end-of-stream - specify a callback to be called when a stream ends (which is surpsingly hard to get right)
duplexify - compose a Duplex stream from a Readable and a Writable stream
pump - pipe streams together and close all of them if one of them closes
pumpify - combine an array of streams into a single duplex stream using pump and duplexify
through2 - tools for making Transform streams
from2 - tools for making Readable streams

Linux Backup Solutions

I've been looking for the best Linux backup system, and also reading lots of HN comments.

Instead of putting pros and cons of every backup system I'll just list some deal-breakers which would disqualify them.

Also I would like that you, the HN community, would add more deal breakers for these or other backup systems if you know some more and at the same time, if you have data to disprove some of the deal-breakers listed here (benchmarks, info about something being true for older releases but is fixed on newer releases), please share it so that I can edit this list accordingly.

It has a lot of management overhead and that's a problem if you don't have time for a full time backup administrator.
