AMP Backup Failing: Minecraft Java Edition

[evsOri]

I am trying to schedule backups, but when I run the task, I get this output:

Failed - The process cannot access the file ‘C:\AMPDatastore\Instances\MinecraftJava01\Backups\20250328-011013-ae1edc0b68464729a10e3a769e0ce689.zip’ because it is being used by another process.

Not sure what could be accessing the file. It looks like AMP creates the backup and transfers some data into the ZIP folder, but then something accesses it and AMP stops the backup with this error.

Press the folder icon on the instance, then go to AMP_Logs to see what caused it

I am having the same issue. I checked the AMP_logs and it just shows the same error in the logs…

The devs are trying to narrow down the cause, in the meantime try stopping the MC server before taking the backup

I’ve set my server to go to sleep now a couple minutes before the automatic backup is taken and that seems to be working.
