76:262 Failed to replicate snapshots for subclient [...] using DDR.

This article describes the resolution for error message 76:262 Failed to replicate snapshots for subclient [...] using DDR.

Symptoms

Application backups failed with errro 76:262.

Causes

This error occurs when an agent level backup is run for an application that is already configured in an App Aware virtual agent subclient.

As an example, if a Virtual subclient is configured to back  up SQL via the App Aware feature, and then a backup is run for that client using the SQL iDA, it will fail with this error.

Resolution

In most cases, the backup for the client is part of a schedule policy and simply needs to be removed. If this backup was initiated manually, then confirm if the App Aware  configured backup is running and provides adequate data protection.
