Hello I’ve have spend a lot of time the last couple of days trying to understand how Duplicacy works, so that I don’t mess up my backups by mistake. I have read the “Design and Information” how-to’s.
From what I understand the storage contains:
- Chunks: The actual files split into pieces.
- Snapshots: A snapshop represents an actual backup. The snapshot contains references to the chunks
- Config-file: The config-file is needed for duplicacy to read the storage.
At my computer I need only the storage info and encryption keys I used when I configured the storage to restore a snapshot. For example: If I delete the c:\Users\username.duplicay-web folder, I can just recreate the folder.
I can delete individual shapshot files manually from the storage if some of them contains missing chunks. I can then delete the unreferenced chunks with prune with the - exhaustive option (as long as there is no backup running).
Is all this correct?
Two further questions
- What happens if I delete the config file from the storage?
- What happens when I restore af snapshot with missing chunks? How much data will I lose? Is it only one file per chunk or could it be several files for a single chunk.
