Hi Guys!

I want to be able to make backups from a computer from my workplace to and external computer at home. This will have to be fully automated of course, maybe with a scheduler.

any suggestions?

I was thinking maybe FTP Sync with scheduler? Know of any good program if this is a good ideia of course...

I have a private VPN Server (in this case its SonicWall Router TZ210 and at home a SonicWall Router TZ100), for more security I can create a Site-to-Site vpn connection right?

I would love your input..thanks!

How much data are we talking about here? And I assume this would be blessed by company management or you own the company?

Yes, with two VPN endpoint router/firewalls, a site to site tunnel would be good the ideal. But keep in mind, once you set up the site to site tunnel, the tunnel will stay up all the time.

You could use SFTP for the transfers and save the complexity of working with the VPN tunnel.

LOL, Yes of course I have the Blessing of the company..and the data is going to a external PC in my Boss´s house...

Yes this is a problem withe the site-to-site...i dont want a big strain in the bandwith when having a connection like this when maybe it would be backed up once a week or maybe every 2 weeks...

JohnWill..SFTP good? what do I have to do? Can it be scheduled syncing or backup of files?
I have to setup the PC in my Boss´s house as a FTP Server...this PC has WinXP installed..what you recommend? SFTP is a server and client?

Thanks for the help guys I´ll be waitng for your opinions...

Well, FileZilla is a free FTP server and client that supports several encrypted transfer methods, it would probably do the job.

Another method is to use a syncing service, although I do not know of a free one. There are many for-pay ones; I am familiar with SugarSync. With something like this the initial upload to their servers and subsequent download to the home computer can take quite awhile, but after that each modified or added file is uploaded/downloaded almost immediately when there is internet access. You end up with 3 copies--business, online, home--pretty much all up to date depending on internet access.

Mozy is another on-line backup service, it's the one I use. It's only $4.95/mo for unlimited backup. With my 20/5 Verizon FiOS, even large changes get backed up pretty quickly.

[luisalvesnyde]

ok guys I´ll be checking them out...

not looking for online backup...I have a computer with 4TB HDD for backups...

[JohnWill]

Can't have too many backups.

[luisalvesnyde]

LOL..thats true..

I have the primary backup in the server room tape loader, then another backup syst4em..2 external HD´s in my office, and now this one setting up in my Boss´s house..LOL

[JohnWill]

Well, any significant amount of data going over the Internet could take some time, depending on the speed of your connection.

[luisalvesnyde]

yes thats true but this computer has all day to do so...

There's a way to help alleviate throughput issues over the internet. But I don't think it applies here or for most companies. I'm in the middle of evaluating and working with some WAN accelerators. The equipment I'm working with is the Cisco WAAS. The system does acceleration in a number of ways. One of the methods is by compressing data before it's sent over the WAN link. The other is via bit pattern matching. It'll also do local data caching so if the WAAS device sees data it has already in cache it won't go back to the source to get it. It'll just send it to the requesting host directly thereby cutting down on the need to initiate WAN traffic. There's also other things like TCP flow optimization.

The catch is the system is pretty pricey and requires a WAAS device (either an appliance or router expansion card) at each end of the communication along with a central manager.

Doing some testing, I've been able to simulate WAN traffic with a latency of 300 ms to do a worst case scenario moving a 600 MB file. Before injecting the WAAS, it took about 1hr and 30 mins. After inserting the WAAS, it went down to about 37 seconds.
