I'm attempting to use Rsync (2.4.3) to update files between a Linux server,
and a Linux client with a mounted vfat partition (/c). I've heard about the
problem where windows mtime's arn't 100% accurate to the second, and
noticed that myself, but I'm not totally sure if vfat in linux mimics that
problem or not. I highly doubt it though.
The problem is this. If I run rsync with the following command:
rsync -rptS --timeout=240 --stats --delete --exclude-from=exclude.lst
[EMAIL PROTECTED]::sync/ /c/
It takes approx. 18minutes on a Celeron 333a 64mb ram client, same only
128mb ram server to complete the task. When using full verbose (-vvvv ) I
notice that rsync is calculating checksums for virtually every file if not
every file. (25,000 files, 1.5 gb's about) If I run the above line twice in
a row, one right after another (obviously no files have changed) it _still_
calculates checksums.
The weird part is this.
rsync -rptS --timeout=240 --stats --delete --exclude-from=exclude.lst
[EMAIL PROTECTED]::sync/windows /c/windows
If I run the above line, (just update the windows directory) the first time
it runs, all the checksums are calculated, (240megs or so) If I run it
again, immediately after, its completed in about 5seconds, no checksums are
calculated at all. (this is how it should be, correct?)
So why when I try to update the entire exported directory (or share, which
ever you want to call it?) at once (::sync/ /c/), it calculates the
checksums for every file, every time its run regardless, but if I just do
one directory at a time(::/sync/windows /c/windows/), it seems to work the
way it should? Thanks.
