Well, snapshots cannot be perceived as 100% reliable, as system memory writes immediately to disk when the VE unfreezes. If the system is not working hardly or content is static, then the snapshot is ok enough.


the system never freezes if you do snapshots with LVM (vzdump). I never had issues with Postgres, Mysql etc.

But if you run mysql or other database or any other system where data is particulary sensitive, you NEVER should rely on snapshot as it reverts to state of disk and NOT to the state of memory. Here the only way is to use application backup AND combine it with VE snapshot together.
