Bisync does not copy the winner file to the loser site

nodtem66 · May 8, 2026, 3:31pm

What is the problem you are having with rclone?

Quick summary:

When using bisync with --conflict-resolve newer and --conflict-loser pathname and the files in both source and destination site are changed, rclone does not copy the winner file to the loser site.

Steps to replicate the problem:

Set up the local site rclone config create remote local
Create folders mkdir -p /content/src /content/dst
Create file.txt in /content/src

echo "hello" > ./src/file.txt

Resync rclone bisync /content/src remote:/content/dst --resync
Change /content/src/file.txt and then change /content/dst/file.txt

echo "src updated" > /content/src/file.txt
echo "dst updated" > /content/dst/file.txt

Bisync

rclone bisync /content/src remote:/content/dst --conflict-resolve newer --conflict-loser pathname --force

Expected behavior:
Both site should have file.txt and file.txt.conflict1

Actual behavior:
Could not find /content/src/file.txt. Found only /content/src/file.txt.conflict1

Notes:

Tested on both Windows and Linux
Only happened with --conflict-resolve newer --conflict-loser pathname. The problem solved when using --conflict-resolve newer --conflict-loser num

Run the command 'rclone version' and share the full output of the command.

rclone v1.74.0

os/version: ubuntu 22.04 (64 bit)
os/kernel: 6.6.113+ (x86_64)
os/type: linux
os/arch: amd64
go/version: go1.26.2
go/linking: static
go/tags: none

Which cloud storage system are you using? (eg Google Drive)

local

The command you were trying to run (eg `rclone copy /tmp remote:tmp`)

!rclone bisync /content/src remote:/content/dst --conflict-resolve newer --conflict-loser pathname

The rclone config contents with secrets removed.

#### What is the purpose of this change? Before this change, `--conflict-lose…r pathname` assumed `--conflict-resolve none`, following the legacy behavior prior to `v1.66`. This produced unexpected behavior when used with a different `--conflict-resolve` option. This change fixes the issue by ensuring that `--conflict-loser pathname` looks for the correct name on the side not being renamed, when only one side should be renamed. #### Was the change discussed in an issue or in the forum before? - https://forum.rclone.org/t/bisync-does-not-copy-the-winner-file-to-the-loser-site/53768 #### Checklist - [x] I have read the [contribution guidelines](https://github.com/rclone/rclone/blob/master/CONTRIBUTING.md#submitting-a-new-feature-or-bug-fix). - [x] I have added tests for all changes in this PR if appropriate. - [x] I have added documentation for the changes if appropriate. - [x] All commit messages are in [house style](https://github.com/rclone/rclone/blob/master/CONTRIBUTING.md#commit-messages). - [x] I'm done, this Pull Request is ready for review :-)
