What does the "r" in rsync stand for? —Preceding unsigned comment added by 188.155.163.235 ( talk) 10:57, 5 April 2010 (UTC)
Should this website ( http://www.rsync.net/) be referenced in anyway to this article? 76.81.25.214 08:40, 13 August 2007 (UTC)
in the second paragraph, it is not clear what "remote" and "local" mean in daemon mode. It could go either way. if it was "client" and "server" the "server" would be the machine where the "daemon" is. 68.70.67.226 ( talk) 18:53, 28 June 2011 (UTC)
The command line options that were just reverted were copied directly from http://www.linuxdevcenter.com/linux/cmd/cmd.csp?path=r/rsync - should someone keep an eye on that IP address to check they don't do the same thing again? -- Tango 18:42, 5 March 2006 (UTC)
The tutorial linked is "Last updated on November 20th, 1999", in other words ancient. There must exist a better one?
The External Link "Tutorial: Backing up files with rsync" http://www.linux.com/article.pl?sid=04/09/15/1931240 is redirected to a page with ad-only content. There is no tutorial there. Should it be removed?
(2007-04-18) Just to let you know. The purpose of selecting an article is both to point readers to the article and to highlight it to potential contributors. It will remain on the portal for a week or so. The previous selected article was WorldWideWeb. Gronky 11:32, 18 April 2007 (UTC)
(2007-08-28) Looking at http://samba.anu.edu.au/rsync/ and http://librsync.sourceforge.net/ suggests that rsync and librsync contain two different implementations of a similar algorithm, with rdiff and rdiff-backup (mentioned in the article) using the latter. If this is the case then should the article should distinguish more between the algorithm, its various implementations and software that uses it. —Preceding unsigned comment added by Edmundgreen ( talk • contribs) 14:48, August 28, 2007 (UTC)
"rsync is a software application for Unix systems" but "OS: Cross-platform", is that correct? —Preceding unsigned comment added by 87.239.63.225 ( talk) 14:45, 7 December 2007 (UTC)
What are the main differences between rsync and psync? Actually there isn't any article about psync yet.-- SiriusB ( talk) 13:02, 7 April 2009 (UTC)
Never heard of it, and it's not even made a Debian package, so I guess it's not used much? One thing the rsync article doesn't make very clear is that it's used a lot. JöG ( talk) 00:01, 9 January 2010 (UTC)
This text in the intro: An important feature of rsync not found in most similar programs/protocols is that the mirroring takes place with only one transmission in each direction. — what is it trying to say? I'm very familiar with using rsync and know approximately how it works, but I have no idea what that text is trying to say. At least (a) define "transmission" and (b) explain why it's so important. JöG ( talk) 00:10, 9 January 2010 (UTC)
can someone make it more readable, please? —Preceding unsigned comment added by 222.29.98.177 ( talk) 04:49, 14 April 2011 (UTC)
Despite claims to the contrary, it appears that Yintersync and Duplicati don't support MacOS. — Preceding unsigned comment added by 123.3.238.231 ( talk) 01:27, 3 July 2011 (UTC)
Due to the birthday paradox, the collision probability is not 2-160, but about 2-80. — Preceding unsigned comment added by 74.125.57.34 ( talk) 12:47, 11 May 2012 (UTC)
Collision probability of two hashes being the same is still 2-160. For example, if there was only 1 bit, the possibilities would be (0,0), (0,1), (1,0), (1,1), ergo 1/2 = 2-1 probability. You are correct in that because of the birthday paradox, you only need about 280 hashes before the collision is very probable. That still has no effect on the probability of a *single* collision. -- Petteri Aimonen ( talk) 16:25, 19 May 2012 (UTC)
I am attempting to link the following in the external links section:
Yes it is a blog, but it presents information that is relevant and currently important to most users of linux systems (system on which rsync runs). It shows how to use rsync in a manner that replicates Apple's Time Machine. This method isn't easy to find and is very helpful. 138.162.0.43 ( talk) 15:10, 7 September 2011 (UTC)
i have added an 'example' to the examples section with a reference citation... hopefully this will be a better way to provide this information. 138.162.0.42 ( talk) 16:15, 7 September 2011 (UTC)
Does Rsync go by file times to determine newness at all? And if so, how does it interpret them? People use Rsync even locally within filesystems and between external drives such as a USB dest. drive directly connected to the machine with the source drive from what I am able to gather. But if Rsync is doing all of this analyzing, and apparently not maintaining any databases (correct if wrong) would that not be more traffic between the drives than a straight copy? And if not... how can Rsync possibly guarantee the integrity of the files via a one time operation? It seems like if its going to be performing "rolling" checks over chunks of files then Rsync backup would require having Rsync rolling over the files so to speak nightly or as part of a sustained backup regime anyway... so to catch that one important change to a few bytes in some record in some binary file. Assuming the file system is not keeping track of that.
