup servers.

•	Administrators need to ensure that no backup jobs are running to the Data Domain system during these operations.

•	An FQDN, an IP address, or a DNS resolvable name of the client must be specified during the modification of the client access list.
