Asynchronous Backup

I am looking for a basic backup application that I can use to synchronize my files ONE WAY with my external HDD.

That is, my External HDD contains files that my Desktop HDD does not contain and I DON'T want them to be copied across to the desktop.

I have tried a couple of aplications but they all seem to want to synch both HDDs.

I just want the backp to check if the files on my Desktop already exist on the external HDD and if it new/newer version, copy across/overwrite to the External HDD, otherwise do nothing.

Can anyone please give me some pointers?

You can run rsync. In the most simple mode it is just a copy command like cp. But you will soon find that it can do a lot more ...

Read

Code:

---

man rsync

First browse it quickly, then read it a little slower to find what you want. This command from that manual shows a typical asynchronous backup command

Code:

---

rsync -av /src/foo/ /dest/foo

---

If you want to know what it 'plans to do' use the option

-n alias --dry-run

Code:

---

rsync -avn /src/foo/ /dest/foo

Thanks for such a fast response sudodus, I will give this a try and get back to you.
