Disaster Recovery
Click either Dell Security Management Server or Dell Security Management Server Virtual for specific backup requirements.
Dell Security Management Server requires:
- Nightly full backup with transactional logging enabled for the SQL server database.
- Weekly backup of the back-end application directory:
<Drive>:\Program Files\Dell.- This directory contains critical files necessary to connect to the database:
<Drive>:\Program Files\Dell\Enterprise Edition\Compatibility Server\conf\server_config.xml<Drive>:\Program Files\Dell\Enterprise Edition\Compatibility Server\conf\secretKeyStore
- This directory contains critical files necessary to connect to the database:
Dell Security Management Server Virtual automatically performs nightly backups. The backup location differs based on the version of Dell Security Management Server Virtual. The backups are located:
- For v9.11 and later:
/var/opt/dell/dsmsv/ftp/files/backup - For v9.10 and earlier:
/opt/dell/vsftpd/files/backups
These backups should be regularly pulled from the server and stored in a secure location.

High Availability
Dell Data Security management servers do not support an active/active method of redundancy. It is highly recommended to only have a single back-end server and adhere to the recommended Disaster Recovery planning. Due to the nature of how keys are stored on local endpoints, always-up availability is not required.
For organizations that require redundancy, Dell Data Security management servers support in-place hot-cold servers.
Dell Security Management Server SQL Clustering
Organizations using Dell Security Management Server can choose to use a SQL cluster. In this configuration, the Dell Security Management Server should be configured to use the SQL cluster IP or hostname.
Network Traffic
Endpoint traffic can be distributed between front-end servers and the back-end server. Optionally, multiple front-end servers can also be placed in the demilitarized zone traffic (DMZ) for activating endpoints and publishing policies to endpoints over the internet.
Below is an example of a large environment that may be leveraging all technologies that are mentioned above.
