I am looking for a backup solution to handle large documents well. I don't think that "back-up" software is what I am looking, but it is the best term I can see. We are not interested in recoverability or restoring the system as it is.
My wife is a photographer that takes about ~3GB/week worth of pictures. She would like to have to store all the pictures in an external storage. Yet, she would rather work on the pictures locally, when she uploads the pictures from camera or edits them.
We are looking for a tool that that treats the local drive like a cache rather than desired state to be restorable. So here are the requirements that we desire:
- You can work on your local data offline. We cannot just operate on the external storage directly.
- Any addition/modification changes to the local data will be propagated to the external storage the next time it is connected. Hopefully automatically.
- Any deletion on the local drive shouldn't be propagated to the external storage.
- Deletions on the storage drive would propagate to the local one, or at least once it is deleted it is never imported again from the local drive
- Not interested in state restoration. We don't care about how the storage was like two weeks ago. We'll never want to restore that stage.
Desires, but not requirements:
- Track file content rather than file names/paths. We would like to be able to change the directory hierarchy of the external storage without confusing the tool.
- Restoration of a file state. While we aren't interested in the state of the entire backup, it will be nice to see the changes each document went through.
In my simple view, this is what a document backup should look like; as opposed to system backup where I am always interested in restoring the system if it fails. Are there any software that uses this model? Any suggestions for my backup flow?
