[BUG] Backup failure during update for apps with large data directories causing app to fail to update

Describe the bug This bug occurs when an app's update process gets stuck trying to back up an unexpectedly massive data directory, triggering a system timeout of some sort. Because the backup fails mid-stream, the update aborts, leaving the application in a corrupted, semi-suspended state. The app repeatedly tries to restart and re-apply the update, trapping the app in an infinite loop of failing, crashing, and retrying.

To Reproduce Steps to reproduce the behavior: When attempting to update an application that contains a significant volume of data within its app-data directory, the automated backup process triggered prior to the update consistently fails.

Expected behavior Expect the app to fully backup and then upgrade

Server (please complete the following information):

• OS: Debian 13
• Tipi Version: v4.10.1

Additional context Logs below from error.log.history. My guess is its the default 5 minute timeout for events. The odd thing is I couldn't get plex to update or even start so I ended up having to uninstall and reinstall and then restore from an old backup.
