Proxmox - Schedule twice a day, 7pm and 12pm

Another +1

We'd like to run mid-day incremental backups on our Proxmox VE servers, but the GUI scheduler doesn't allow scheduling backups multiple times per day (eg. 7pm & 12n).
Being able to fire-off the incremental backup job via a Powershell scheduled task would be a nice work-around.

Hi Andrew,

You can do that with a periodic schedule.
With a 12-hour interval, the backup would run at 12:00 AM and 12:00 PM.
That’s not exactly the required 7:00 PM, but it still gives you two backups per day.

Hi Andrew,

I split your request from the PowerShell topic.

We plan to introduce a "Backup Window" for periodic Proxmox job schedules in our summer release.
With this, it may be possible to configure a periodic 12-hour job that runs at 12:00 PM and 7:00 PM.

Best,
Fabian

Thanks Fabian,

Unfortunately, setting the 12-hour interval doesn't really work because we can't select when it triggers. I don't want ALL of our VMs backing up at exactly midnight & noon due to network congestion. It might work for incrementals, but that occasional full backup running on 20 VMs concurrently would cause problems. Setting the Proxmox agent to only allow 2 or 4 processes at a time might help alleviate the congestion but it's not something I want to test in my production environment (and my test environment doesn't have enough VMs & data to fully test the idea).

Would much rather be able to stagger them so Server A runs at midnight & noon, Server B runs at 1am & 1pm, Server C runs at 2am & 2pm, etc.
Still wouldn't allow for the scheduled noon/7pm type setting I'd prefer, but it would be a decent work-around.

Hi Andrew,

If the Backup Window for periodic Proxmox job schedules works similarly to vSphere jobs, your use case should be achievable by using different backup jobs with each one having a different "backup window".
Let’s revisit this once we have more information.
