Editing Rsync (section)

== Examples ==
A command line to mirror [[FreeBSD]] might look like:<ref>{{Cite web |title=How to Mirror FreeBSD (With rsync) |url=http://www.freebsd.org/doc/en/articles/hubs/mirror-howto.html |access-date=18 August 2014 |publisher=Freebsd.org}}</ref>

<syntaxhighlight lang="bash">
$ rsync -avz --delete ftp4.de.FreeBSD.org::FreeBSD/ /pub/FreeBSD/
</syntaxhighlight>

The [[Apache HTTP Server]] supports rsync only for updating mirrors.<ref>{{Cite web |title=How to become a mirror for the Apache Software Foundation |url=http://www.apache.org/info/how-to-mirror.html |url-status=live |archive-url=https://web.archive.org/web/20140821040343/http://www.apache.org/info/how-to-mirror.html |archive-date=21 August 2014 |access-date=18 August 2014 |publisher=Apache.org}}</ref>

<syntaxhighlight lang="bash">
$ rsync -avz --delete --safe-links rsync.apache.org::apache-dist /path/to/mirror
</syntaxhighlight>

The preferred (and simplest) way to mirror a [[PuTTY]] website to the current directory is to use rsync.<ref>{{Cite web |date=20 December 2007 |title=PuTTY Web Site Mirrors: Mirroring guidelines |url=http://www.chiark.greenend.org.uk/~sgtatham/putty/mirrors.html#guidelines |url-status=live |archive-url=https://web.archive.org/web/20140819090430/http://www.chiark.greenend.org.uk/~sgtatham/putty/mirrors.html#guidelines |archive-date=19 August 2014 |access-date=18 August 2014 |publisher=Chiark.greenend.org.uk}}</ref>

<syntaxhighlight lang="bash">
$ rsync -auH rsync://rsync.chiark.greenend.org.uk/ftp/users/sgtatham/putty-website-mirror/ .
</syntaxhighlight>

A way to mimic the capabilities of [[Time Machine (macOS)]];<ref>{{Cite web |title=Rsync set up to run like Time Machine |url=http://blog.interlinked.org/tutorials/rsync_time_machine.html |url-status=live |archive-url=https://web.archive.org/web/20071115224128/http://blog.interlinked.org/tutorials/rsync_time_machine.html |archive-date=15 November 2007 |access-date=18 August 2014 |publisher=Blog.interlinked.org}}</ref>

<syntaxhighlight lang="bash">
$ date=$(date "+%FT%H-%M-%S") # rsync interprets ":" as separator between host and port (i.e. host:port), so we cannot use %T or %H:%M:%S here, so we use %H-%M-%S
$ rsync -aP --link-dest=$HOME/Backups/current /path/to/important_files $HOME/Backups/back-$date
$ ln -nfs $HOME/Backups/back-$date $HOME/Backups/current
</syntaxhighlight>
Make a full backup of system root directory:<ref>{{Cite web |title=Full system backup with rsync |url=https://wiki.archlinux.org/index.php/Full_system_backup_with_rsync |url-status=live |archive-url=https://web.archive.org/web/20150211163817/https://wiki.archlinux.org/index.php/Full_System_Backup_with_rsync |archive-date=11 February 2015 |access-date=15 December 2014 |publisher=wiki.archlinux.org}}</ref>
<syntaxhighlight lang="bash">
$ rsync -avAXHS --progress --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} / /path/to/backup/folder 
</syntaxhighlight>

Delete all files and directories, within a directory, extremely fast:
<syntaxhighlight lang="bash">
# Make an empty directory somewhere, which is the first path, and the second path is the directory you want to empty.
$ rsync -a --delete /path/to/empty/dir /path/to/dir/to/empty
</syntaxhighlight>
