In order to facilitate backing up my photos I've adopted a bucket storage system. Basically I ingest all photos into an "ingested" folder, where I do the initial cutting of the bad photos, and some rating. I also rename in a way that gets me the photo date and camera model in the name.
The photos are then moved to my New Photos folder.
This folder is constantly synchronized to an external USB drive, a portable drive that then syncs to my office PC, and I do some more culling.
Eventually this folder reaches about 4 gb at which point I archive it to Dvd, rename it bucket0X (X being the next bucket number) and create a new New Photos and continue.
I'm looking at 2 possible problems:
1. I could open one of the files, pull it into photoshop, edit it, and accidentally save the edited version into the bucket folder. Unfortunatelly there's no way I'm familiar with to have Windows forbid adding files to a folder.
2. Even if I don't make the "save into a bucket" mistake, if I open a CR2 file and do some adjustments in Camera Raw, the XMP file wil be updated, and saved into the bucket folder.
Any thoughts on how to properly handle these problems?
