Good way to incrementally back up files from ubuntu to win2008r2?
Hello
I have a client who needs to back up some flat files from a remote server running Ubuntu server 12.10 (which i know very little about), and they want to back them up to another server in another state via the internet, securely, but only sending changed files each night.
Currently the secure pathway is FTPS with filezilla server on the windows server (2008 r2), with a 2048bit ssl certificate. But, we can probably engineer almost anything else.
The first backup will be about 3gb - then maybe 25mb/day of changed files after that
What are some suggestions to get this done? It will be a push from Ubuntu into Windows, over the internet, and needs to be at least ssl secured.
I have almost no access to the Ubuntu server, i'm only relaying information to the admin in charge of that - i have full control over the server 2008 r2 machine and network.

Sandy - thanks for the reply. Will this work securely over the public internet? As far as i know, windows file sharing is possibly the most insecure what to expose a machine
That is right,,, it is not secure.. Create a IPSEC tunnel between the nodes and follow this exercise.. will be the easiest way to rid of it.

Hmm that could work - i don't know much about linux but is it easy for the admin in charge of the linux server to create an ipsec tunnel? we can endpoint them at a cisco ASA or pptp to the windows server too, which might be easier in linux?
I suggest do it over ASA.

How will rsync behave over the internet, when comparing files to know which to upload or not... you see what i mean, will it have to "download" the far side to compare to the local side to determine what should have to be updated? Or, does it keep track of what's been changed since the last upload, similar to the ntfs archive bit?
rsync makes a hash for each file so it only has to compare the local hash with the remote hash to decide if the file needs to be updated. For big files it makes a bunch of hashes that each represent a chunk of the file. This allows it to only send the portion of a big file that needs to be changed... this is really handy if your big files are the type that get appended instead of having the entire thing modified because all it has to send are the new bits.

alright, i've passed along the suggestion of rsync via vpn, and rsnapshot via vpn - two great suggestions
can anyone offer something that can happen by any secure means other than vpn, too?

2. Then mount that share at specific client.
3. Start #rsync by using source as your data and destination as shared directory mountpoint.
In my opinion this is the best way.
