Backup doesn't work under cron

[kmfreas]

Hi there,

Love the script, it seems to work great when I run it normally. I'm having an issue with it not running in a cron job. I've checked many other related issues and didn't see anything directly related to my issue. I have to admit that I'm not the most familiar with cron jobs, so it could be something I just haven't done yet.

This is what I'm running from crontab -e, as user ubuntu (running it every minute temporarily until I get it working):
* * * * * /home/ubuntu/ec2-automate-backup.sh -r us-east-1 -s tag -t Backup,Values=true -k 7 -p -n -c /home/ubuntu/cron-primer.sh >> /home/ubuntu/backup.log

This is my cron-primer.sh. I added /usr/local/bin to the path as per this issue
#!/bin/bash -
# export PATH=/bin is required for cut, date, grep
# export PATH=/usr/bin is required for AWS Command Line Interface tools
export PATH=/bin:/usr/bin:/usr/local/bin

# AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY needed for AWS CLI tools
export AWS_ACCESS_KEY_ID=xxxxxx
export AWS_SECRET_ACCESS_KEY=xxxxx

# AWS_CONFIG_FILE required for AWS Command Line Interface tools (f.e. ".aws")
export AWS_CONFIG_FILE=/home/ubuntu/.aws/config

Thanks for looking!

I spent a damn load of time trying to resolve this issue.

The problem was in aws tool located in /usr/local/bin insted of /usr/bin, but somehow my script does not catch/execute cron-primer file, even if i specify it with -c /path/to/cron-primer.sh. So editing that was unsuccessfull.

In addition my command seems to redirect only STDOUT output to log file only and when error had place i saw an empty file that pissed me off.

As a final workaround-solution i just used sudo ln -s /usr/local/bin/aws /usr/bin/aws and everything went good.

I had the same issue - it does not seem to be reading the cron-primer file. Maybe there is a change that is breaking it, because I have used this script in the past in different situations without issue.

My quick workaround to get it working with Cron was to export the path export PATH=/usr/local/bin at the top of ec2-automate-backup.sh

ran into the same issue, had a lot of fun playing with crontab until I found aws was in ~/bin
long story short sudo ln -s /home/ubuntu/bin/aws /usr/bin/aws SOLVED it
