I need to make a backup of my entire Users folder from within Windows, but I also really need to be able to use my computer normally. I'm planning to use Robocopy for this purpose, and want to clarify its behaviour when it comes to open files.
If I ran the following command:
robocopy SOURCE_PATH DESTINATION_PATH /e /z /copyall /r:30 /w:15 /mt:64 /v /eta
...how would Robocopy handle files from the source that I'm working on? Is there a possibility that the command will break, or will it simply skip the file after the specified amount of retries?
If it's just the latter, I'm planning to manually copy the modified files to the new directory at a later point and then compare the total size of the two User folders to be sure everything copied successfully.
In addition, what is the situation with using programs like Firefox while Robocopy is copying? What files, if any, does Firefox leave open while browsing, and will it be necessary to copy these over after the backup?
