NOTE:
Ensure that only one array is configured on each backup server.
•
The Create Remote virtual copy operation should use “Remote Virtual Copy” option.
•
This will ensure corresponding virtual copy is created on other site.
•
The remote site backup server information is required to specify as input for remote virtual
copy operation. For more information on Recovery Manager remote copy, see
for Recovery Manager” (page 89)
•
The corresponding virtual copy created on the remote site can be used for recovery operations
on the remote site.
Using Virtual Copy operation without Remote Copy, will only create a virtual copy on the local
site and that can be managed only by local site backup server. In case of a site disaster, the
production volume cannot be recovered on the remote site, as there would not be any virtual copy
on the remote site corresponding the local virtual copies.
Each backup server can only manage the SQL server and its Instance or databases that are currently
owned by the nodes on their respective sites.
NOTE:
Recovery Manager cross-site management is not supported.
For example. in
, the site A backup server can perform all operations on the
nodes on site A. Example: create virtual copy on an instance or a database which are currently
owned by the nodes on site A, that is node 1 and node 2. Site A backup server will not be able
to perform any operation on site B nodes such as node 3 and node 4 as they are connected to a
different array on site B. Similarly the same rules apply to site B backup server.
WARNING!
Any attempt to perform cross-site operation will result in a failure.
SQL server and its Instance or databases owned by one site can failover to other site. In such a
scenario, the other site should be used for subsequent virtual copy operations.
Recovery operation can only be performed on a site using the virtual copy created on that site. If,
there is a failover of the SQL server after virtual copy creation, to use the virtual copy for recovery,
the SQL server must fail back or must be moved back to the earlier node where virtual copy was
created.
Cluster Virtual Network Name (VNN) must be used for registering SQL server to Recovery Manager.
Cluster VNN must be used when a mount needs to be done to an owning node. The command is
automatically directed to the owning node. However, if the current owning node has crossed over
to the other site (remote site) due to failover or planned movement, then the mount operation will
fail. In such a scenario, the other backup server must be used for the mount operation.
Recovery Manager supports Synchronous remote copy configurations.
In Synchronous remote copy, Recovery Manager creates virtual copy on the local site first and
then it creates virtual copy on remote site. Therefore, virtual copy management such as mount,
recovery, and backup can be performed on both the sites.
