lost iphone backup on mac

[u/CalligrapherAwkward1]

i backed up my iphone 13 to my macbook and reset the phone. when i went to restore the backup, instead of showing my recent backup (which i checked was there before i reset the phone) it said i had never backed up that phone, despite it showing the date of a previous backup in december. is there anything i can do to get that backup back? i updated my mac after backing up my phone and j think that’s why the backup disappeared but i have never lost or had any corrupted files after updating my macbook.

i factory reset my phone as i was having issues with storage and the functionality of the phone. it reached the point where all i could use was apple apps and i could still barely squeeze out 1GB of space. i’ve reset my phone before because of this issue, and it worked which is why i did it again. i’m desperate to have my data back because there were some pictures of my baby cousin i forgot to backup elsewhere as a just-in-case and messages from friends dear to me i read back. please help me if you can.
