 ==== rsync (Linux !) ====
-''rsync'' is a convenient Linux command that can be used for mirroring a directory hierarchy to another location on the same computer (e.g. a removable disk) or a remote server. It can also be used on a Windows 10 computer where [[other:win10wsl|WSL + Ubuntu is installed]]! But it is probably easier to use the //mirroring// option of [[other:win10_syncback|SyncBack]].

+//Mirroring// means in the ''rsync'' case that we will **only copy new or changed files**. The first //copy// may take some time, but will be much faster afterwards, when only a few files have been created/changed and have to be copied. Or, if a copy is interrupted, the files already copied will not be copied a second time.

+Mirroring //no files// by mistake, to a place where there are files, with the ''%%--%%delete'' option, means that existing files or whole directory hierarchies will be deleted!
   * Be sure to understand the basic options, and use ''%%--%%dry-run'' (simulate what would be done) and ''-v'' (verbose) before performing an actual synchronization
