How do i backup all files listed in crontab
提问by Akki
I am trying to backup the crontab entries structure and files running under crontab.
我正在尝试备份在 crontab 下运行的 crontab 条目结构和文件。
But I am stuck with how do i search files in crontab -land copy the scripts running under it.
但是我对如何在其中搜索文件crontab -l并复制在其下运行的脚本感到困惑。
My possible ways
我可能的方法
I have listed
我已经列出
crontab -l > test.txt
cat test.txt
But how can I search the files after listing.
但是如何在列出后搜索文件。
My entries are like:
我的条目是这样的：
# daily pingback report
30 1 * * * php /var/opx/cron-script/daily-email-reports/pingback_report.php | curl --data-binary @- https://pxc.com/email/send
# --------------------------------------------------------------------------------------------------
# daily jobs 02+ hours
# --------------------------------------------------------------------------------------------------
# daily Failed Device Search
0 2 * * * /var/opx/cron-script/failed_device_search.sh
# daily Device Not Detected (we are not getting any of these, so commenting out)
# 5 2 * * * /var/opx/cron-script/device_not_detected.sh
# daily Failed App Search (we are not getting any of these, so commenting out)
# 10 2 * * * /var/opx/cron-script/failed_app_search.sh
# daily oss event report (uncomment when dev db issue is fixed)
10 3 * * * /var/opx/cron-script/event-analysis/daily-oss-event-report
# Copy tomcat logs from s1 and s2 , compress them and move to S3 storage
#30 21 * * * /var/opx/cron-script/log_backup.sh
I want to copy scripts running in these entries.
我想复制在这些条目中运行的脚本。

Try this:
尝试这个：
for part in $(sed 's/#.*//' test.txt | while read t1 t2 t3 t4 t5 main; do echo $main; done); do
echo $part
done | grep / | grep -v ://
For your example, this prints:
对于您的示例，这会打印：
/var/opx/cron-script/daily-email-reports/pingback_report.php
/var/opx/cron-script/failed_device_search.sh
/var/opx/cron-script/event-analysis/daily-oss-event-report
I'm not proud of it, but it is fairly portable shell, and seems to work for the cases you've given. You might need a smarter parser for more complex cases, or to handle more obscure words that may exist in your crontabs.
我并不为此感到自豪，但它是相当便携的外壳，并且似乎适用于您提供的案例。您可能需要更智能的解析器来处理更复杂的情况，或者处理 crontab 中可能存在的更晦涩的单词。

This is my script useful if any one want to backup cron's
如果有人想备份 cron，这是我的脚本很有用
#!/bin/bash
#This Script use for backup of crontab files and entries
#Modify as per your need
mkdir -p /mnt/cron_backups
for part in $(crontab -l | grep -v "clientmqueue" | sed 's/#.*//' | while read t1 t2 t3 t4 t5 main; do echo $main; done); do
echo $part
done | grep / | grep -v :// | while read -r row
do
scp $row /mnt/cron_backups/
crontab -l > /mnt/cron_backups/backup_cron.txt
tar -cvzf /mnt/cron_backups.tar.gz /mnt/cron_backups/
done
# grep -v is used for ignoring specific script with specific words or character
Thanks to John....
