Configuring permissions for redirected restores
Certain restore procedures or environments require that you configure permissions to allow a client to restore a backup that another client performed. See the NetBackup Administrator's Guide, Volume I for complete details on redirected restores.
You must configure the primary server for redirected restores if you want to redirect the restore of ClientA to ClientB.
If you use a non-root service user account, specific access must be allowed for that user when you add files to the /usr/openv/netbackup/db/altnames directory. The service user account must have full access to these files through the ownership or group and the permissions. For example, if the service user is svcname and its group is srvgrp, the file can have permissions of 400. If the file owner is for a different user and group, the file permissions must allow access to the service user. For example, 777. Equivalent permission settings must be used in a Windows environment.
You do not need to configure redirected restores for the following configurations:
Restore databases in a SQL Server cluster to any of the nodes in the cluster
Restore databases in an availability group to any of the nodes in the availability group
Restore clustered databases in a multi-NIC environment across the private interface
Instead these environments require that you review the auto-discovered mappings for the hosts in your environment.
See Reviewing the auto-discovered mappings.
See Configuring mappings for restores of a distributed applications, clusters, or virtual machines .
To allow a specific client or host to perform a redirected restore
- On the primary server, create an
altnamesfile for each client or host that you want to have permissions to perform redirected restores.For example, to give
HostBpermissions to redirect a restore, create the following file:On Windows:
install_path\NetBackup\db\altnames\HostB
On UNIX:
/usr/openv/netbackup/db/altnames/HostB
- In the
altnamesfile, add the names of the hosts whose files the requesting client wants to restore.For example, assume that you want
HostBto have permissions to redirect restores fromHostA. Then addHostAto theHostBfile.
To give a SQL Server host the permissions to restore backups in a multi-NIC environment
- Create an
altnamesfile with the private name of the host, for exampleSQLHOST-NB.On Windows:
install_path\NetBackup\db\altnames\SQLHOST1-NB
On UNIX:
/usr/openv/netbackup/db/altnames/SQLHOST1-NB
- In the
altnamesfile, add the names of the hosts whose files the requesting client wants to restore.For example, assume that you want
SQLHOST1-NBto have permissions to redirect restores fromSQLHOST2-NB. Then addSQLHOST2-NBto theSQLHOST1-NBfile.
