src/backup.rs

   1 //! This module implements the proxmox backup chunked data storage
   2 //!
   3 //! A chunk is simply defined as binary blob. We store them inside a
   4 //! `ChunkStore`, addressed by the SHA256 digest of the binary
   5 //! blob. This technology is also known as content-addressable
   6 //! storage.
   7 //!
   8 //! We store larger files by splitting them into chunks. The resulting
   9 //! SHA256 digest list is stored as separate index file. The
  10 //! `DynamicIndex*` format is able to deal with dynamic chunk sizes,
  11 //! whereas the `FixedIndex*` format is an optimization to store a
  12 //! list of equal sized chunks.
