Here's my procedure:
1) Download PEF files to External Backup #1.
2) DNG Convert new PEF files to DNG files in new subfolder of current
year folder on internal drive.
3) synchronize PEF archive on External Backup #1 with External Backup
#2.
3) Sort, edit, whatever to new work on internal drive.
4) *every day* synchronize current year folder with backup copy on
External Backup #1, then synchronize to current year backup on
External Backup #2
At most, I can lose a day's current work, depending upon which drive
fails. Recovery, if a drive fails, is to put in a new drive and clone
back the data from the remaining two drives.
