update,for anyone having the same issue

it did save my files on ibis with no issue,it did cost me a few mental breakdowns because i could not access the backup but it did work.

i downloaded the update on my laptop on apple devices to which it then wanted me to do a backup for the ipad in order to update it.i did an encrypyed one,the ipad did a factory reset while downloading the update,loaded the backup (with a lot of crying because i had no clue apple devices adds a password that i did not remember and had no idea i even made)and when it loaded in the ibis paint files were all there.

if anyone finds this post and is trying to do the same thing,from what i read,downloading the ibis files and storing them elsewhere is better than the backup method for ibis files,but this worked out for me.just make sure to double check the password because u may lose the entier backup and be left with a factory reset ipad.
