Backup failures occur due to inadequate disk space for compressing and storing VM configuration files in the plugin-data folder, particularly when the specified drive lacks sufficient space. This situation is especially relevant when multiple drives (e.g., Drive P, Q, R, and S) are configured in the storage repository.

If the drive assigned for dumping backup files lacks the required space, the backup process will fail.

1. Check Available Disk Space:

Verify the available disk space on the drive where the plugin-data folder is situated.

2. Increase Disk Space:

If feasible, increase the disk space on the drive to accommodate the backup files.

3. Clean-up Unused Files:

Identify and remove any unnecessary or outdated files in the drive to free up space.

4. Reschedule Backup:

After ensuring sufficient disk space, reschedule the backup. Monitor the process to ensure successful completion without encountering previous space-related errors.

5. Contact Support:

If issues persist or new problems arise during the rescheduled backup, contact the support team. Provide detailed information about the environment, error messages, logs, and the steps taken for troubleshooting.

Note: Regularly monitor disk space across all configured drives to proactively prevent future instances of insufficient space issues. This preventive measure helps maintain a smooth backup process and avoids potential errors associated with insufficient disk space.
