Request for Help: Preserving Important Website Memories and Database Backup

understand that FTP is the recommended backup method and I am currently downloading my website through FileZilla on a remote server. I know InfinityFree normally does not increase account limits, but I wanted to ask if it would be possible to temporarily increase my account’s inode or storage limit for a short period of time. My goal is only to create and preserve a complete backup of my website and database. Once I have secured the backup, I am willing to clean up files and reduce usage if necessary. I completely understand if this is not possible, but I wanted to ask respectfully because this website contains very important personal memories and I am trying to ensure that nothing is lost. Thank you for your time and consideration
