Agentless protection of Deep Security doesn't work after reverting Deep Security Virtual Appliance (DSVA) to an earlier snapshot

    • Updated:

Summary
The virtual machines (VM) protected by DSVA lose protection after reverting DSVA to an earlier snapshot.
Details
Public

Each VM protected by DSVA will have a virtual agent running within DSVA. Those virtual agents also store data such as configuration, events, and rules. These are stored on the DSVA virtual disk.
When DSVA is still alive, it also has a slow-path daemon communicating with the fast-path filter driver running on ESX. The latter is used for redirecting network traffic to DSVA for DPI checking.
If you revert a snapshot of DSVA, those files will be reverted to an old state, make all the VMs protected by this DSVA lose protection, network connection and other exceptions.
To sum it up, taking a snapshot of DSVA as backup is not recommended, and not supported as well.
