Description

Performed backup, then restore to new location, got warning.

Warnings: [
Creating missing folder (redacted) for file C:\Users(redacted).exe,
Creating missing folder (redacted) for file C:\Users(redacted).exe ]

For restore operations, missing folders should not generate WARNINGS, especially if the restore is redirected to a new location instead of the original, as was my test case.

If you still want to log a missing folder, at most I would suggest they should be INFORMATIONAL, not WARNING.

Steps to reproduce

1. Do backup
2. Do restore to alternate location where sub-folders do not exist
3. Receive notice about errors/warnings "WARNING WHILE RUNNING (backupname)" Got "X" warnings
4. Check warnings... it's about missing folders. Duh. :)

• Actual result:
  Warning
• Expected result:
  No warning

This does seem weird. Would it ever matter if the destination folder is missing during a restore?

If it never does it should indeed be informational or not logged at all.

Usually this happens for a partial restore.

The reason it is a warning, is that the code is supposed to create the required folder structure first, and then restore the files. If a folder is missing, that is an indication that something unexpected has happened, hence the warning.

I think I recall that it can happen if you selectively restore a few files, as this excludes the folders from being restored. In this case the warnings should be "information" instead.

Extra background... I got the same warning appearing 3 times when selecting Restore files... while the file listing is loading. So before selecting what to restore or pressing the Continue button.

This issue is also triggered when you select a single file for backup, instead of whole directory:
Creating missing folder d:\a for file d:\a\b.test
Only backed up directories are created (?) and because there is now a file without a directory, it seems to trigger warning.
