ファイルを同期できません。

2つのサーバー（server1とserver2）間でファイルを同期しようとしています。ユーザーを作成し、そのユーザーに/ var / wwwのRWXに対する権限を付与した後、次の一貫したプロファイルを追加しました。

root=//var/www/html/
root=ssh://user@server2//var/www/html/environments/simreg/


log = true

ignore=Path cache
ignore=Path vendor
ignore=Path logs

fastcheck=true
prefer=newer
silent=false
times=true
owner=true
server = true
confirmmerge = true

backupdir = /var/www/html/environments/backup
ui = text

ただし、一貫性を維持しようとすると、バックアップは作成されません。デバッグがうまくいかず、私が間違っていることに気づいていませんでした。

上記はデバッグ印刷です。ただし、ファイルは両方のサーバーにあります。
