Install the Virtual Server Agent on a Windows or Linux instance in the OpenStack environment.
Only instances that have the VSA installed can act as VSA proxies to perform backups and restores.
At least one proxy is needed for each region. You can deploy additional VSA proxies as needed for load balancing.
The following operating systems are supported for VSA proxies:
-
Microsoft Windows Server 2016
-
Microsoft Windows Server 2012 R2
-
CentOS 7
-
RHEL 7.2, 7.3, 7.4, 7.5
Note
Linux proxies must have the psmisc and lvm2 packages installed.
The Virtual Server Agent should be installed on instances that meet the following requirements:
-
Minimum of 100 GB disk space recommended
-
Minimum of 4 GB RAM required beyond the requirements of the operating system and running applications
For Windows proxies, VirtIO version 62.73.104.11800 is supported as a driver for OpenStack backup and restore operations.
For Linux proxies, disable lvmetad.
