1 This is the standard netbiff file system backend. It will understand any 2 file regardless of format since it relies on sizes and access time. It is 3 run without any arguments. The logic for biffing is such: 4 5 if file has been read more recently than written (atime > mtime) 6 send reset 7 else if file has been written more recently AND file size has increased 8 send update 9 else 10 do nothing 11 12 Netbiffd respects the following environment variables: 13 NETBIFFD_IGNORE_ATIME - If set to a non-zero integer, don't take file times 14 into account when sending updates.
