And here's another Syncback encomium, although I opted to pay for Syncback
Pro, which has the (for me, invaluable) facility to run the shadow copy
service. In other words, it will back up my Outlook data files even though
the files are currently open.
Of course, I didn't chance upon Syncback myself - I heeded the
recommendation of someone who knows better. Step forward Charles Norcutt,
sir!

Subject: Re: [OM] File losses
Understood that syncing may corrupt the backup but that is still my
preferred method since I prefer not to re-do some of the editing already
done and I have further protection in that I have more than one backup.
For backing up my C drive I use cloning and always keep 2 versions. For
things not on the C drive (such as my image files) I have for many years
used SyncBack SE <http://www.2brightsparks.com/syncback/sbse.html> and I
also have 2 copies done at different times. SyncBack provides different
forms of backup but I choose to sync old and new.
The way SyncBack works (when syncing) is to create a log file of the
files that will be copied from source to destination and those that will
be deleted from the destination since they are no longer on the source.
The items are color coded in the log such that they are easily
recognized. SyncBack first does the analysis and then displays the log
file. I examine the log file to see if it contains what I expect it to
contain. If you approve of the log file contents you tell it to go
ahead. I have been mildly surprised a few times by seeing something
queued for deletion that I didn't remember deleting (based mostly on
dates) but have never discovered an actual error. When I review the
related image folder I have always found that I did indeed deliberately
delete the now missing images. I've been using SyncBack for many years
and have never known it to make an error. Recommended.
Besides, I actually delete very few images. I only delete truly bad
images (poor focus, blown highlights, etc). Others that might possibly
have some redeeming qualities usually go into a "Discard" folder.
