I was thinking of the snapshot speed, where most of the data hasn't changed. Do you keep a local cache of block checksums or something to avoid having to check the server? How about an option to not examine the data if the file size and mtime haven't changed? (like rsync does)
- cperciva 18y agoI was thinking of the snapshot speed, where most of the data hasn't changed. On modern CPUs, somewhere in the 20-50 MB/s range. Do you keep a local cache of block checksums or something to avoid having to check the server? Yes. How about an option to not examine the data if the file size and mtime haven't changed? (like rsync does) Tarsnap already does this for unmodified (file name, inode number, file size, mtime) tuples.
