System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.93.4, branch: master, commit date: 2021-08-31 09:23, hash: b7205031ce
Worked: Never?

Short description of error
When using the 'Save Copy' function (from File menu or via op: wm.save_as_mainfile(copy=True)), packed images that have not been individually saved since their last change do not have those changes maintained in the saved copy.

Exact steps for others to reproduce the error
Create an image, set it to 'Packed', edit it in some way. Now use the 'Save Copy' function to create a copy of the blend file. Open the new copy and your edits to the packed file will be missing.
Workaround is to save all images before using the Save Copy function. However the current behavior is not intuitive and makes it easy to lose changes when creating backup copies of your working file.
There is also the case where you may want to have your current edits ONLY in the saved copy and not save them in the current mainfile, which currently is impossible to have happen.

Hi and thx for the report.

Blender currently only saves images separately from the .blend file (even packed images).
This is also true for regular saving (having unsaved edits on a packed image will also get lost).

This is definitely a workflow issue (not sure this can be classified as bug though), since 2.8 blender will prompt to save those changes when you leave the file (quit or open another file), but the core issue remains.
#45636 (Texture paint doesn't prompt user to save painted textures) is very much related, but since the prompt to save modified images does not trigger on Save Copy (and it probably should -- since you are effectively leaving that saved copy), I will leave this report separate for now. would kindly ask module devs for further input on this matter.
