Ftp传输rsync-way

Question

我经常从ftp服务器(我无法控制,btw)下载日志文件,而且每次下载整个文件似乎都是rediciolus.

所以我正在寻找一个程序(linux-ish)或Perl模块,它在某种程度上结合了ftp和rsync,并且只"更新"文件.

日志文件不断增长.

有什么类似的吗？

Install curlftpfs (if on Windows, use cygwin)

# Create local mount path
mkdir -p /mnt/myftp

# Mount the destination ftp site using curlftpfs
curlftpfs -o allow_other ftp://myusername:mypassword@ftp.mydomain.com /mnt/myftp

# rsync inplace using append option
# use a long timeout value as the first long phase
# (the inplace comparison) takes a while
rsync -rzvvv --inplace --append --progress --stats --timeout=7200 /mnt/myftp/path/to/source/file.log /path/to/local/destination/file.log

# When you need to umount the ftp site
sudo umount myftp

# You can also mount from /etc/fstab by appending the following line
# curlftpfs#myusername:mypassword@ftp.mydomain.com /mnt/myftp fuse allow_other,rw,user,noauto 0 0
