rsync - Command's extra options does not working on cron

[leonardokato]

Hi,
I'm using Rsync to backup PCs in my company but I have problem with extra options:

Code:

--exclude node_modules --log-file=/mnt/xxx/xxx/BackupLogs/backup_9/`date +%Y%m%d`.log

When I start job with this options manually from WebGui, it's running without problems BUT on cron I'm getting error:

Code:

/bin/sh: Syntax error: EOF in backquote substitution
/bin/sh: Syntax error: Error in command substitution

How to resolve this?

Have you tried double quotes around the entire command?

Have you tried double quotes around the entire command?

Hi,

Yes, still same error - here is email's subject from one PC:

Code:

Cron <root@DesktopNAS> PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/root/bin" /usr/bin/lockf -s -t 0 -k "/mnt/xxx/Backup/Klienci5" /usr/local/bin/rsync -r -t -z --exclude node_modules --log-file="/mnt/xxx/xxx/BackupLogs/backup_5/`date +

I don't see how your response corresponds with "double quotes around the entire command".

You don't need them for the paths with no spaces.

If you want me to show you how to fix it, you'll need to show me the whole line you are trying to put in cron.

Why is the command cut short? There is no closing back tick.

My advice is to package your rsync task as a shell script. A script is much easier to debug and get working smoothly. Then all you have to do is specify the script in your chron task, instead of an immensely long, complicated command. Like this:
