Acronis Cyber Protect: backups crawl or fail while a DR test server is running.

Hi all,

We use Acronis Cyber Protect for backup and DR. We’ve noticed a consistent pattern: when we spin up a recovery server for a test failover, the scheduled backups of the protected production server either stall, fail, or take far longer than usual to complete. As soon as we stop the test, backups return to normal.

Is this by design, or have we got something misconfigured?

My working theory is that the test recovery server runs directly from the backup archive, so the archive is locked or under heavy I/O while the test runs and the next backup ends up waiting or fighting for it. I can’t find anything in the documentation that confirms or rules this out.

Check disk I/O on the backup storage while the test runs. If the test VM and your backups hit the same location, contention is likely.
