[rsnapshot-discuss] rsync error 2

[Прокси]

Hello,

I recently upgraded Wheezy backup server to Jessie and since then I'm having
problem with rsnapshot. I'm getting:

/usr/bin/rsnapshot -V sync: ERROR: /usr/bin/rsync returned 2 while
processing ***@host

Running rsync commands from
rsnapshot -t daily
manually works, it's just that it doesn't work when called from
rsnapshot.

What could be the problem?

Thanks!

Have you customized ssh_args by any chance?

No, that line is commented. I do have something like this:

backup ***@ip:/ host rsync_long_args=--rsync-path='/usr/local/bin/rsync_wrapper.sh' --exclude-from=/etc/rsnapshot.d/host --delete-excluded

Some of those arguments could be in ssh_args if I'm not mistaken.

At a similar case I solved the problem by replacing:

$result = system(@cmd_stack);

with:

$result = system(join(' ', @cmd_stack));

Please try without the unnecessary single quotes.
Some versions of rsnapshot will run rsync directly without using a
shell to parse the command.

This might solve some problems, but it introduces new problems, like
you can't have directory names or arguments with spaces in them
(unless you take precautions to quote the spaces or something).

Removing single quotes worked. Thanks!

Could you please provide details of the complete error message from rsync
(triggering it via -v). rsync doesn't return just an exit code. And closes
without error description.

Sure.
