AGAIN....I reiterate: redundant magnetic media is great for backups.
You want to write ARCHIVES to the closest thing you can find to granite.
Right now, that is CD or DVD media.
Like it or not.
I need to erase my pictures because editing is a long run task (I am a stock photographer).
I need to have my picts on hand.
Because a Capture One user needs to update the settings of the processed picts.
Because I an currently living in a 15 m2 room and I have not space enough to store too much.
Because CD are too small for archiving the picts I could intend to archive.
Because DVD are not protected from scratches and I should need to backup the archives or archive them.
Because DVD are currently too under the Murphy law.
Less so than hard drives or tapes
Because I don't trust the plastic stuff where the DVD could be stored (getting old, plastic produce chlorine).
Paper or cardboard sleeves are now used, to attend to the chlorine...and as a space-saving device.
Because using as much databases as I could need to manage the backup, the archives and so others is a hassle.
The problem then, is not the technology, but the time and effort you would need to devote to doing it safely.
Because I use to live dangerously.
see below
Because archive on DVD is time and processor consuming.
Again, the problem is not the technology, but the time and effort required of you to do it.
With careful and under further considerations, unless I will change my mind, with all due respect to your background and your current experience, I actually forgo to archive (and I tell you this not using caps) and will keep my picts on a backup device.
The point of a backup is: To protect the files you are currently working on.
The point of an Archive is: To protect files you need to keep "forever".
You can always pull a copy of an archived file back into the working environment, completely unchanged. And, you don't need to Archive each and every copy of an image you make. You Archive only the original image. You Backup every revision and change you make. You may Choose to Archive the final, finished image...but that is a subjective choice.
Scratching a CD or DVD is less damaging than you might think. A scratch does not always destroy the data or make it unreadable.
Avoiding scratches, however, is a matter of procedure and handling.
Proper handling and storage will alleviate and reduce any possibility of scratching. You handle your DVD data storage as you would anything of value to your livelihood: with care and discretion.
Archive, Backup: The difference is obviously a semantic one, to some people.
Technically, there is a huge difference between Backup and Archive.
You are working with all this valuable data asset, but, what would happen if your building burns down???
With CD's or DVD's archived and kept offsite....say in a Safe Deposit box at a bank, or a Rental Storage Facility....you are merely inconvenienced....not devastated.
As usual: YMMV! What works for you, works for you. But, I look at what you wrote above, and see that you are still living dangerously. But, again, what works for you, works for you.
