rsnapshot.conf - 望む効果のない冗長なパラメータを減らしますか？

長い話を短く

rsyncが目的の詳細レベルを作成して記録している間に、rsnapshot自体によって生成されたシェルコマンド、エラー、および起動/終了通知に出力を制限できるrsnapshot（以下のバージョンを参照）のいくつかの設定はありますか？ただrsyncログファイルにありますか？それとももっと簡単に言えば、rsnapshotの出力をrsnapshot設定ファイルの詳細な説明と一致させることはできますか？

そうでない場合、機能要求を受け入れるRSnapshotコミュニティはありますか？

TL部分のみ...

いくつかのトラブルシューティング（以下を参照）の後、rsnapshotとrsyncの特定の組み合わせはもはや以前のようには機能しないようです。具体的には、rsyncの出力は、.rsyncの詳細設定に関係なく、rsnapshotのコンソール出力に表示されますrsnapshot.conf。 FreeBSD 12.2を新しくインストールしました。

freebsd-version   
12.2-RELEASE-p10

rsyncは一部としてインストールされて表示されますpkg install rsnapshot。rsync -V

RSnapshotの現在のバージョンは次のとおりです。

my $VERSION = '1.4.4';

この質問を元の形式で投稿し、寝る前に上記のトラブルシューティングを実行した後、問題は次のように解決されます。 rsnapshotはcrontabで実行され、rsyncの不要な情報がコンソール出力に表示されます（詳細な1設定にもかかわらず）。ノイズを抑えてからrsnapshotログから正しい情報を収集するには、「ラッパー」スクリプトが必要なようです。これはエラーが発生しやすいプロセスのように見え、アップグレードは回避策のダクトテープ特性を損なうため、メンテナンスコストが非常に高くなる可能性があります。

最も安価な方法は、rsync伝送の効率に関する統計を取得することを放棄するようです。これにより、rsyncの成功/失敗を読みやすく監視し、失敗した場合に簡単に再実行できます。

何かが変わったようです。 rsync（暗黙的な-v設定？）が疑われます。 rsyncのrsnapshot出力（シェルコマンド、エラー、および起動/終了通知のみ）から必要なものを取得できる設定はありますか？出力はログファイルに書き込まれ、これについて知りたいです。

RSnapshotメカニズムは2018年以来正常に機能し、FreeBSD 12.2を新しくインストールしなければこのメカニズムがハングアップすることに注意してください。以前のrsnapshotメカニズムは、アップグレードされたバージョンのFreeBSD 12.1（10.xで起動）（同じハードウェア）で実行されました。 rsyncとrsnapshotは元々FreeBSD 10.xポートとは別に（順番に）構築され、その後portmasterを介して定期的にアップグレードされました。

今回は（前述のように）pkgを使用してrsnapshotをインストールし、rsync（および必要な他のすべて）をインストールするようにしました。

rsnapshot.confは、値snapshot_rootと短縮されたバックアップポイントのリストのみを変更しました。

これは電子メールを監視するのに必要な出力です（処理が簡単です）（つまり、すべてのrsyncノイズはありません）。

上記の両方の電子メールレポートは、同じrsnapshot.confファイルから生成されます。

問題を解決するために私がしたことは次のとおりです。テスト4は、以前のテストに最も近いテストです。

1
rsnapshot -v alpha && /root/scripts/marklogs.sh --> using default rsnapshot.conf with 
 entries for rsync_short_args AND rsync_long_args  were actually elided from file (not left with # symbol)
 - normal screen output (start notification, shell commands, success notification)
 - rsnapshot log shows same as monitor output, no rsync log output

2 Explicitly add in default settings to the rsnapshot.conf file  
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha  && /root/scripts/marklogs.sh #--> rsnapshot.conf modifed as shown:
 rsync_short_args        -a
 rsync_long_args         --delete --numeric-ids --relative --delete-excluded
  - same as previous 

3 change rsync_long_args
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha  && /root/scripts/marklogs.sh #--> rsnapshot.conf modifed from default as shown:
 rsync_short_args        -a
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test
 - console shows expected output (start notification, shell commands, success confirmations)
 - rsnapshot log shows same as monitor output
 - rsync log shows building file list, files xferred, sent/received/total summary line for each backup point
 
4 change rsync_short args
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha && /root/scripts/marklogs.sh  #--> rsnapshot.conf modifed from default as shown:
 rsync_short_args        -rlt
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test
 - normal console output (start notification, shell commands, success notification)
 - rsnapshot log shows same as console
 - rsync log shows building file list, files xferred, sent/received/total summary line for each backup point

5 change rsync_short_arg to add -v
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha && /root/scripts/marklogs.sh  #--> rsnapshot.conf modifed from default as shown:
 rsync_short_args        -rltv
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test
 - console shows the unexpected (and undesired), given verbose set at 2, rsync output
 - rsnapshog log is polluted with rsync output, shows the start notification & shell commands before the noise, then some closing shell commands (touch /obopool/tester/alpha.0/; rm -f /var/run/rsnapshot.pid) then the completion notification
 - rsync log adds one line, "total size ..... speedup is .....", to logged info.
  
6 change loglevel to 1 to see effect on rsnapshot log
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha && /root/scripts/marklogs.sh  #--> rsnapshot.conf modifed from default as shown:
 loglevel                  1
 rsync_short_args        -rltv
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test
 - console shows same polluted output (rsnapshot shell commands with rsync data)
 - rsnapshot log received no ouput
 - rsync log shows same (correct) output as previous execution

7 change verbose to 1 (quiet) in rsnapshot.conf
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha && /root/scripts/marklogs.sh  #--> rsnapshot.conf modifed as shown:
 verbose                 1
 loglevel                  1
 rsync_short_args        -rltv
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test
 - console - no change to output from test 6 
 - rsnapshot log received no ouput (expected with loglevel 1)
 - rsync log shows expected output (same as previous)

8 set loglevel to 2 to verify effect on rsnapshot log
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha && /root/scripts/marklogs.sh  #--> rsnapshot.conf modifed as shown:
 verbose                 1
 loglevel                  2
 rsync_short_args        -rltv
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test
 - console - no change
 - rshapshot log shows only start and completion notices (no shell commands). One assumes errors would show up.
 - rsync log shows expected output

9 variation on 4: default verbose/log level - no -v on rsync_short_args, and add --stats to rsync long args
rm -rf  /obopool/tester/alpha* && rsnapshot -v alpha && /root/scripts/marklogs.sh  #--> rsnapshot.conf modifed from default as shown:
 rsync_short_args        -rlt
 rsync_long_args         --chmod D0770,F0660 --delete --relative --delete-excluded --partial --log-file=/var/log/rsync-test --stats
 - console has stats (rsync) information mixed in with correct output (start notification, shell commands, success confirmations)
 - rshapshot log has the same issues as console: stats output mixed in with  expected output (start notification, shell commands, success confirmations)
 - rsync log shows expected output -- files plus stats.
