Hard Drive is Full
Hello community, I'm having an issue with my iPhone backup, so my SSD is a 118GB SSD where I have my Windows OS and nothing else and I decided to back up my iPhone to my Windows PC with iTunes , it was a backup of 40gb, so since my Windows is like 20GB and the backup was like 40GB it was fine, but then when I wanted to restore my iPhone to the backup it said that the restore failed because some files couldn't be trasnfered, and I noticed everytime I try to backup from my iTunes backup the backup goes up in space, it takes up 80GB of space now and my hard drive is full, everytime I try to backup it goes up in space and thats why It fails, my SSD literally had 0GB left of space and the backup fails when its at no space left, is there anything I can do to fix this, I was thinking moving the backup to a different hard drive but I'm not sure if i'm going to be able to backup from iTunes if I move the backup.
Any help is appreciated, thanks!
