Yes, that is the one I meant. The scary-looking batch was the 3.4.0 security release: CVE-2024-12084 through CVE-2024-12088 and CVE-2024-12747. For the usual "rsync my tree to my own backup disk" case, I would not read that as a reason to panic or abandon rsync. Most of the sharp edges are in daemon mode, chroot/no-chroot setups, symlink handling, or talking to an untrusted peer. The practical takeaway is smaller: keep rsync updated, do not point backup jobs at arbitrary rsync servers, and remember that "plain files at the end" does not mean there is no parser/protocol code in the path. It is still a good boring tool; it just should not be granted magical immunity because the output is easy to inspect. -- TheLastSysop <thelastsysop@dev.null> "I survived the great rm -rf / rehearsal and all I got was this .signature."

But that’s what this entire thread was about, was it not? There was never the idea to use some public rsync service (is there even such a thing?) or anything like that.

I was separating two cases that tend to get conflated when people say "rsync is dangerous": * local copies, or rsync over ssh to a machine you control; * rsync daemon/module service, where the remote side is offering an export. For the first case, my worry list is mostly ordinary backup hygiene: use --dry- run when the command changed, be careful with --delete, and keep at least one versioned/offline copy so a bad source tree does not become tomorrow's only backup. Public rsync services do exist, mostly in the mirror world. A lot of distro and project mirrors have used rsync modules for pull mirroring. That is a rather different animal from "copy my home directory to my USB disk", though, and it is not the case I would optimize the advice around for a normal desktop/server backup. -- TheLastSysop <thelastsysop@dev.null> "I survived the great rm -rf / rehearsal and all I got was this .signature."

I sometimes used the '-delete' option to purge old files/paths. MOSTLY this worked perfectly. However in very very odd cases - esp if mounts dropped - it could erase a LOT of stuff. You can also engineer a 'reverse delete' - get rid of aged backups - also can be very useful, AND very dangerous. No all-around 'perfect' solution alas. Such is life. Never had time to look at dummy changelogs ... it was all automated/scheduled. POLICY was for people to save Real Stuff to the network shares. Sometimes they didn't - but we DID make it plain that stuff might not be preserved. That policy went back to Win95/Novell-Netware dayz. Giant heavy red and white box ...... :-) For Win workstations - there are a number of affordable 'image' apps to be had. We automated those. That'd at least fully restore individual boxes. Not ideal, but ... The REAL data though was SUPPOSED to be on net shares. That is what we'd guarentee. Worked. Save some spreadsheet to your LOCAL drive ... tuff titty.

Umm ... while rsync may occasionally add some NEW options, in my experience the OLD options keep working as expected. Did for at least a decade+ fer-sure. It's all VERY easy to script in half a dozen langs. Rsync is a spectacular utility. Never under-rate it. It's the ffmpeg of backups, and even more stable. NEVER seen a near equiv in the Winders world. Why IS that ??? For your server backups, DO leverage rsync. For user WinBoxes ... well ... there are some cheap-ish 'mirror' utilities that work OK. Automate them as much as possible. MY place ... POLICY was to put all the IMPORTANT SHIT on the SERVER shares - which were Linux. LOCAL, no backup guarenteed. Save that for "temporary" stuff. Didn't give 'em esp large local drives either, just to kinda push along The Paradigm.
