Backup is for disaster recovery and it should be able to cover the disaster and not add a burden.
In Linux "tar" is a good old tool which does a pretty awesome job to backup or copy files.

Some basic commands below to move or copy files and pipe to "xargs" command.
By typing: ls *.log this will filter the output for files with ".log" extension.
     ls *.log | mv $(xargs) /path/another_folder

Move Recursively:
