One of the possible restore options is "Omit deleted files".

The following example will explain the difference of a restore "with" or "without" this option selected.

FULL BACKUP

A directory "MYDIR" contains files "1.txt" and "2.txt"

A full backup of this directory is made.

CHANGES

After the full backup has finished, file "1.txt" is deleted and file "3.txt" is newly created.

An incremental backup of the direcotry is run now. This backup contains the new file "3.txt".

RESTORE

First note that a restore of the incremental session does not only restore "3.txt", the file that was backed up in that session, but will build up the complete restore chain up to the full backup session. This was already explained in this Support Tip: A restore is always restoring the situation of a specific point in time.

Now, when the restore is run "without" the "Omit deleted files" option selected, all the files backed up in the complete restore chain are being restored. In the above example that means: all 3 files.

However, when the "Omit deleted files" option is checked, only 2 files will get restored, as file "1.txt" had been deleted before the incremental session was run.

Because the incremental backup session was backing up the (modified) directory, it's possible to filter out the deleted file during the restore session. And this is exactly what happens with the "Omit deleted files" option checked.
