I'm trying to come up with a method to store image files long term in a manner where they can be accessed but not changed (Write Once Read Many)
- Files will be ~1MB in size per, I don't expect to have more than 1000 or so over the lifetime. I may choose to burn a batch to CD/DVD for long term offline storage
- I'd like them in a format where I can read the file at any time but not modify or delete it
- new files can be added at any time in an automatic manner
I've looked at a few different options and I haven't found anything that works yet. The closest thing I found was using
chattr to set the immutable bit on ext4. The downside of that is only root can set the bit, even if I own the file. I'd rather not go down that route if possible.
