Cron Job to snapshots

[Jinafuto]

Hello everyone,

I’m fairly new to Proxmox, so I'm not entirely sure if it operates like other Linux systems or has its own peculiarities.

I have already created a VM, but my issue is that when I create a cron job to take a snapshot, it doesn't seem to execute properly. However, the syslog shows the following:
"

Aug 20 12:00:01 sh3 CRON[312128]: pam_unix(cron:session): session opened for user root(uid=0) by (uid=0)
Aug 20 12:00:01 sh3 CRON[312131]: (root) CMD (/root/script/snapshotVM.sh)
Aug 20 12:00:01 sh3 CRON[312128]: pam_unix(cron:session): session closed for user root

"
The snapshotVM.sh script looks like this:
"

#!/bin/bash

DATE=$(date +"%d-%m-%y_%H-%M-%S")
qm snapshot 100 VM_$DATE --vmstate 1 --description "Snapshot VM successful"

"
The cron configuration is as follows:
"
0 12 * * * /root/script/snapshotVM.sh
"

#service cron status
● cron.service - Regular background program processing daemon

Aug 20 12:00:01 sh3 CRON[312128]: pam_unix(cron:session): session closed for user root
"
Note that when I run the script manually, it executes successfully.

Can anyone help me figure out why the snapshot isn't being created by the cron job? Thank you very much!

The PATH is probably different when running from cron. Try /usr/sbin/qm instead of just qm?
