rsnapshot.conf -减少冗长的参数没有达到预期的效果？

Question

TL;DR

是否有一些r快照的配置(请参阅下面的版本)，允许我将输出限制为由r快照本身生成的shell命令、错误和启动/完成通知，同时使rsync只在rsync日志文件中生成和记录所需的详细信息级别？或者更简洁地说，我是否可以使r快照输出的结果与r快照配置文件中的详细描述相匹配？

如果没有，是否有接受特性请求的r快照社区？

只有TL部分..。

经过一些故障排除后(见下文)，我的r快照和rsync的特定组合不再像过去几年那样工作了。具体来说，rsync的输出现在显示在r快照的控制台输出中，而不考虑rsnapshot.conf中的详细设置。我有一个新的FreeBSD 12.2安装

freebsd-version   
12.2-RELEASE-p10

rsync是作为pkg install rsnapshot的一部分安装的，rsync -V显示了

R快照的当前版本是：

my $VERSION = '1.4.4';

在发布此问题的原始形式并在其上睡觉之后，再加上前面提到的疑难解答，问题归结为:r快照从crontab运行，控制台输出中出现的不必要的rsync信息(尽管有冗长的1设置)似乎需要一个“包装器”脚本来抑制噪音，然后从r快照日志中组装正确的信息。这似乎是一个非常容易出错的过程，也可能是一个非常高的维护，因为升级打破了管道胶带性质的解决办法。

成本最低的路径似乎是放弃获取任何关于rsync传输有效性的统计信息。这使我能够维护监视rsync的成功/失败的可读性，并且在它确实失败时很容易地重新运行它。

显然，rsync (隐式-v设置？)显然发生了变化，如果有某种配置允许我在r快照输出(只有shell命令、错误和启动/完成通知)记录rsync日志文件中的rsync输出时，我很想知道这一点。

请记住，自2018年以来，r快照机制一直运行得很好，只需要重新安装FreeBSD 12.2就可以破坏它。以前的r快照制度是在升级的FreeBSD 12.1 (从10.x开始)上运行的(在相同的硬件上)。rsync和r快照最初是独立于FreeBSD 10.x端口构建的(按这个顺序)，并从那时起定期使用portmaster进行升级。

这一次(如前所述)，我用pkg安装了r快照，并让它安装rsync (以及它需要的其他东西)。

rsnapshot.conf仅在snapshot_root值和缩短的备份点列表中更改。

下面是我想要的监控电子邮件的输出(容易处理)(也就是说，没有所有的rsync噪声)：

上述电子邮件报告的Both来自同一个rsnapshot.conf文件。

这是我一直在做的疑难解答。测试4是我以前的最佳近似值。

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.

这是默认(已安装) /usr/local/etc/rsnapshot.conf文件，所有记录的更改都是针对该文件进行的。

Answer 1

看来你有rsync -v了。删除-v和rsync将变得更加安静。

您可以通过最初查看rsync_short_args和可能的rsync_long_args的值来检查这一点；下面是关于我的配置的示例：

rsync_short_args    -azHS
rsync_long_args     --delete --delete-excluded --numeric-ids --fake-super

如果省略这些值，则依赖于默认值保持不变。rsnapshot的changelog应该声明默认值是否已经更改，但是通过使用您自己的定义，您可以完全绕过这个问题。
