| ''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]]. | ''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.

| | //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. |

| **Warning!** It's easy to lose files with ''rsync'' if you use the wrong syntax or options! Be sure to understand the basic options, and use ''%%--%%dry-run'' (simulate what would be done) and ''-v'' (verbose) before performing an actual synchronization | **Warning!** It is easy to lose files with ''rsync'' if you use the wrong syntax or options! |
