What remains to be done is to make the the rsync-no-vanished script accessible
to users. I created bug 10356 about including it in the tarball.

I should note that the issue with deletions being skipped has been fixed (the
file-has-vanished errors were changed into warnings).

The script support/rsync-no-vanished that will be in the next release.

Interesting to see how a simple request is actually a rather intricate little
problem in the bigger scheme of things. I'm very interested to see how this is
resolved (as I get back up warnings once in a while because of this).

By the way: Suggesting that removing warnings from the error log is silly.
Creating a script like this on more than 5 different machines gets old very
quickly.

(In reply to comment #18)
 What's also annoying is that a vanished file warning triggers:
 
 IO error encountered -- skipping file deletion
 
 which if I'm not mistaken stops *all* files from being deleted on the 
 receiving
 end, not just the ones that have vanished.

You're right that the IOERR_GENERAL flag (which corresponds to that message)
stops all destination files from being deleted.  But it is only supposed be set
when there is an error that might lead to the omission of existing source files
from the file list.  A run-of-the-mill vanished file should not set the flag. 
If you have a reproducible case in which it does, please file a separate bug.

+1 for --ignore-vanished. Filtering out the warnings when stdout and stderr are
redirected to different places isn't so trivial.

What's also annoying is that a vanished file warning triggers:

IO error encountered -- skipping file deletion

which if I'm not mistaken stops *all* files from being deleted on the receiving
end, not just the ones that have vanished.

Re: [Bug 3653] Reduce the need for the vanished files warning

[Henri Shustak]

 Doing nightly backups from cron is an *extremely* common use-case of rsync, 
 and
 telling each and every user of rsync that they should either A) write their 
 own
 shell script to filter and discard error messages, or B) play a constant game
 of whack-a-mole chasing down new --exclude options to add, is just silly.  It
 pushes work downstream that could be done upstream much more efficiently.  Why
 make each user write the same code over and over when the developer could 
 write
 it just once, and get it right?

You may want to take a look at LBackup : http://www.lbackup.org
Just one rsync based backup possibility. 

Note : The current version 0.9.8r5-alpha3 of LBackup, requires a wrapper script 
to be
put around rsync if you want to ignore the vanished files warning. : 
http://www.lbackup.org/developer/ignore_vanished_file_warnings

Any assistance to improve rsync / LBackup is warmly welcomed. Perhaps one 
option is 
a new option to suppress this file vanished warning is a possibility? I would 
be interested to have other peoples take on such an approach.

Me too.

Doing nightly backups from cron is an *extremely* common use-case of rsync, and
telling each and every user of rsync that they should either A) write their own
shell script to filter and discard error messages, or B) play a constant game
of whack-a-mole chasing down new --exclude options to add, is just silly.  It
pushes work downstream that could be done upstream much more efficiently.  Why
make each user write the same code over and over when the developer could write
it just once, and get it right?

Option A is bad because everyone gets to introduce differently-subtle bugs in
their script (wrong error code? accidentally ignoring too many error messages?
who knows. It's fragile.)

Option B is bad because I don't *want* to have a bunch of --exclude options for
my backup: disk and bandwidth are cheap, so I want my backup disk to be an
exact mirror.  That way, when the disk holding / dies, I can just drop the
backup in and boot it, being confident that everything is exactly the same.

This is a 'me too' for '--ignore-vanished-files' flag. Lots of legitimate cases
where files could vanish, so having the option to treat this as normal (i.e.
prevent rsync from producing this warning and ensure a zero exit value) should
be simple enough, and would prevent lots of people (me included) from needing
to use wrapper scripts, hacks and/or just give it to receiving the annoying
cron messages it causes :)

I ended up using the following script for snapback2 (which exits with the same
error codes as rsync if rsync fails:

# cat /etc/cron.daily/snapback2
#! /bin/sh
OUT=`/usr/bin/snapback2 21`
RET=$?
if [ $RET != 23 -a $RET != 0 -a $RET != 24 ]; then
echo $OUT
exit $RET
fi

this is a workaround, it would still be great to be able to tell rsync to
ignore vanished files.

Guys, I also find this warning annoying.
I get a pretty much daily email about it from my backup 'failing'.

/etc/cron.daily/snapback2:
rsync warning: some files vanished before they could be transferred (code 24)
at main.c(1515) [generator=3.0.2]

I am not even sure which files are vanishing.
I suspect the files are from a mail directory, where some spam messages are
moved after rsync builds the files list.

I vote for including the patch into rsync to make it more useful for this use
case.