These questions seem to me what should be the meat of the article. I don't see any of these concerns being addressed. I don't have the answers, and can't seem to find the answers to easily myself. Thanks. Towards a more useful Wikipedia. -- 99.197.224.57 ( talk) 11:17, 7 November 2011 (UTC)
The top of the page lists the information "(Redirected from Rdiff-backup)" while there is an rdiff-backup entry in the table at the bottom of the page.
Clicking "rdiff-backup" in the table simply returns the rsync page again. Stuff happens.
Oh. And rdiff-backup is not simply rsync. It's an application. Having its own page would be nice.

They say it's for "remote sync" (e.g. at Digital Ocean), but I couldn't find one authoritative source. Yaroslav Nikitenko ( talk) 16:34, 13 February 2021 (UTC)
Hello fellow Wikipedians,
I have just modified one external link on Rsync. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.
An editor has reviewed this edit and fixed any errors that were found.

I propose to remove rclone from the table because:
- rclone doesn't use rsync,
- rclone is listed in the previous section.
Yaroslav Nikitenko ( talk) 16:38, 13 February 2021 (UTC)
I wrote much of the rclone article. As you say, rclone does not use rsync and doesn't belong there. When I started to write the stuff on rclone it was largely because the two were so confused. I wholly support your suggestion. Ed1964 ( talk) 16:20, 1 June 2021 (UTC)
Today it is explicitly mentioned in the table that rclone "Does not actually use rsync". This is better (though I don't remember what there was a year ago). However, it is still not based on rsync; other "Variations" are listed in the previous section (not added to the table). Yaroslav Nikitenko ( talk) 12:15, 3 July 2022 (UTC)
Should we add "/home/*" to the excluded list under the "Make a full backup of system root directory:" part? Usually, most Linux systems have /home mounted on a separate partition/drive? Sawyermade ( talk) 01:54, 22 June 2021 (UTC)
Software other than rsync can be added to "Variations" or to "rsync applications" sections. On articles like Comparison of file synchronization software I can see that that software is really established (though some programs are unsupported for about 12 years), and all tools have Wikipedia pages.
On the other hand, the list of rsync applications is narrower and the inclusion criteria may be more relaxed for the sake of completeness (even though this can be virtually impossible).
For example in 2021 the author added his program "tym" to the list of rsync applications. This program does not seem popular, and its last release was made in 2012.
I'm writing this because I created a new program using rsync myself (probably should give a link for concreteness); while I appreciate its features and quality, it is neither popular or known (at least at the moment). I added that to Arch Wiki, because such cases are explicitly allowed there; but for Wikipedia I'm not sure.
Is there an incentive to gather more Free Software rsync applications, or should they first satisfy some explicit criteria? Preferably objective ones; for example, Arch Wiki requires packages to be released in its user software repository AUR.
Yaroslav Nikitenko ( talk) 12:37, 3 July 2022 (UTC)
I decided to add YARsync to the current table, because there are other external tools (without Wikipedia pages) there. I think it would be easier to remove that if it is decided off-topic here (than to add), feel free to do that. Yaroslav Nikitenko ( talk) 13:10, 3 July 2022 (UTC)
