Proxmox VMs backup monitoring script

[MR_Andrew]

Hello!
I'm working on monitoring script for Zabbix. Purpose - get result of build-in Proxmox backup procedure.
Total Zabbix template will works with 2 scripts: discovery script that will find VM numbers and check if backup enabled; monitoring script that will do all other staff.
I want ask you to check my monitoring script. It's pretty much simple to understand. File attached.
Script works with 2 arguments: VM number and number of days to find backup files. Example:

./proxmox-vms-backup-status 100 7

I'm a little bit afraid about logic of script. I made tests of this script on 3 different proxmoxes with different versions. Now, after debugging and fixing issues that been found, seems like working correct. But I want to be sure that everything is fine before publishing to production.

Thanks a lot!
Kind regards, Andrew.

This is a good starting point, but the only real test is to restore your backup, e.g. real restore in another datacenter or unpack with vzdump, everything else is just a check if a file exists - or a test if the backup is correctly exported (not that it is correctly written).

Dear LnxBil, thanks for your reply!
I understand your idea. Unfortunately, I didn't found any way to check backup file consistence. Looks like Proxmox don't have such build-in procedure. It's pity.

"or a test if the backup is correctly exported" - what do you mean? Is it possible to check via bash?
Thanks!

Just extract the backup, if that works your backup has been correctly written:

If some are interested in Zabbix monitoring of PVE, I've also written some scripts. It also uses LLD to discover guests, storage, pools etc... It doesn't monitor backups, but can graph a lot of things. See
