Good time of day. I have several questions about data deduplication on btrfs. Sorry if i ask stupid questions or waste you time %)
What about implementation of offline data deduplication? I don't see any activity on this place, may be i need to ask a particular person? Where the problem? May be a can i try to help (testing as example)? I could be wrong, but as i understand btrfs store crc32 checksum one per file, if this is true, may be make a sense to create small worker for dedup files? Like worker for autodefrag? With simple logic like: if sum1 == sum2 && file_size1 == file_size2; then if (bit_to_bit_identical(file1,2)); then merge(file1, file2); This can be first attempt to implement per file offline dedup What you think about it? could i be wrong? or this is a horrible crutch? (as i understand it not change format of fs) (bedup and other tools, its cool, but have several problem with these tools and i think, what kernel implementation can work better). -- Best regards, Timofey. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
