Managing backup hosts
A backup host acts as a proxy client which hosts all the backup and restore operations for HBase clusters. In case of HBase plug-in for NetBackup, backup host performs all the backup and restore operations without any separate agent installed on the HBase cluster.
The backup host must be a Linux computer. NetBackup supports only RHEL and SUSE platforms as a backup host.
The backup host can be a NetBackup client or a media server or a master server. Veritas recommends that you have media server as a backup host.
Consider the following before adding a backup host:
For backup operations, you can add one or more backup hosts.
For restore operations, you can add only one backup host.
A master, media, or client can perform the role of a backup host.
HBase plug-in for NetBackup is deployed on all the backup hosts.
When using multiple backup host, make sure that all backup hosts are communicating with the media server.
You can add a backup host while configuring BigData policy using either the NetBackup Administration Console or Command Line Interface.
For more information on how to create a policy, see See Creating a BigData backup policy.
To add a backup host
- In the Backup Selections tab, click New and add the backup host in the following format:
Backup_Host=<hostname>
For more information on how to create a policy, See Creating a BigData backup policy.
Alternatively, you can also add a backup host using the following command:
For Windows:
bpplinclude PolicyName -add "Backup_Host=hostname"
For UNIX:
bpplinclude PolicyName -add 'Backup_Host=hostname'
For more information, See Using NetBackup Command Line Interface (CLI) to create a BigData policy for HBase clusters .
- As a best practice, add the entries of all the HMaster and Region servers to the
/etc/hostsfile on all the backup hosts. You must add the host name in FQDN format.OR
Add the appropriate DNS entries in the
/etc/resolve.conffile.
To remove a backup host
- In the Backup Selections tab, select the backup host that you want to remove.
- Right click the selected backup host and click Delete.
Alternatively, you can also remove a backup host using the following command:
For Windows:
bpplinclude PolicyName -delete "Backup_Host=hostname"
For UNIX:
bpplinclude PolicyName -delete 'Backup_Host=hostname'
