Agentless backup in ESXi is very slow with the target location being NAS

Thread needs solution

Hi Team,

We are using Cyber protect 12.5 to backup multiple large VMs. We have Acronis agent virtual appliance deployed to each of the hypervisor.

Issue we are facing is backup job run by selected agent is very slow almost 1GB data takes one hour and eventually job will be frozen or stuck and eventually resulting in corrupted backup chain.

Job run by selected agents are very fast and can backup multiple TB of data within few hours.

We have verified the Synology NAS which is the backup location and could not find any issues. We are not using storage node in our deployment as well.

Hello Infra MSS,

Welcome to Acronis forums!

If this issue still persists, we recommend that you check the network configuration settings (e.g. network card) in hypervisor manager on any VM where the issue reproduces. If it is not that case, then this issue should be investigated by comparing agentless and agent-based backup operations logs.
