rsync_long_args quotes not preserved

What did you do?

I add the following argument to the configuration file: --rsync-path='sudo rsync' (I have also tried with double quotes). The documentation states: Quotes are permitted in rsync_long_args, eg --rsync-path="sudo /usr/bin/rsync".

What happened?

The resulting command (rsnapshot -t daily) is:

/usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded
--rsync-path=sudo rsync --rsh=/usr/bin/ssh
--link-dest=backup_destination
username@server_to_backup:path_to_backup \

this causes an error with rsync (sudo: unrecognized option '--server') since it executes

/usr/bin/ssh -l username server_to_backup sudo --server ???????? --delete-excluded --numeric-ids --link-dest backup_destination . path_to_backup

What did you expect to happen

The quotes should be preserved and the following resulting command:

/usr/bin/ssh -l username server_to_backup "sudo rsync" --server --sender ???????? --numeric-ids . path_to_backup

how do I ensure that they are preserved?

I have the same problem.

Trying to escape the offending space character:

rsync_long_args --rsync-path=sudo\ rsync

Which had the effect of making the rsnapshot -t alpha outputted command execute without error, but in actual use there is still the error:

Unexpected remote arg:...
