What version of JBoss or WildFly?
And what you want to backup?
The configuration contains backups of the last used standalone/domain files.
The data or content will be more difficult, as you can't take a snapshot during runtime. There might be inconsistency as the backup will not take all files at the same time.
Back-up as in complete back-up of configuration/data files/applications altogether. Would it possible? manually i take back-up of everything but is there any automate way in JBoss?
No JBoss does not provide backup policies like this. This need to be done externally.
thanks for your suggestions,Fink!!Cheers!!
