@thanhtantran you might just want to copy the mongo database directly. Using nodebb-backup is probably missing some of the newer db keys. Look at the docs for backup in the upgrades to get an idea as to how to do the mongodump
As of date is it the only option available? shared hosting still not possible?
Not unless the shared hosting provider gives you some command line access and will let you install nodejs, and run several npm commands. Plus they have to have MongoDB or Redis access for database. 😛 Most shared hosting providers don't have the software necessary for running nodebb, and they won't let you install it.
