Backup used information mismatch

[arosiqueh]

We use PROXMOX 2.0 full updated and we've a cluster with 2 nodes. After having some problems with backups because we run out of space everything seems to work fine. However in one of the nodes in the backup storage the information summary it shows in the web interface says:

• Size: 57,09 GB
• Used: 10,90 GB
• Avail: 46,19 GB

But when loggin in the Promox node via SSH, and executing

ls -Rla /backup
​

there is nothing.

Can anyone tell me what's going on? Or how can I fix it?

Thanks in advance.
