For years now I have used Second Copy to both: (i) automatically backup my critical files to external storage devices (currently to a Drobo); and (ii) to synchronize key files between my computers across my network and laptops.
By and large it has worked well (perhaps some of its foibles will be the subject of a future post). But one thing it cannot do, and no other software that I’m aware of can, is backup Outlook’s PST files while Outlook is running. PST files are the files where Outlook stores emails, calendar data, contact info etc.
In my world, my PC is usually running 24/7 and so is Outlook.
For years I have searched, on and off and without success for software that can backup PST files while Outlook is running. Recently I came across Microsoft’s Outlook 2007/2003/2002 Add-in: Personal Folders Backup ("PFB")utility (download here).
While it cannot backup Outlook files while Outlook is running, it does the next best thing – it backs them up automatically when you exit Outlook. Since I exit Outlook at least a few times a week, my PST files are now backed up that often.
