We are trying to backup several read-only volumes using proxmox-backup-client and have encountered the following error. We suspect the issue might be related to the application's inability to save the file to the backup path. While we have come across posts mentioning this error, those seem to associate it with /tmp not being accessible. However, we have verified that /tmp is indeed accessible in our case. Despite the error, the backups do eventually complete, although the process is slow.
Runtime output as follows
