ASR -replication issue

Question

I have an issue related to replication from HyperV to Azure. I did the configuration of the replication, and I have an issue related to the disk on the host. Every time I did the replication progress, the disk was full due to logs of ASR. How can I reduce that and fix this issue

@jihad majed Greetings!

While using Azure Site Recovery for replication from Hyper-V to Azure, it's common to encounter disk space issues related to log accumulation. The replication process generates logs that track changes, and these logs can grow, consuming disk space on the host where ASR is running. To manage these issues, you can follow suggestions below:

Azure Site Recovery maintains log files for several days by default. To mitigate the issue of excessive log growth, you can configure the log retention settings:

• Open the Azure Site Recovery console.
• Navigate to Recovery Plans and select the replication process.
• In the configuration settings, find the Log Retention Period and adjust the setting to a lower value (e.g., keep logs for only 1-2 days).

This will prevent the accumulation of unnecessary logs over time, thus saving disk space.

Increase the disk space available for the ASR logs by adding a new drive or increasing the size of the existing disk.

You can move the logs generated by ASR to a different location to free up disk space on the Hyper-V host. To do this, you can configure ASR to store the logs on a different disk or on a network share.

Clear or delete logs: Navigate to the log folder C:\ProgramData\Microsoft\AzureSiteRecovery\Logs. Delete any logs that are no longer needed, but be cautious to leave the most recent logs intact, especially if troubleshooting is required.
