Windows Backup error - Backup encountered a problem while backing up file C:\Users\xxxx\AppData\Local\Geckofx\DefaultProfile\places.sqlite-wal.


I cannot perform a full backup using Windows Backup to my 2 TB External HDD because it skips the file places.sqlite-wal. I have tried cleaning my browsing history then restarting still gives me the "some files were skipped" message. I am the administrator of my desktop and all the folders have read/write permission. Please help.

There is no need to backup sqlite-wal and sqlite-shm files.
That are temp files used by SQLite that only are present during the current session.
It is better to do the backup when Firefox is closed to make sure that all such temp files are removed. If those files are still there after Firefox has closed then something went wrong and other software may be causing their existence.

Question owner

Should I just change the backup to System Image only of C: and System Reserve as what Windows Backup states? Because even if I close Firefox it still shows the same error.
