Rsync not updating Webcam phnesex

When we reference rsync in this guide, we are mainly referring to the utility, and not the protocol.

Due to its ubiquity on Linux and Unix-like systems and its popularity as a tool for system scripts, it is included on most Linux distributions by default.

The bandwidth usage that is reported includes any speedup gained by having partial files on the destination side, so it may appear to be doing something that it's not. Note that if this option is not used, the optimization that excludes files that have not been modified cannot be effective; in other words, a missing -t or -a will cause the next transfer to behave as if it used -I, causing all files to be updated (though rsync’s delta-transfer algorithm will make the update fairly efficient if the files haven’t actually changed, you’re much better off using -t).

, which stands for "remote sync", is a remote and local file synchronization tool.

However, if you will use -t (without -u) with first rsync, the next rsync will of course transfer only changed file and the next attempt to rsync even without -t option will still copy only changed files.

I agree that not using -t, -u (or -c) is sub-optimal - but it works right now, where as using -u would actually introduce a bug (ignoring some remote files). :) Although it will affect -u more, because -t sets the time as seen from the source server, while -u relies on the target's notion of time.

To put this shortly: I recognize we can optimise this.

-u is not the right way, -c or -t [email protected] - I was confused a bit since I never used rsync without options, always with some mix or just -a, but you are right - the -u option would introduce a new layer of chaos/bugs in the already enough hard to understand magic introduced by this remote stuff in Aegir. So, at the moment we just play this safe, and we get rsync to check the contents of every file.

To quote the manual again: -t, --times This tells rsync to transfer modification times along with the files and update them on the remote system.

Note that if this option is not used, the optimization that excludes files that have not been modified cannot be effective; in other words, a missing -t or -a will cause the next transfer to behave as if it used -I, causing all files to be updated (though rsync’s delta-transfer algorithm will make the update fairly efficient if the files haven’t actually changed, you’re much better off using -t).
