sync solution


Hi, I have a remote web server (running Ubuntu) and a local server (running Gentoo). Im looking for a way to keep the files on the remote box synced with the local box.

There's a large database to keep synced, some images and some larger files that Id like backed up at a pre defined time. Ive tried rsync but its painfully slow, especially with the images.

So Ideally a fast alternative to rsync, perhaps SFTP, but is it possible to have multi threads running on SFTP when its running from a script? Then how does it keep check of the new files and ignore ones already pulled down?

Many thanks!
Nige

I think you can do it in two steps: 1: rsync everything without images and 2: rsync only images. In the second step you can try "whole-copy", so rsync will not try to find matching blocks.

Hmm, but rsync is soo slow. Remote has a ridiculous connection and I have 60mb here. Remote is easily capable of maxing mine so ideally in the middle of the night Id like it doing just that. I do it currently with an FTP client. Id like it to be set and forget.

rsync is definitely planned for low bandwidth connections and to minimize the amount of the transferred data. Using -W (whole-file) will switch off rsync's optimizing algorithm and will transfer every file one by one (if required). You can give a try, probably it runs faster, it is quite similar to a simple ftp (just it will skip identical files)

So, its faster.

Quote:
6515442 100% 2.51MB/s 0:00:02 (xfer#10, to-check=820/845)
I can live with that, but would like something a touch faster.

Thanks again!!
