1) What? Asynchronous/synchronous communication is a term used to describe 2 way communication over physical medium. Syslog-ng message relaying is one way and over tcp or udp.
2) Yes syslog-ng will send the unsent messages. You need the premium version for this feature.
the premium edition is only needed for disk based buffering. of course the OSE version also supports memory based queueing, and those get sent when the connection breaks.
3) You can use vpn tunnels or some other type of tunnel for this. Syslog-ng does not have any built-in transport encryption.
hmm.. it does support TLS. in my understanding it is a transport encryption.
4) If youre asking are messages forwarded to remote syslog-ng server as soon as theyre received, it can be configured this way yes. Or it can buffer them and send in bursts.
