我已经使用了多年的rsnapshot，从来没有问题，但我无法弄清楚这一个。 版本是1.4.2。
我在rsnapshot.conf中有以下内容：
retain alpha 8 retain beta 7 retain gamma 8 retain delta 12 ..和crontab中的以下内容：
0 11,12,14,16,18,20 * * * /usr/bin/rsnapshot alpha 00 22 * * * /usr/bin/rsnapshot beta 30 2 * * 5 /usr/bin/rsnapshot gamma 00 6 1 * * /usr/bin/rsnapshot delta
beta和alpha作业完美运行：
root@host1:/Backup/rsnapshot_backups# ls -lt drwxr-xr-x+ 3 root root 4096 Oct 30 18:06 alpha.0 drwxr-xr-x+ 3 root root 4096 Oct 30 16:09 alpha.1 drwxr-xr-x+ 3 root root 4096 Oct 30 14:14 alpha.2 drwxr-xr-x+ 3 root root 4096 Oct 30 12:10 alpha.3 drwxr-xr-x+ 3 root root 4096 Oct 30 11:09 alpha.4 drwxr-xr-x+ 3 root root 4096 Oct 29 20:06 alpha.5 drwxr-xr-x+ 3 root root 4096 Oct 29 18:06 alpha.6 drwxr-xr-x+ 3 root root 4096 Oct 29 16:09 alpha.7 drwxr-xr-x+ 3 root root 4096 Oct 28 18:10 beta.0 drwxr-xr-x+ 3 root root 4096 Oct 27 18:06 beta.1 drwxr-xr-x+ 3 root root 4096 Oct 26 18:08 beta.2 drwxr-xr-x+ 3 root root 4096 Oct 25 18:09 beta.3 drwxr-xr-x+ 3 root root 4096 Oct 24 18:12 beta.4 drwxr-xr-x+ 3 root root 4096 Oct 23 18:16 beta.5 drwxr-xr-x+ 3 root root 4096 Oct 22 18:23 beta.6
然而伽马和三angular洲永远不会运行。 我究竟做错了什么？
从rsnapshot.log：
[2017-10-27T02:30:02] /usr/bin/rsnapshot gamma: started [2017-10-27T02:30:02] echo 2250 > /var/run/rsnapshot.pid [2017-10-27T02:30:02] /Backup/rsnapshot_backups/beta.6 not present (yet), nothing to copy [2017-10-27T02:30:02] rm -f /var/run/rsnapshot.pid [2017-10-27T02:30:02] /usr/bin/rsnapshot gamma: completed successfully
它抱怨无法findbeta.6，但我已经确认该目录存在。
