SnapSHAt

This tool uses the existing Python standard library as of 3.11, no external dependencies are needed.

Note

When I was initially began writing this tool I was using SHA256 to compute file hashes but later found empirically that BLAKE2 was considerably faster, and since filesystems can easily exceed millions of files to hash it was a significant speedup to change the hashing algorithm. However, I still feel this pun encapsulates the essence of the tool and couldn't think of a better name.

Features

• Stores unique file contents in a "blob cache" where the content files are renamed after the hash of their contents (this is similar to how git stores files).
• Hardlinks files to these hashed blobs. The usefulness of this comes with subsequent snapshots, where presumably the majority of your filesystem is unchanged. Unchanged files will produce the same hash, and therefore can be hardlinked once again to the same blob which reuses the storage in the blob instead of creating a redundant copy o
