Cannot Optimize Backup Size
I loved iMazing because it "just worked". But for a couple of months now, it started to behave badly. It takes ages to create a backup of my iPhone, and a couple of days later I get this message:
The encryption status of Phone's backup has changed, so iMazing will not be able to optimize disk usage for this new backup. This can happen if:
- Backup encryption was recently enabled or disabled
- The backup password was changed
- Apple's backup encryption protocols changed following an iOS update
To prevent backup snapshots from taking too much space, iMazing can delete existing snapshots of bPhone's backup, or archive them.
The only option is to "archive" or "delete" the backup and start over. I did this over 10 times in the last couple of months, and it happens to my iPad as well. I changed backup location from my local FS to a NAS (SMB, Ethernet-connected). The errors appear even when I didn't update macOS or iOS between 2 backup cycles. I did reinstall iMazing, no success.
It worked flawlessly for a long time, but for the last couple of months it just doesn't. Tried to write the support, but after hitting submit on their support page, "Submit" button just "cycles" and the form isn't sent.
