Cron

Here is an example crontab you might use with Zoneminder. These are put in /etc/crontab which is easier than managing individual user crontabs. Used in Devuan Jessie.

Example Crontab

#disable cron emails
MAILTO=""

#backup
00 5 * * 6 root mysqladmin -u zmuser --password=zmpass zm > /somewhere/zmdbbackup.sql

#reboot once a month
00 1 1 * * root /sbin/reboot

#monitor HDD health
00 1 * * 1 root /usr/sbin/smartctl -t short /dev/sda

30 1 * * 1 root /usr/sbin/smartctl -l selftest /dev/sda > /somewhere/HDD_HealthReport

35 1 * * 1 root cat /somewhere/HDD_HealthReport | mail -s "HD SMART TEST FOR ZM SERVER" email@address.com

#set different runstate for weekends
00 1 * * 6  www-data  /usr/bin/zmpkg.pl Weekend
00 23 * * 7  www-data  /usr/bin/zmpkg.pl Weekday

Tips

• The backup will give you a DB file but not save any of your images/videos. The DB can restore your configuration only. You might want to backup more frequently, if you dont want to lose a week worth of videos.
• Email must be configured to use mail -s (covered in wiki, look around).
• When changing run state via zmpkg.pl you must use www-data user. Combine this with the possible feature from SMS_Notifications.
• This example is intended for /etc/crontab. You do not specify user when you run a # crontab -e.
