Error backing up VM. **detected chunk with wrong digest**

[Aldo Picariello]

Hi all,

Proxmox 7.3-6 VM, trying to backup to Proxmox Backup server 2.3-2.
Always getting error ** ERROR: backup write data failed: command error: write_data upload error: pipelined request failed: detected chunk with wrong digest **

VM is arround 300GB. Proxmox backup server directory is 1TB space available.

Any help, will be awsome!

Hi,
have you tried starting a Verification Job on the affected datastore? The error could indicate some sort of data corruption of already stored data blobs.
