rsync?

On a destination server, create a container with the same operating 
system/version.

Then copy it with rsync.

Please not that any files which are opened and in use, will most likely 
be corrupt and unusable. Most certainly this will be true for any 
database files, i.e. MySQL.



Also - if, on the source system, you have a filesystem with snapshotting 
functionality, you can snapshot, and copy the snapshot.
