Is the job for CronTab correct?

Question

linux

Hello! Is the task for Crontab correctly compiled, which will run the /etc/backup.sh script as root every day?
I run crontab as root with the commandcrontab -e
0 0 * * * /bin/bash /etc/backup.sh >/dev/null 2>&1

Answer 1

Don't do tasks as root.
Remove the path to the shell from the command, configure the cron normally, for example, see the article www.codenet.ru/webmast/php/cron.php
If something does not work for you, then show the error from the logs.

Answer 2

basically correct.
But placing scripts in /etc is bad manners.
PS. In general, you just need to place a link to your script in /etc/cron.daily and it will be executed at 4:02 every day

Answer 3

I will add: a very vague concept is correct. For example, we can talk about the cron schedule.
It can be checked in at least two ways:
1. Get a grasp of the man to crontab
2. Use online services that can decrypt the cron format. For example:
- https://crontab.cronbox.ru
- https://crontab.guru
