Hi there,

I set a backup retention for all my VMs keep 3 lastest backup but I want to keep a VM with just 2 lastest backup. So I config in /etc/pve/vzdump.cron by add --prune-backups keep-last=2 but I have an error :

error during cfs-locked 'file-vzdump_cron' operation: value without key, but schema does not define a default key (500).

Can anyone help me? Thanks.
 
Hi,
I'd try removing what you added manually and rather configure the retention for the backup job via UI (Datacenter > Backup) or API. If that doesn't work, please post the output of pveversion -v and cat /etc/pve/vzdump.cron.

please share the output of cat /etc/pve/jobs.cfg and the exact error message you get. What do you get when you run pvesh get /cluster/backup?
 
Hi fiona,

here the Output:

I get a Promt with the following Error Massage:

I will post the exact Message as soon as i can get back to my Desk.

Thanks
 
Hmm, there is a mailto option but without any value which might be a problem. Or did you censor the value (if yes, please indicate so with xxx@xxx or similar next time)?

Please also share the output of cat /etc/vzdump.conf
