Script for creating backup - Not working

Configuration
1

Hi
I create in location /home/homeassistant/.homeassistant/HA_backup_system.sh this script with privalages 0777 for owner homeassistant:

#!/bin/bash
sudo mount -t cifs -o username=USERNAME,password=PASSWORD //192.168.xx.xx/Backup/Home_Assistant /mnt/Backup
NOW=$(date +"%Y%m%d_%H%M");
sudo dd bs=2M if=/dev/sda of=/mnt/Backup/HA_backup_$NOW.img
sudo umount //192.168.xx.xx/Backup/Home_Assistant

then in shell command in Home assistant add:

backup: ‘echo [hass password] | /home/homeassistant/.homeassistant/HA_backup_system.sh >> /home/homeassistant/.homeassistant/Logs_scripts/backup/backup-date +%Y%m%d-%H%M.log’

Next in GUI HA i create script:
‘1552384920506’:
alias: HA_backup_system
sequence:
- data: {}
service: shell_command.backup

But when run this script in HA only create file date.log and nothing else…
Please help me. When run script /home/homeassistant/.homeassistant/HA_backup_system.sh from putty by user pi on raspberry all works ok.

Where did you get the script? I am not familiar with it.

3

I create this script. But it works from putty comanf line.

4

Please post the contents of the script, using the instructions at the top of this page to format it correctly.

corrected :slight_smile:

Is this a virtualenv Home assistant installation?

Does sudo require you to enter the user password?

Try redirecting stderr to the log too and see if there’s any new output;

backup: 'echo [hass password] | /home/homeassistant/.homeassistant/HA_backup_system.sh >> /home/homeassistant/.homeassistant/Logs_scripts/backup/backup-date +%Y%m%d-%H%M.log 2>&1'

Yes it is virtualenv on Hassbian.

When run write in log this:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

sudo: no tty present and no askpass program specified

So yeah it’s trying to run sudo and doesn’t know how to ask for a password (because it’s running without stdin), your best bet is to enable passwordless sudo for the user for that specific script. I don’t know how to do it off the top of my head but there’s documentation online on allowing passwordless sudo for a specific executable.

12

I also use other shell command:
update: ‘echo [hass password] | /home/homeassistant/.homeassistant/updateHA.sh >> /home/homeassistant/.homeassistant/Logs_scripts/update/update-date +%Y%m%d-%H%M.log’

with this sh:
#!/bin/bash

sudo hassbian-config upgrade homeassistant

and it works ok.

13

There is a way of configuring sudo to not ask for a password.

14

but please explaine me more…

i added to sudoers at the end this line:

hass ALL=(ALL) NOPASSWD:ALL

and also not working… Run script in HA but backup is not done.

17

is hass your username? I though the default user was homeassistant.

18

But in other shell command use Hass and works?

19

i found this thread and in this show that user name is hass

But when add user homeassistant to sudoers all works ok.
But i add this:
homeassistant ALL=(ALL) NOPASSWD:ALL

But how i can add only to have sudo to only one script ? Now has to all sudo access.
