I confirm:

• [x] that I have searched for an existing bug report for this issue.
• [x] that I am using the latest available version of AMP.
• [x] that my operating system is up-to-date.

Symptoms

• What are you trying to do? Take a scheduled backup

• What are you expecting to happen? The backup to be taken successfully, without having to stop the server.

• What is actually happening? ('Nothing' is not an acceptable answer!) The backup task fails if a file is missing, sometimes games change files while running and it messes with the file index, or a user manually removes a file. If that happens after the index point, then the backup always fails outright.

Reproduction

Have an instance kick off a backup delete a file before it was archived notice failure
