Cheap offsite backup

AJNS asked
Last Modified: 2008-02-27
I'm looking into providing off site backup for a couple of small companies. At present I'm not charging for it since I'm hoping it will lead into bigger things with them. But since I'm not charging for it I need to do it cheaply.

All systems involved are running Windows and I have a VPN set up with each site. I don't want to do a data dump each night since there is too much data. I would like a program that synchronizes the files in real time as they change through the day or just copies the changes at the end of the day.

I took a look at cwRsync without SSH since I already have vpn. Will that take care of this for me? Are there any other programs that will do this?

I got a wide variety of responses so let me clarify a little.

I don't want to use 3rd party solution, the data must go directly from the customer to my server. I have a similar setup running at other companies, much bigger companies, using Symantec/Veritas continuous protection server complex isn't an issue, just price.

These smaller companies have around 30gb of data but most of it doesn't change much and when it does its more of an edit then a complete change so to keep it cheap as far as time/bandwidth rsync's method seems perfect, it will just backup the changes. They are already doing backup to tape but

So what I guess I'm looking for was some assurance that Rsync is reliable. Not being a linux guy I've just come across it and wanted some reassurance before I put it into production.

But if its the "Gold Standard" as SysExpert said then great. But are there any alternatives to it?
